Incorporating silicon carbide whisker or particulate into aluminum matrix creates a formable, machinable and relatively inexpensive composite. SiC whisker or particulate reinforced aluminum matrix composites are generally fabricated by the molten aluminum infiltration of whisker (or particulate) preforms, or by a powder metallurgy technique involving hot pressing at a temperature near the solidus of the matrix alloy. The room-temperature and elevated-temperature properties of these composites have been studied by many investigators. It has been shown that these composites have a high specific strength and stiffness as well as good elevated temperature strength and resistance to creep deformation. However, the investigation about the cryogenic properties of these composites has not been reported to date. It is important to understand the cryogenic properties, considering the practical application of these composites. The purpose of the present paper is to investigate the cryogenic properties and fracture behavior of SiC whisker and particulate reinforced 2xxx aluminum alloy composites.
