Abstract A new beta titanium alloy Ti–8Mo–8Zr–4.5Sn–2Mn was designed, and melted by non–consumable electric arc furnace in argon atmosphere. The metallographic microstructure, the crystal texture, hardness and elastic modulus were characterized by microscope, X–ray diffractometer and nano–hardness Tester. The results show that the alloy contains dendritic structure and equiaxed grain structure, exists alloying element segregation and has the elastic modulus with 41.4GPa. Meanwhile, comparing to TMA(Ti–11.5Mo–6Zr–4.5Sn), the effects of the electron concentration e/a, the combined number Bo and the d electron orbital energy level Md on the elastic modulus were investigated. The conclusions was obtained that the low of Bo and Md and the increase of e/a are beneficial to reduce the elastic modulus of alloy.
