In situ TiB2/ZL101 composite prepared by mixed salts reaction is a kind of new structure-functional material with many advantages such as light weight, high specific strength and specific stiffness, small thermal expansion coefficient, high wear resistance, corrosion resistance and size stability etc.. Currently, metal matrix particle reinforced composite has great porosity, segregation and interface reaction tendency which seriously affect the performance of weld joints. In order to solve these problems an...
