Behavior of Metal Matrix Composites at Cryogenic Temperatures

Abstract

A cryogenic mechanical testing facility was constructed capable of testing materials from 4.2 degrees Kelvin to room temperature. Three tensile test were performed on P55 Gr/6061 Al metal matrix composites. At 4.2 degress Kelvin, the elastic modulus was 21.7 million psi and the ultimate tensile strength was 85.1 jsu, At 77 degress Kelvin, the elastic modulus was 20.5 million psi, and the ultimate tensile strength was 78.4 ksi. At 293 degrees Kelvin, the elastic modulus was 27.4 million psi, and the ultimate tensile strength was 93 ksi. Keywords: Metal matrix composites; Tensile behavior. (SDW)
