| Abstract: | Different amount of niobium alloy was added into the high thermal conductivity cast iron with CE of 4.4%~4.5% used for brake disc,and the effect of the niobium on the microstructure and mechanical properties of the casting were investigated.The result showed that,when CE was of 4.4%,Nb was of 0.09%,the graphite of the high thermal conductivity cast iron brake disc became finer,its mechanical properties were increased in some degree,its wear loss was reduced,its hot cracking resistance was improved. |
