| Abstract: | W/Cu functionally graded material (FGM) was fabricated by infiltration-welding method. The first process is to choose appropriate amount of pore-making additives and suitablecombination of W powder with different particle sizes to fabricate a W skeleton with graded porosity,the second step is to infiltrate molten Cu into the graded pores and the third step is to weld this W/Cu transition layer to pure W plate by hot pressing. The microstructure of the as fabricated W/Cu FGM was observed and thermal shock resistance was tested. |
