对于热加工变形的金属(即在重结晶作用伴随变形作用的温度条件下)所进行的广泛研究表明,重结晶颗粒的大小、亚颗粒大小以及位错密度随稳态流动应力而系统地变化,与温度及总应变(在小的临界应变之后)无关。Twiss(1977)曾评介这些研究结果,并且还推导出了重结晶颗粒大小,亚颗粒大小与流动 Extensive research on thermally processed deformed metals (ie, temperature conditions where recrystallization accompanies deformation) shows that the size, sub-particle size, and dislocation density of recrystallized grains systematically vary with steady-state flow stress, Independent of temperature and total strain (after a small critical strain). Twiss (1977) reviewed the results of these studies and also deduced the recrystallized grain size, sub-grain size and flow
