    ABSTRACT Surface hardening of GCr15 bearing steel ring was carried out using CW CO(2) laser. The laser power used was in the range of 300 to 500 Watts. A rectangular beam shape was used to cover the area to be hardened. A three fold increase in the hardness of the transformed zone was achieved. The depth of hardness attained was around 1mm.

    Austenite grain growth behaviour of Nb-bearing microalloyed steels The grain growth rate was significantly slower in microalloyed steels with higher contents of Nb. Grain growth control in microalloyed steels has been shown to be dependent on the amount of microalloying additions (Alogan et al., 2007; Hodgson and Gibbs, 1992).
