| 摘 要： | 通过感应熔炼、铸造、锻造和冷拔变形制备了Cu-16Fe-2Cr(质量分数,％)原位复合材料,最终线材(其轧制后的冷拔变形量达到η=ln(A_0/A)=5.42,A_0和A分别为冷拔起始和冷拔后线材的横截面面积)的抗拉强度为980 MPa。将Cu基体选择腐蚀后提取出纤维,采用SEM和TEM观察分析纤维相组织形态。在较低的应变量时,一些Fe—Cr纤维保持着与铸态树枝晶相同的bcc单晶结构,选区电子衍射表明纤维已经形成了〈110〉织构。在较高的应变量时,单根Fe-Cr纤维分为一些由晶界隔开的平行亚单元(宽度约为100 nm),通过亚单元共同的110]衍射获得了晶粒之间的相对取向关系,相邻晶粒的偏差角在11°—82°之间。根据Hall-Petch关系讨论了原位复合材料的强度问题。
