The online knowledge base comes from the cooperation of Hanser, Matplus GmbH and Dr Ulrich Brill. Designers and process engineers can compare the creep-rupture data that Dr Brill brought together in the reference work Zeitstandverhalten von metallischen Werkstoffen (Hanser, 2019).
That reference covers creep-rupture data for 199 iron-base, 77 nickel-base and 23 cobalt-base alloys, drawn from international sources and the author’s own investigations. The online edition is maintained on an ongoing basis, so the live coverage can differ from the 2019 book.
The data describe strength and creep resistance as a function of temperature and time. They do not replace short-term hot tensile properties. The threshold of about 0.4 of the melting temperature is the homologous temperature used in the Hanser reference: the ratio of the service temperature to the melting temperature, both in kelvin.
