摘要：
The 30CrMnSiA plate with 2 mm thickness which is applied extensively in aerospace industry was welded by vacuum electron beam, and the microstructures and mechanical properties of joint were investigated. The results indicate that a well-formed joint can fabricated by vacuum electron beam with various welding parameters. Due to intensive heat and rapid cooling rate, the typical lath martensite is formed in fusion zone and the grains in the narrow heat affected zone are grown greatly. The microhardness and tensile strength of joint exceed to 600 Hv and 1400 MPa, respectively, which are extensively higher than that of basic metal. The fracture is occurred in the heat affected zone during tensile experiment.
