The Effect of Ferro-Molybdenum Addition on the Microstructure and Mechanical Properties of Sintered Steel

In this study, various ratios of ferro-molybdenum were added into low alloy distaloy steel powder and then the compacts were fabricated by powder metallurgy process. The effect of ferromolybdenum addition on the properties of these sintered materials such as density, microhardness and impact toughness were investigated. The results obtained from experimental works showed that ferro-molybdenum addition to the starting powder resulted in an increment in density and microhardness values. On the other hand, ferro-molybdenum addition has influence on impact toughness values of the sintered low alloy steel.
