Some studies on sintered cold deformed plain carbon alloy steels

Steel of Fe–0.8%C with and without addition of 1.0%Mo were considered for the present investigation. Experimental analysis was studied for attained density against induced strain parameter. Various stress parameters were determined and studied for its behaviour against strain. Instantaneous plastic Poisson’s ratios of were computed and was compared with conventional. All these characteristics were extensively studied under the influence of composition as well as aspect ratios; however, friction condition and initial density of the preforms were kept constant.

► The influence of geometry and effect of 1.0%Mo in Fe–0.8%C during cold upsetting is investigated.
► Relationship between density, Poisson’s ratio, stress, strain and strain factor is discussed.
► The inclusion of 1.0%Mo improves the load bearing capacity irrespective of aspect ratios.
► A power law relationship between the fractional theoretical density and eεz-εθeεz-εθhas been established.
