摘要
为了实现转子材料的国产化,对钢的高温力学性能进行分析,通过蠕变试验和应力弛豫试验,研究了温度、初始应力对蠕变行为的影响,并分析了应力指数、表观激活能等特征值。
To realize localization of rotor materials, mechanical propertie peratures are studied. From the creep tests and stress relaxation tests, the ture and initial stress on creep is investigated. Analysis is also done on the stress index and activation energies. s of steel at high teminfluence of temperacharcteristics such as
