采用熔渗－焊接法经过梯度W骨架制备，渗Cu及热压焊接三个步骤制备出W／Cu功能梯度材料。并对W／Cu梯度过渡层的显微结构进行了观察．对W／Cu功能梯度材料的热震性进行了测试
The W / Cu functionally graded material was prepared by melt infiltration-welding method through three steps: preparation of W skeleton, infiltration of Cu and hot pressing. The microstructure of W / Cu gradient transition layer was observed. The thermal shock resistance of W / Cu functional graded materials was tested
