Microstructure and Property of a New Metastable β Titanium Alloy
The evolution regularities of microstructure and property of a new metastable β titanium alloy with different solution treatment and aging treatment were studied using optical microscope (OM),scanning electron microscopy (SEM) and tensile test.The results show that,the volume fraction of primary α phase decreases and globularization of α phase occurs with the increasing aging temperature from 540℃ to 580℃ and solution treated temperature from 800℃ to 820℃.When the solution treated temperature is 820℃,the acicular secondary α phase precipitates along β grain boundary.The strength of the investigated alloy increases and the ductility decreases with the solution treated temperature increasing.While the strength of the investigated alloy increases and the ductility decreases with the aging temperature decreasing.
