摘　　要：纳米技术和纳米材料具有广阔的应用前景,尤其是致密、无污染的块体纳米材料,其制备技术中,等径角挤压变形是制备块体纳米金属结构材料最有效的方法,并具有工业化应用前景。There are many application prospects for both nano- technology and nano- materials, especially for dense and non - contaminafive bulk nano - materials. In the preparation techniques of bulk nano - materials, equal channel angular pressing is the most effective one and possesses a better prospect of industrial applications.
