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.

Whether or not the nominalist position about this is acceptable, the nominalist paraphrasing tactic to avoid commitment to the existence of universals while explaining the truth of sentences seemingly about universals sometimes fails.

无论关于这个的唯名论立场是否可以接受，唯名论的改写策略（避开对共相存在的承诺，而解释关于共相的语句的真）有时会错，其他关于共相的语句不能按改写'蓝是颜色'的方式进行解释。
