| Abstract: | Effects of RE modification and heat treatment on carbide morphology and mechanical properties of cast semi steel were studied. Experimental results show that the dissolution and breaking up of eutectic carbide network and precipitation of granular carbides are notably accelerated during high temperature holding of the RE modified cast semi steel, as a result , the mechanical properties of cast semi steel are greatly improved. |
