  Dynamic Hardness Trend of Tribological Steels Used for Advanced Power Transmission Assembly

  By Prantik Mukhopadhyay, Rajnish Goyal, Manish Roy

  Abstract: Gravity drop technique was used for measuring dynamic hardness trend of M50, 52100 and 4340 tribological steels. Work hardened state increased dynamic hardness, while shear bands and dynamic recovery of dislocations induced dynamic softening. Descending order of work hardening for the investigated steels is M50-52100-4340. The threshold strain to begin the softening gradually increases in the order M50-52100-4340 steels. Descending order of work softening beyond threshold strain for the investigated …
