1·The undercooled DZ125 superalloy was investigated by the method of glass and molten salt purification combined with cycled superheating, the mechanism of purification by compound salt was discussed.
采用自制净化剂和循环过热相结合的办法，研究了不同净化剂对DZ125高温合金的净化效果，探讨了复合熔盐的净化机理。
2·As shown by calculation, for binary cycle, superheating system is not preferred.
计算结果表明，对双工质循环采用过热系统是不可取的。
3·It revealed that alternating stress in long time cause the bolt fatigue failure, meanwhile the failure process was also effected by superheating steam.
认为主要原因是螺栓在长期服役中受交变应力引起疲劳失效所致。过热蒸汽介质对疲劳失效有影响。
