Thermodynamic test process for materials used in aeronautics and automobile construction

摘要

System for thermomechanically characterizing materials through an induction heating device for reaching a temperature of 3,300 DEG C in a maximum of 20 seconds. The high speed heating device (11) comprises inductor means (27a, 27b, 27c) arranged at least partly about the sample (21) and producing induced currents; susceptor means (23) arranged between the sample and said inductor means for transforming the induced currents into heat rays; heat protection means (25) arranged between said inductor means and said susceptor means for protecting said inductor means from heat rays emitted by the susceptor means; and insulating means fully surrounding the inductor means. The system of the invention is applicable in fields using new materials such as aeronautics, the car industry and the like.
