✦ Synopsis

Specimens of two commercial graphites were hot-isostatically pressed at 2700Β°C to more than 95 per cent of theoretical density. These were compared in creep to unpressed specimens from the same artifact. The creep curves were similar in shape; strengths were equal, creep ductilities were equal, and stress and temperature dependences of the creep rate were identical. The pores and cracks present in the original material did not seal during the densification process. The creep deformation modes were the same.

Hot isostatic pressing has been applied for the consolidation of four commercially available nitride powders, i.e. titanium, tantalum, zirconium and hafnium nitrides and the reactivity in oxygen of cubic specimens is compared. Two types of behaviour have been recorded: 0 the oxidation of the titani

## Abstract Ti/NiCr20TiAl and NiCoCrALY/IN617 composite materials have been produced by vacuum plasma spraying, Arc‐PVD and hot isostatic pressing. Regarding their mechanical and technological properties they are dependent on the heat treatment during the production process. Therefore optimized str
