PM-TiAl基合金热处理及其性能
Heat Treatment and Performance of PM-TiAl Base Alloy
摘要
Abstract
In order to optimize the usability, microstructure and mechanical property of TiAl based alloy after hot isostatic pressing and hot treatment was studied. After heat-treatment of 1 355℃ , organization of TiAl based alloy transformed to full lamellar microstructure. After heat-treatment of 1 335℃ , organization of TiAl based alloy transformed to double pattern microstructure. Tensile strength of full lamellar TiAl under room temperature is 446 Mpa, and will increase with temperature; yield strength of full lamellar TiAl under room temperature is 386 Mpa, and will increase with temperature.关键词
