Experimental Study on Heat Yreatment Processing of a New Low Cost Titanium Alloy Used in Aviation Field

摘要：

　　The effect of common solution treatment,two-step solution treatment and aging,solution treatment and aging (STA) on the microstructure and mechanical properties of a new low cost titanium alloy used in aviation field were investigated by optical microscope (OM),scanning electron microscopy (SEM) and tensile test.The results show that a typical equiaxed structure can be obtained by common solution treatment leading to a good combination of strength and plasticity.Besides,solution heat treating in the β region and subsequently ageing at a low temperature results in a significant increase in mechanical strength and a little decrease in plasticity.When the solution temperature is at α+β two-phase region (895℃),the low cost titanium alloy acquires the best combination of strength and ductility.
