Study on the Microstructure and the Mechanical Properties of TA2

Abstract:

The microstructure and the mechanical properties of welding joint with the material of TA2 have been studied in this paper with the specimens made with the method of argon-arc welding. The microhardness of the welding joint has been compared with the hardness in the same position of the weld joint after annealing. Conclusions have been obtained as follows: The organizations of the welding joint include base material, recrystallization zone, overheated area, fusion zone and the weld zone; the hardness tendency of the weld joint is depicted as M-shape with the softest point located at the center, and the hardest is located at the overheated zone; the annealing treatment can enhance the weld joint hardness mainly at the center, and the hardness of other zones change little.
