尽管很早就有人提出等径角挤压技术,但是直到20世纪90年代初才得到学者的重视.主要介绍了该技术的国内外最新研究成果,以及目前还存在的问题,并对今后的研究提出了几点意见.
Although the equal channel angular pressing is inducted a long time ago, the scholars have an interest in it only since beginning of the 90s in the last century and they have also gained a series of achievements. This paper mainly introduces the effective results that the scientists have obtained and the deficiencies to be concerned.
