The resistance to thermal fatigue on ductile iron is studied in detail.
对不同基体球铁的抗热疲劳性作了实验研究。
By proper solution treatment the grain size of alloys was moderate, thus a good combination of strength, plasticity and the resistance to thermal fatigue was obtained.
采用适当固溶温度处理，该二合金晶粒度适中，可获得强度、塑性和抗热疲劳性能较好的配合。
Compared with the forging die steel, casting forging die steel although toughness is low, but high strength, red hardness is good, with low notch sensitivity and high resistance to thermal fatigue.
与锻造模具钢相比，铸造热锻模具钢虽然韧性低，但强度高、红硬性好，具有较低的缺口敏感性和较高的抗热疲劳性。
