| Abstract: | High volume fraction SiCp/Al composite is a perfect electronic packaging material due to its excellent thermal-physical properties and lower density.In the present study,the SiCp/Al composites were prepared by powder injection molding-pressureless infiltration technology,and the effects of SiC particles characteristics on thermal cycling behavior and mechanial properties were researched.The results showed that SiC particle size and volume fraction have an obvious effect on thermal dimensional stability of S... |
