Влияние размера зерна и структурного состояния границ зерен на параметры сверхпластичности нанои микрокристаллических сплавов

Влияние размера зерна и структурного состояния границ зерен на параметры сверхпластичности нанои микрокристаллических сплавов

Abstract

Предложена модель, позволяющая вычислять размер зерна dopt, оптимальный для деформации в условиях сверхпластичности нанои микрокристаллических (НМК) материалов, полученных методами интенсивного пластического деформирования. Модель основана на представлениях теории неравновесных границ зерен в металлах. Получена зависимость величины dopt от скорости и температуры деформации, а также термодинамических параметров материала. Проведено сопоставление с экспериментальными данными по сверхпластичности НМК алюминиевых и магниевых сплавов.

A model has been proposed for calculating optimal grain size dopt for superplastic deformation of nanoand microcrystalline (NMC) materials produced by severe plastic deformation (SPD). The model is based on the concepts of the theory of nonequilibrium grain boundaries in metals. The dependences of dopt on the rate and temperature of the strain and the thermodynamic parameters of the material have been derived. A comparison has been made with the experimental data on the superplasticity of aluminum and magnesium NMC-alloys.
