【Abstract】 The effect of different matrix structure on thermal fatigue resistance of spheroidal graphite iron (S.G. iron) were studied. The results show that the thermal fatigue resistance of ferrite matrix of S.G. iron is best and complex phase matrix is detrimental to increase in thermal fatigue resistance.更多还原
