XRD data indicate that this ECAP processing causes the XRD peaks to broaden.

XRD数据显示ECAP加工增加了织构并使衍射峰变宽.

Cu-Cr alloys with different mass percentages of chromium were prepared by equal channel angular pressing(ECAP).

制备不同质量百分含量铬的铜铬合金试样，对合金试样进行等径角挤压（ECAP）处理。

Cu - Cr alloys with different mass percentages of chromium were prepared by equal channel angular pressing ( ECAP ).

制备不同质量百分含量铬的铜铬合金试样,对合金试样进行等径角挤压 ( ECAP ) 处理.

Approaches to present status of the ultra-fine grain materials processed by ECAP were performed and some further research issues were proposed.

论述了由等径角挤压方法制备超细晶材料的发展现状并提出了一些需要进一步深入研究的方面。

This adversely affects the ability of ECAP to refine grains as it depends on accumulated dislocations and other defects to form ultrafine grains.

变形温度高则回复快，晶体缺陷消失速度快，不利于晶粒的细化，甚至还会出现晶粒长大现象。

ECAP has the similar deformation style with cold rolling since both have the similar appearance with strap texture which improving the alloy's anisotropy.

ECAP变形与冷轧类似，都形成极其相似的带状织构，提高了合金的各向异性常数。

The results show that the microhardness of CuCrZr alloy increase rapidly and electric conductivity decreases appreciably with the increase of ECAP passes numbers.

结果表明，随着挤压道次的增加，合金的硬度迅速上升，导电率略有下降。
