Research on Mechanical Properties of Machined Electron Beam Weld of TaW12 Alloy AITranslate
Abstract AITranslate
Vacuum electron beam butt welding was carried out on 3mm thick TaW12 alloy sheets,and then the welded sheet was successively thinned to 2mm and 1.5mm by cold rolling,exhibiting good cold workability of the electron beam weld of TaW12 alloy.Tensile test results show that the tensile strength of the alloy can only reach 699.65～721MPa by simple electron beam welding with 9.38%～13.15%elongation.However,the tensile strength of the machined weld of 1.5 mm thick sheets can be up to 934 MPa,about 93.8%～94.7%tensile strength of 1.5mm thick cold-rolled substrate,and its elongation reaches 8.0%～9.0%.And all the weld tensile samples fracture along the weld center.The cold-rolled electron beam weld has higher strength and plasticity,attributed to weld microstructure refinement and pore decrease caused by cold rolling.
