Changes in the Structure and Properties of Single-Crystal Refractory Alloys Under Long-Term Operation

  • REFRACTORY ALLOYS

Metal Science and Heat Treatment Aims and scope

The structure and properties of carbon-containing single-crystal alloy ZhS32 and carbonless single-crystal alloys ZhS36, VZhM4 and VZhM5U are studied after 500 – 3000-h aging at 850 – 1100°C. The resistance to elastoplastic strain, creep and fatigue and the characteristics of long-term strength of the alloys are determined. It is shown that the expected values of long-term strength and creep resistance of the single-crystal alloys should be corrected with allowance for the changes in their initial structure after long-term operation.
