Testing technology

Material testing

Induction heating can also be found in science and material testing technology. For example, metals are heated in scientific experiments in order to then subject them to mechanical loads. In this way, shear and tensile strength, expansion coefficients, etc. can be recorded.

Inductive heating is preferable to heating in an oven if a high temperature gradient is required. The rapid and replicable heating of the test specimens enables constant process parameters as well as time and cost savings. Furthermore, long test times have negative effects on the metal-physical properties (precipitation, coarsening, recrystallization or creeping) of the test objects. The homogeneity of induction heating compared to furnace heating cannot be guaranteed 100% though and is more difficult to achieve.
