Abstract

The effect of adding Ti on the microstructure and properties of electron beam welded molybdenum joints had been investigated in this study. It is found that the depth-to-width ratio of welded joint with the addition of Ti, which can be explained by the mechanisms of molten pool flow and energy absorption. Meanwhile, the addition of Ti promotes the formation of Ti₆O₁₁ as a second phase during the welding process, which acts as a strengthening agent, reducing the grain size in the molten pool region and subsequently enhancing the mechanical properties of the joints, with the tensile strength increased by 400%.

在电子束焊接过程中引入钛，提高钼的可焊性

研究了添加Ti对电子束焊接钼接头组织和性能的影响。结果表明，加入Ti后，焊接接头的深宽比可以用熔池流动和能量吸收机理来解释。同时，Ti的加入促进了焊接过程中第二相Ti6O11的形成，Ti6O11起到强化剂的作用，降低了熔池区域的晶粒尺寸，提高了接头的力学性能，抗拉强度提高了400%。
