然后对渗碳淬火钢齿轮的弯曲疲劳试验数据用JFKC法进行计算，得到了它的疲劳极限应力分布，并对比其相应的成组试验法测定的疲劳极限应力分布进行了分析和讨论。

Mechanisms of heat affected zone liquation and liquation cracking in GH150 alloy were investigated by using varestraint test and hot ductility test in conjunction with the differential thermal analysis and optical, scanning electron microsopy. On heating,γ/C liquation take places in the HAZ above 1250℃. When the temperature reaches 1353- 1375℃, a large amount of liquid particles due to initial melting can be observed within the grains near the fusion boundary. On cooling,γ/C eutectic and γ/ Laves phase eutectic take place at 1273 and 1200℃ respectively.
