Abstract

Magnesium alloy deformation should be carried out at high temperature and it is essential to investigate the deformation behavior of these alloys at high temperature. In this paper, practical tests are conducted on AZ80 alloy which includes tension and compression tests at high temperature and different strain rates. As this alloy is sensitive to temperature and strain rate, tension tests are difficult to carry out. The traditional compression test should be conducted in zero-friction condition but such a condition is impossible to prepare. Therefore, bulge correction factor and numerical correction factor are used to eliminate the friction effect which exists between the surfaces. Tensile tests are also carried out on the standard specimens at high temperature and different strain rates. The effect of necking phenomenon is corrected using Bridgman correction factor and is simulated using finite element software. Also T-shape compression test is used to valuate friction parameter at high temperatures.
