To reduce the cost of powder metallurgy (PM) components, approaches such as increasing densities to enhance mechanical properties or using
lower cost alloying elements to improve the cost performance ratio have been used.
Nickel, copper, and molybdenum have been the most common alloys used in PM. Nickel and copper are very efficient alloying elements,
offering a good balance between properties and ease of utilization. However, PM is competing for nickel powders with the ever-growing
battery market leading to price increases. Additionally, copper has been on the list of elements to replace for sustainability issues. Moreover,
molybdenum is a very costly alloying element.
Ferrochromium is a lower cost alloy and is typically used in the prealloyed state, reducing possible segregation, and improving part-to-part
stability. This paper will compare the performance of a low alloy chromium grade compared to common grades.
