| Abstract: | The effects of heat treatment on mechanical properties and wear resistance of low alloy white cast iron were studied by optical microscope,scanning electron microscope and material properties tester.The results show that heat treatment Call improve mechanical properties and wear resistance of the cast iron,and in combination with deformation,the effects are more remarkable.After 25%deformation and normalizing at 980℃for 2 hours,the impact toughness and wear resistance of the cast iron increase by 71.95%and 8.6%,respectively. |
