Abstract: Purpose:The purpose of this work is to investigate the forming behaviour studies on Fe-Mo-Cr alloy produced by powder metallurgy method. Design/Methodology /Approach:In this study , Ferrous alloy Mo powders and Cr powders were accurately weighed and blended in ball mill to yield the different compositions namely(Fe,2%Mo and 2%Cr).The blending was carried out in ball mill with the 18mm diameter stainless steel balls.The balls and powders weight ratio is 5:1 and the speed of the drum was 150rpm.The milling was carried out for a period of 3 hours .Blended powders were pressed in dies under high pressure to form them into the required shape.The work part after compaction is called a green compact .In powder compaction process the powders were compacted under high pressure by various methods to pack the powders and reduce the porosity.The Fe,Mo and Cr powders were sintered in an electric muffle furnace in the temperature 12000C for a period of 1 hour and cooled to room temperature in the furnace itself.The sintered preforms were characterized by SEM analyses and it revealed that the uniform distribution of reinforcements (Mo&Cr).The true axial stress (Ϭz),true hoop stress (Ϭϴ)and true hydrostatic stress (Ϭm) increased with the addition of MO and Cr particles in pure steel matrix during cold upsetting .The formability stress index (β)increased with the addition of 2 weight percentage of Mo Cr reinforcements in pure steel matrix during cold upsetting. Findings: The powder metallurgy process is replacing traditional metal forming operations because of its low relative energy consumption ,high material utilization,and low capital cost.Also the uniformity in reinforcement distribution can be achieved by the powder metallurgy process to produce porous structures and this improves structural properties and also reproducibility . Originality/Value:This paper explains the effect of Fe-Mo-Cr alloy produced by powder metallurgy method.
Keywords: Powder metallurgy ,Ferrous alloy,Molybdenum ,chromium,Forming behavior.
