Experimental Investigations on Heat Treatment of Cold Work Tool Steels : Part 1 , Air-hardening Grade ( D 2 )

The present experimental investigations deal with the improvement of mechanical properties of cold work tool steels through different heat treatment processes. An attempt was made to get optimal combination of hardness and toughness through changes of microstructure by heat treatment. The toughness of D2 tool steel increases with tempering temperature. The… CONTINUE READING
