The Influence of Starting Material on Rheological Properties Non-Ferrous Alloy

The result of researches are commonly accessed in professional literature. Many authors describe the influence different grain size on flow stress *sp and limited plasticity. Many of them are publishing opposite dates obtained in various conditions. The results of systematic plastometric researches non-ferrous metals for different condition of starting material are presented in the work. In the results of researches were fixed, that rheological characteristics of investigated materials depends on structure and grain size. The cooling rate after homogenizing treatment of billet before hot plastic working have fundamentally influence on formability. Influence of cyclic deformation in RKUP conditions was investigated. Optimal value of those cycles no structure and mechanical properties investigated material were determinate.
