CONSTRUCTION ELEMENT SUBJECT TO THERMAL STRESSES, PART OF SUCH ELEMENT

摘要

A heat-conducting construction element subjected to thermal stresses (or corresponding construction element section) on which a temperature drop occurs during the operation of the machine where it is mounted. At least one layer (21, 42a, b, 45, 58) of metal hydride, hydrogen-tight and thermally conductive layer is interposed in the construction element 10, 37, 38, 33, 50 perpendicular to the profile simulating the drop in temperature 23. /P P Application in particular to heat engines.
