摘要

The stability of austenitic FeCrNi alloys to martensitic transformation is essential for the operation of cryogenic components in motion. High strength, sufficient ductility and the absence of ferromagnetism are desired properties. Results of ball-on-disc sliding tests are presented. Examples are given for testing at room temperature and conclusions are made for low temperatures equivalent to the boiling points of nitrogen, hydrogen and helium. Changes in the alloy microstructure are shown by light microscopy, scanning electron microscopy, magnetic induction, and X-ray diffraction methods. The influence of liquid hydrogen on structure transformation is taken into special consideration, since it decreases the stacking fault energy of the materials, and favours martensitic transformation.
