SiCp / Al composites , thermal vacuum sintering deformation This paper studies preparation process , the main influencing factors of the SiCp / Al composites cold pressed density , hot-pressing deformation amount of research and analysis of these factors under the influence of various state SiCp / Al composite microstructure and mechanical properties. Element Powder prepared SiCp / Al composites cold press density , as well as secondary hot deformation amount . The results show that : (1) In this paper, cold pressed sintering and hot deformation prepared 12vol.% SiCp/2024Al process of composite materials can be prepared in accordance with performance indicators composite , the process parameters were : cold-pressed density 85% ; sintering process 580 ℃ × 120min; 45% of the amount of hot pressing deformation ; sINTERED billet density of 82.7% , after hot deformation can reach more than 97% . (2 ) Cold higher density and a more uniform microstructure of the composite material . Density to 85% in the cold-pressed , heat distortion SiCp / Al composite microstructure distribution . After thermal deformation, the distribution of the matrix SiC particles improved significantly, and a significant increase in density . (3) the amount of deformation of 45% , the enhancement of the particles along the direction of the deformation extending streamlined . The higher the amount of deformation of SiCp / Al composites higher density SiCp / Al composites density when the deformation reaches 54% , to 2.8092 g/cm3 , the density reached 99.81% , with 45% deformation little difference. The amount of deformation reached 54% , the transverse yield strength of the composite material was 375 MPa, a tensile strength of 530MPa ; the longitudinal performance relative to the diameter direction to be worse , the amount of deformation reached 54% , the yield strength of 360 MPa . Material elongation and reduction of area rate increased by 166.7% and 233.3% than the vacuum sintering state .
