英文摘要	Using pulsed laser welding method, the connection between Zr44Ti11Ni10Cu10Be25 (at%) bulk metallic glass and 304L stainless steel plate was realized. The microstructures and chemical compositions of different regions of weld joint were characterized by field emission scanning electron microscope, energy dispersive spectrometer and X-ray diffraction. Three different crystallization zones were formed due to different coo-ling rates. The weld joint consists of partial crystallization zone (heat affected zone, weld zone and 304L stainless steel/weld zone interface) and amorphous zone (Zr-based bulk metallic glass base metal). Petal-like and small-particle crystallization occurs in heat affected zone. The intensity of diffraction peaks in X-ray diffraction pattern is very small. Some cross-snowflake crystallization appear in weld zone. The diffraction peaks correspond to Zr2Cu and Zr2Fe phases. A large number of sharp crystal peaks appear in XRD pattern at 304L stainless steel/weld zone interface. The results show that the crystallization fractions of heat affected zone, weld zone and 304L stainless steel/weld zone interface are 1.4%, 10.0% and 27.4%, respectively. The Vickers hardness of the crystalline microstructure formed in the weld zone is the highest. The diffusion layer formed between BMG and weld zone indicates that Zr migrates to weld zone through diffusion layer during welding. © 2020, Materials Review Magazine. All right reserved.
