Applicability of a deformation dilatometer for short time creep experiments of magnesium alloys
Abstract
The creep resistance of light metals is of utmost relevance for application at elevated temperatures. This includes automotive components in power trains, engines, battery casings and transmission housings. The alloy design of temperature resistant light alloys for these applications depends heavily on the timely determination of the creep behavior. However, specialized facilities and testing equipment are required to perform creep experiments, which are not available in all labs. In contrast, deformation dilatometers are state-of-the-art at most research facilities with a metal forming department. These instruments can apply a constant force at high temperatures and are therefore, in principle, able to conduct creep experiments. To validate the applicability of such a deformation dilatometer for the development of magnesium alloys, short time creep experiments were conducted and compared with results from a standardized creep stand. Good agreement between the dilatometer and conventional constant force creep experiments was found. In this work, both methods are described in detail and possible limitations are discussed.
