metal powder alloys

In a broad sense, metal powder alloys can be broken down into three categories: alloys based on nickel, stainless steel, and titanium. Each of these alloys brings a distinct set of benefits to the sector of production in which they are used. However, the process of choosing a particular alloy necessitates that you take into consideration a number of different criteria. These include the feedstock that is used in the production of the metal powder alloys, the temperature at which the powder is pressed, the characterization of the powder, and the procedure that is utilized in the production of the finished product.

Stainless steel

Applications that operate at high temperatures frequently make use of stainless steel powder alloys. These alloys have a high resistance to corrosion and have excellent mechanical qualities. They are capable of being constructed in a wide variety of states. They are able to be manufactured in forms that are either entirely crystalline or amorphous, as well as nanocrystalline composites. The milling duration, the environment during the sintering process, and the type of sintering procedure all play a role in determining the density of the powder particles.

Spheroidization of stainless steel powder alloys is possible through the use of an induction plasma spheroidization technique. After that, they are sent through a ball milling machine to be treated. In this method, the powders are first brought to the suitable temperature, and then they are ground for a predetermined amount of time using a particular medium.

Cold isostatic pressing vs hot isostatic pressing

In the past, welding ceramic powders were often produced by a process known as cold isostatic pressing. In contrast, the application of this method during the production of metals has only recently become more prevalent. The procedure is broken down in great length in this page, along with a discussion of the benefits and drawbacks associated with it.

In cold isostatic pressing, the pressure applied is typically in the range of 100 to 600 megapascals (MPa). This is not enough to achieve considerable densification with the current amount. However, it has the potential to make the final product easier to handle and to boost the overall yield of the component.

On the other hand, hot isostatic pressing is performed in an environment consisting of gaseous molecules. The powder compact is subjected to this pressure, which is applied in all directions. The presence of voids in the powder can be eradicated by applying a high pressure. In addition to this, the qualities of a wide variety of ceramic materials are enhanced. It is also possible to utilize it to blend powdered metal with other types of materials.

Characterization of powder feedstock

There is still a lack of precise ways to describe powder feedstock for metal powder alloys, notwithstanding the advancements that have been made in the field of additive manufacturing (AM). The metal powder alloys can come in a wide variety of forms, and each of these forms has its own particular set of characteristics that distinguish it apart from the others. It is essential to have a good understanding of the transformations that take place in powders during the production process in order to be able to determine which powders have the best quality and efficiency.

In order to overcome this obstacle, innovative methodologies for the characterisation of powder feedstock have been devised. These methods can be utilized to determine the distinctions that exist between powders, which paves the way for the creation of quality control measures and the preliminary screening of new materials.
