Mechanical Behavior of Be-Al Alloys

Abstract

This study was conducted to identify the mechanical behavior of a wrought 62Be-38Al alloy and a cast 65Be-32Al-3Ni alloy. Tensile strength and elongation were measured at room and elevated temperatures. Fracture toughness was determined at room temperature. Fracture resistance 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 resulting microstructures and crack paths of the aforementioned were also examined.
