Characterization of Cold- and Warm-Formability of Metallic Materials (MCL-SP3)

The aim is to develop a thermo-mechanical testing device for the experimental determination of various thermo-physical materials properties. These data should subsequently be used in computer simulations of casting, forming and forging. The device will be applicable in a temperature range between ambient temperature and 1600°C. At these temperatures, most iron and nickel base alloys of practical interest can be heated up into the fully liquid region. The mechanical properties that will be covered by the current project are (i) flow-curves from tensile and compression testing at ambient and elevated temperatures, (ii) tensile testing in the partially liquid region to determine the influence of the primary solidified microstructure on the formability of the material, (iii) determination of the Brittle-Temperature-Range (BTR), which is located between the Nil-Ductility-Temperature (NDT) and the Nil-Strength-Temperature (NST) and (iv) creep- and relaxation measurements at very high temperatures.
