Mechanical Properties of Be-Al Alloys

Abstract

This study was conducted to define the mechanical properties of a wrought 62Be-38Al alloy and a cast 65Be-32Al-3Ni alloy. The tensile strength and elongation were measured at room temperature, 66 degrees C (150 degrees F), 121 degrees C (250 degrees F), 177 degrees C (350 degrees F), and 232 degrees C (450 degrees F). The fracture toughness was determined at room temperature. The fatigue behavior was characterized in terms of stress-life (S-N) and crack growth rate - stress intensity range (da/dN-delta K) relations at room temperature. The microstructure was examined, and the crack path was identified for each mechanical testing.
