BJT powders optimized for desktop metal solutions. You can improve the performance of your BJTs by using PTF-aluminium 6061 powder in desktop metal solutions.
When compared to standard PMC alloys, powder thixoformed (PTF) 6061 aluminum alloy powder have significant advantages. They are capable of rapidly solidifying complicated aluminum alloy components. They are also less expensive than powder metallurgy. They can also be used to create functionally graded structures.
The alloy PTF-6061 contains eutectic and secondary primary a phases. It has a tighter microstructure than the PMC-6061 alloy. The Thermo-Calc diagram can be used to identify these phases in the powder microstructure.
A comparison of a traditional permanent mold cast alloy and PTF-6061 alloy revealed that the PTF process was more effective in reducing porosities. However, the deposit's ultimate tensile strength was equally crucial to the tensile yield strength. This was owing mostly to the presence of secondary solidified structures.
The PTF approach was also successful in improving tensile strength and solid solution strengthening. However, the effect of solution temperature on tensile strength is not as clear. This discrepancy emphasizes the importance of a more precise understanding of the powders.
To reinforce the powder, the PTF process employs a matrix. As a result, the composite has a higher density and better densification. PTF techniques can also be used to create particle reinforced aluminum matrix composites with high strength. They have the potential to be a significant replacement for traditional PMC.
After three hours of solutionizing at 535oC, the PTF-6061 alloy had the best overall mechanical characteristics. The alloy has a porosity of 0.16%. The PTF alloy has lower solute atom concentrations than the PMC-6061 alloy. However, from 535oC to 585oC, the solute atom concentrations are still larger than in the PMC alloy.
Moreover, the PTF-6061 alloy exhibited superior tensile strengths at a solution temperature of 560oC. The eutectic phase was still present in the gas atomized powder, indicating that the microstructure of the powder still retained some of its characteristics after solution heat treatment. This was also shown in the form of an improved coating produced from the solution heat-treated powder. This coating showed a higher concentration of dislocations in the interfacial zone, facilitating particle-particle bonding.
Aluminum alloys are employed in a variety of industries such as automotive, chemical, food processing, marine structures, and rail transport systems. This article compares the properties of aluminum alloy 6061 (AA6061) with those of 5052 (Al-Mg-Si) and PMC-6061 (PMC6061). AA6061 is a great all-purpose alloy. This alloy has a good combination of qualities, including strength, hardness, workability, and wear and corrosion resistance.
The microstructure response of AA6061 was predicted using a multi-stage fatigue model. The fatigue nucleation, nucleation propagation, and total fatigue life were all incorporated in this model. This model was evaluated on a heat-treated AA6061 specimen that had been artificially aged. The expected and experimental findings were nearly identical.
The reverse loading experiment and compression-by-tension (CBT) were two of the experimental procedures studied. CBT can produce a composite with enhanced tensile strength and elongation, according to the results. The composite's ultimate tensile strength increased from 230 to 128 MPa and its elongation increased from 275 to 212 MPa. This composite is a strong contender for usage as a high-strength forming alloy. However, it is difficult to become tired.
AA6061's microhardness was determined to be equivalent to that of its base metal. Furthermore, a kinematic-to-isotropic hardening ratio near unity was discovered. These findings show that AA6061 retains its low-cycle fatigue performance even after heat treatments.
The nano-dimensional powders or Ito Nano Powders utilized in the research exhibited the following properties: a size range of 150 nm to 1.0 I. Particle morphology includes agglomerated particles, primary a-Al particles, and iron-aluminide oxides; 1/4 m; (FeAl3). These particles have been demonstrated to increase feedstock viscosity and improve injection capacity. This composite has excellent mechanical properties, including high fatigue resistance, tensile strength, and elongation.
Following that, the FEA data were used to create a multi-stage fatigue model that included fatigue nucleation, nucleation propagation, total fatigue life, and microstructure response. The multi-stage fatigue model is used to forecast AA6061's reaction to stress-controlled low-cycle fatigue. The multi-stage model was found to be capable of predicting AA6061's reaction to fatigue nucleation and propagation.
An interesting observation was the development of localized slip bands in the 6061 alloy. This phenomenon is known as the Bauschinger effect. It indicates that the AA6061 alloy has the capacity to develop an isotropy. In addition, the study investigated the development of striation fields in the aluminum alloy. This phenomenon has a metallurgical significance because it demonstrates that aluminum alloys can be deformed under conditions that are suitable for low-cycle fatigue.
The new 6061 aluminum powder was developed after a multi-year partnership and is optimized for use with Desktop Metal Systems, the industry's leading turnkey AM solutions. It has a high density and a high ultimate tensile strength, as well as elongation of more over 10%. This enables users to obtain a fully dense 6061 Aluminum item while using the least amount of energy. It is intended to be an alternative to traditional aluminum sintering techniques, which required coating powder particles or incorporating sintering aids into powders.
Uniformity Labs and Desktop Metal have collaborated to provide an optimized Aluminium 6061 powder for use with the binder jet 3D printing technique from Desktop Metal. This ground-breaking powder is designed to provide a low-cost alternative to typical aluminum sintering processes while maintaining high density and ultimate tensile strength.

This low-cost raw material yields parts with good ultimate tensile strength, elongation, and minimal energy levels.
The proprietary technique used by Desktop Metal ensures consistent material qualities throughout the part production cycle. This results in a fully dense 6061 Aluminum product with negligible porosity, resulting in a significant increase in throughput. The procedure delivers repeatable, quick layering with this high flow powder, resulting in a 50% improvement in throughput.
The Aluminium 6061 powder is designed as a low cost alternative to traditional aluminium powders, which require a high energy mechanical stirring to overcome the wettability between the aluminium matrix and the reinforcement. This is accomplished through high pressure infiltration of molten Al into the preform. In addition to reducing the cost of the powder, this high density and high ultimate tensile strengths make this a superior raw material option.
AA6061 is the market's second most common aluminum alloy. It is typically extruded and has a variety of mechanical qualities. Magnesium, silicon, and aluminum are all present in the alloy. Originally known as Alloy 61S, it is now known as 6061. This alloy is well-known for its excellent strength and resistance to corrosion. Additionally, the alloy is machinable and has high mechanical qualities.
AA6061 has mechanical qualities close to Vickers microindentation hardness. Mechanical characteristics range between 110 and 150 MPa. The ASM International determined and listed these parameters. Following that, the mechanical properties were employed to create a set of tensile test specimens. To characterize the powders, many metallographic methods were applied.
XPS and a DAVINCI design diffractometer were used to examine the powders. Powder phase analysis was also carried out with the use of Bruker D8 DISCOVER and VANTEC-500 area detectors. The powder's morphology was also investigated using a TESCAN VP scanning electron microscope. The findings were then used to create process maps. These maps contribute to the quality of the as-built pieces.
The powder bed heating approach yielded tensile specimens with a microhardness of 119 HV. This is a minor percentage, but it is significant for the final section. The morphology of recycled powders also accounts for a minor percentage, however it may have no effect on the final part.
Both powders had essentially identical chemical makeup. The Fe content of the LB methods was lower, while the C concentration was higher. The process maps revealed that the SLM process parameters were tailored to each material. The high resolution oxygen test also made use of these factors.
The initial powder's morphology was classified as typical aluminum powder metal particle size distribution. The profile of this particle size distribution was positively skewed. This profile has more tiny particles and has a greater surface quality. The recycled powders also displayed a positively skewed profile with a higher fine particle percentage. This profile has a higher apparent density and greater flowability.
The mechanical properties of the AA6061 powders were evaluated in accordance with the ASTM F3049-14 standard. These properties were compared to the mechanical properties of a typical aluminum alloy powder. A summary of the microhardness values is presented in Table 2.
