摘　　要：研发了高温真空可充气环境蠕变疲劳试验装置,实现了高温真空可充气环境中金属材料的蠕变、持久、疲劳等安全性能的测试。试验装置由3部分组成：复杂应力加载机构及其测控系统、1500℃加热-冷却机构及其测控系统、真空可充气气氛结构及其充气压力测控系统。试验装置可实现高温真空或充气环境中多种波形自由组合动态加载,频率0.01~1Hz可调,加热温度高达1500℃。该试验装置为高温复杂应力真空可充气环境下材料性能数据库建立、失效机理研究、相关理论模型的试验验证等提供了有力的装备支撑。A new creep fatigue testing apparatus in vacuum or inflatable environment at high temperature is developed,which can be used for creep,fatigue,creep-fatigue interaction test and so on. The testing apparatus consists of a loading system,a heating system and vacuum or inflatable environment system. The specimen can be loaded in various waves-such as sinusoid wave,triangular wave and trapezoidal wave,and the waves can be arbitrarily combined with frequency range of 0. 01 to 1Hz by the testing apparatus. The highest test temperature is up to1500℃. The testing apparatus provides an instrument for safety property test,establishment of material property database and failure analysis of metallic materials in vacuum or inflatable environment at high temperature.
