The vacuum electron beam welding method is used for TA12
and the surface of the sample shows well. Through optical microscopy
tensile and fatigue experiments
and other methods
the microstructure and mechanical properties of the joints are studied. The results show that the TA12 alloy joint with good performance can be obtained by electron beam welding
which meets the requirements of a welded structural component
and the microstructure is mainly martensite phase.
