Behaviour of Crystal Boundaries in Aluminium and its Alloys during Melting


WE have recently been engaged on an examination of the mechanical properties at temperatures in the region of the solidus of super-purity aluminium and high-purity alloys in the three binary alloy systems, aluminium–copper, aluminium–iron and aluminium–manganese. In this work, tensile tests have been carried out at elevated temperatures in a modified Hounsfield tensometer on small cylindrical test pieces of the alloys, the technique and apparatus being similar to those used by Singer and Cottrell1.
