| Abstract: | Ti60 alloy powder and silicon carbide nanowires(SiCnw)were mixed by ball milling,and SiCnw/Ti60 composite was prepared by spark plasma activation sintering process.Using scanning electron microscope,X-ray diffractometer and universal testing machine,the microstructure,phase structure and mechanical properties of SiCnw/Ti60 composite were studied.The results show that the matrix grain size is significantly reduced after adding SiCnw to Ti60 alloy.Compared with Ti60 alloy,the grain size of SiCnw/Ti60 composite with 0.1%(mass fraction)SiCnw decreases by 42%,and tensile strength increases by 2.7%to 1037 MPa.The uniform distribution of SiCnw at the grain boundary has pinning effect.During the stretching process,SiCnw bears the load transfer between the substrates,which improves the tensile strength of SiCnw/Ti60 composite. |
