GH 132合金的过烧,将导致各项性能降低和一系列组织变化。若经多次热加工,这些变化将变得更加复杂。本文对多次热加工后的过热合金的持久性能不合格原因及矫正措施作了论述。
Overheating of the GH 132 alloy results in various performance reductions and a series of organizational changes. With multiple thermal processes, these changes will become more complex. In this paper, the causes of overdriven alloy after repeated hot-working and the corrective measures are discussed.
