The following test methods were developed: the small‐cup tension test, the mantle compression test, and the ball compression test. They are applicable up to very high temperatures. The experiments with model materials and NiAl‐ and TiAl‐compounds were combined with plastomechanical calculations by the method of upper bound of deformation power and by the method of finite elements.
