The influence of prior plastic deformation on the creep process is studied for copper and an aluminium alloy. Variations of basic creep parameters due to differences in temperature of realized tests are also taken into account. Moreover, the paper reports the prestraining effects depending on the type of prior deformation. It is shown for both materials that, depending on the deformation history, the basic creep parameters may attain values which are more beneficial from the engineering point of view than those for the non-prestrained material determined. It is also shown that, in some cases, prior plastic deformation may lead to detrimental effects expressed, for example, by reduction of the lifetime.

W pracy przedstawiono badania dotyczące wpływu wstępnej deformacji plastycznej na proces pełzania miedzi i stopu aluminium. W doświadczeniach uwzględniono wplyw zmian temperatury na podstawowe parametry pełzania. Omawiane są również efekty zależne od rodzaju wstępnej deformacji. Dla obu badanych materiałów pokazano, że zależnie od historii deformacji podstawowe parametry pełzania mogą ulegać poprawie w stosunku do parametrów otrzymanych dla takich samych materiałów testowanych w stanie dostawy. Przedstawiono również warunki, przy których wspomniane parametry ulegają istotnemu pogorszeniu (np. obniżeniu żywotności).
