/Al composite parts with complex shape can be produced successfully by combination of powder injection molding (PIM) for SiC preform preparation and aluminum pressureless infiltration. The effect of sintering process on open porosity and strength of SiC preform was researched, and the thermo-physical characteristics of final composites were also evaluated. The results show that the best sintering......
