高温合金广泛用于航空、航天、舰艇、发电等发动机制作高温零件.它承受高温、应力和被介质腐蚀的作用.高温合金在使用过程中如果出现大量的片状拓扑密排相(TCP相),往往造成力学性能的严重降低,威胁着航空发动机和燃气轮机等动力设备的安全使用.因此,近20年来,从事高温合金研究 High temperature alloys are widely used in the production of high temperature parts of engines such as aviation, spaceflight, naval vessel, power generation, etc. They are subject to high temperature, stress and corrosion by medium.If a large amount of flaky topological dense phase (TCP phase) , Often resulting in a serious reduction in mechanical properties, threatening the safe use of aero-engines and gas turbines and other power equipment.Therefore, nearly 20 years, engaged in high-temperature alloy research
