    摘要:

    劇烈塑性變形制備超細(xì)晶金屬材料是當(dāng)前的研究熱點(diǎn)?；跈C(jī)制和微觀組織變化綜述了劇烈塑性變形制備塊狀超細(xì)晶材料的一些方法，特別是給出了兩種新型成形技術(shù)-等截面橢圓變通道扭擠和等截面橢圓轉(zhuǎn)變通道扭拉，此外還闡述了劇烈塑性變形存在的問題及未來的研究方向

    Abstract:

    Ultrafine-grained (UFG) metal materials processed by severe plastic deformation (SPD) have attracted the great interest. This overview introduces some attractive SPD techniques. Special attention is paid to two new deformation techniques named Elliptical Cross-section Spiral Channel Extrusion with Equal-area (ECSEE) and Elliptical Cross-section Spiral Channel Drawing with Equal-area (ECSDE). The mechanism and microstructure transformation characteristics of materials in SPD, current problems and ongoing research are also discussed in detail
