Abstract

Semi-solid tin bronze blanks was prepared by cold rolling-isothermal treatment SIMA method (CRITSIMA method), and then tin bronze bushing parts were extruded. The effect of isothermal treatment time on the microstructure and mechanical properties of thixotropic tin bronze bushing parts is investigated. The results show that with the increase of isothermal treatment time, the average grain size gradually increased, the coarsening rate of solid grain is 296 μm³/s, the shape factor first increased and then decreased, the Brinell hardness first increased and then decreased, the tensile strength gradually decreased, and the elongation first increased and then decreased. The microstructure and comprehensive properties of the tin bronze bushing are the best when kept at 910℃ for 15 min. The shape factor is 0.74, the average grain size is 63.56 μm, the tensile strength is 368 MPa, the elongation is 4.5%, and the Brinell hardness is 126 HBW.

Key words: metal materials copper alloy isothermal treatment thixotropic extrusion microstructure mechanical properties
