The microstructure and mechanical properties of TA15 joints by laser forming connection

The microstructure and mechanical properties of laser forming connected joints of TA15 fabricated by hot isostatic pressing (HIP) process were investigated. The results showed that high-quality joints are produced by laser forming connection (LFC). The connection zone (CZ) consists of the columnar g...
