摘要：

Two types of TiAl6V4-powder, different in shape and grain size, were used to produce test specimens to measure their mechanical behaviour. The manufacturing of the samples was performed by hot isostatic pressing (HIP) or by metal injection moulding (MIM). The microstructure and the taking up of impurities, e.g., oxygen, carbon, nitrogen, during the individual process steps, were determined by SEM and chemical analysis. Tensile- and creep-tests were carried out at temperatures of up to 600-degrees-C, the results being compared to a forged TiAl6V4 reference material. In order to optimize the mechanical properties, different heat-treatments were carried out between 600-degrees-C and 1050-degrees-C. The results obtained are dependent on the manufacturing route and heat treatment. In this paper the variation of the properties obtained by varying the manufacturing route are presented in some detail.
