摘要

粉末高温合金由于其独特的生产工艺，往往在成形件中会产生夹杂物、原始颗粒边界（PPB）等缺陷。根据镍基粉末冶金（Powder metallurgy，PM）高温合金制造的主要工艺流程追溯碳化物、氧化物的遗传演变过程

分析其对成形件组织结构、裂纹扩展速率及疲劳寿命的影响，从而获得抑制消除缺陷的方案。

Abstract

Due to its unique production process

powder metallurgy superalloy often produces defects such as inclusions

previous particle boundary (PPB) in the formed parts. In this paper

the heredity and evolution of carbide and oxide in alloy were traced back according to the manufacturing process of Ni–based powder metallurgy (PM) superalloy

and their effects on microstructure

crack growth rate and fatigue life of formed parts were analyzed. The schemes of restraining and eliminating defects were proposed.
