dc.description.abstractThe properties of Austenitic Manganese Steel (AMnS), used for rock drilling, was optimized as a highly cost efficient and preferment material for the mining industry. To achieve this, inter-critical annealing and homogenization heat treatments operations were employed. Subsequently, relationships were established between various process parameters, mechanical properties, microstructure and alloying elements. Emphasis was given to the control of grain size and phases, most particularly secondary carbides. Hardness, impact and microscopy investigations were carried out on the heat treated samples. The results show an improvement in hardness and impact characteristic of the AMnS. The microstructures of the heat treated samples show substantial grain refinement and a uniform dispersion of secondary carbides along grain boundaries.en_US
