Ring rupture strength and hardness of sintered hot-forged 1.5Mo alloyed carbon steels
The effect of fractional density and height-to-diameter ratio (aspect ratio) on radial crushing strength for sintered hot-upsetted Fe–0.8%C as well as Fe–0.8%C–0.5%Mo powder metallurgy rings were investigated. Rings of predetermined geometry were machined from the hot deformed preforms of different...

| description | The effect of fractional density and height-to-diameter ratio (aspect ratio) on radial crushing strength for sintered hot-upsetted Fe–0.8%C as well as Fe–0.8%C–0.5%Mo powder metallurgy rings were investigated. Rings of predetermined geometry were machined from the hot deformed preforms of different initial densities. It was found that increasing density of the rings had increased the radial crushing strength irrespective of compositions. Further, it was observed that the hardness values were continuously increasing with increasing fractional density. Increasing the aspect ratio of preforms substantially increased the hardness values for any theoretical density attained. It was also observed from fractographs that majority of the rings crushed in a brittle manner. |
