Research on Mechanical Properties and Microstructure of Laser Welding Joint of Automotive TC15 Titanium Alloy AITranslate
Abstract AITranslate
Mechanical properties and microstructure of laser welding joint of TC15 titanium alloy were studied by tensile test, hardness test and metallographic analysis. The results show that depth-to-width ratio of welding line ranges between 4 and 6. Columnar crystals are distributed in weld area symmetrically aside the weld center line,and they are mainly large grains of βphase. The heat affected zone consists of fine grain zone,coarse grain zone and recrystallization zone. And the grains nearby the fusion line are significantly coarsened. The weld zone has relatively stable hardness distribution and close hardness to the coarse grain zone. The weld sample with low welding current has the minimum tensile strength, and its fracture is in the weld zone. With welding current increasing,the welding joint has improved tensile strength.
