alloy steel powder

Using alloy steel powder for a variety of applications necessitates an understanding of several crucial factors. For instance, knowing the mechanical properties of the fabricated parts can be crucial for determining whether the alloy is suitable for the intended application.

Application criteria for alloy steel powders

The heat treatment of alloy powder increases the tensile strength and abrasion resistance of sintered components. According to the innovation, alloy steel powders may meet four criteria: hardness, compressibility, strength, and toughness. Moreover, the innovation is inexpensive and requires no specific environment during the sintering process.

The present invention may also be accomplished by combining powdered alloy with powdered ferrophosphorus. Phosphorus is a powerful solution-based steel strengthener. In the Fe-P phase diagram, it generates a narrow g loop. In addition to stabilizing ferrite, it guarantees that the bulk of metal powder is absorbed by the molten flux. The quantity of phosphorus supplied must be sufficient to enhance the steel's hardness.

The total weight concentration of Cu and Ni must be between 0.6% and 1.5%. These two components are crucial to the fortification of the sintered body. Throughout the manufacturing cycle, the quantity of every component must be measured.

Models for simulating secondary atomization

There are several models for modelling the secondary atomization of alloy stainless steel powders. The technique of atomization is also known as one-time crushing. This method fragments large droplets of molten material into smaller droplets before solidifying the powder. It is a crucial technology for creating spherical powders with minimum oxidation. It is appropriate for additive manufacturing (AM) powder production. Additionally, it decreases excess powder inventory and gas use.

Utilizing ANSYS fluent 19.0, the secondary atomization process of the high-temperature alloy melt was simulated. It was discovered that the interaction between the solid, liquid, and gas throughout the process had a substantial effect on the powder's microstructure. The control of a number of influential elements was investigated. Additionally, the powder's properties were evaluated. In terms of tensile characteristics, microstructure, porosity, porosity ratio, and porosity polarization resistance, the powders were examined.
