TESTING OF THE THERMOMARKER : IMPORTANCE OF HYSTERESISM. RAYMOND and E. WEYNANT
IMAGO bâtiment Delta, Athélia I, F-13600 La Ciotat, France
After a short presentation of the industrial machines used by the process of treatment of shape memory alloys, the paper will explain the special feature of the Thermomarker which falls in with two tests of working : one during the martensite-austenite transformation, one during the austenite-martensite transformation. So that the good work of the Thermomarker is bound directly to hysteresis. The authors will display not only results but also the analysis they have made to get a goodcorrelation between this working hysteresis and the hysteresis of the martensitic transformation in shape memory alloy.
