摘要：
The addition of small amounts (1%) of nickel were sufficient to activate liquid-phase sintering and improve phase interface adhesion and the mechanical properties of molybdenum-copper pseudoalloys with a complex bimodal pore structure. The pseudoalloys retained high porosity (up to 75%) after sintering. This was achieved by lowering the microporosity in the biporous materials, thus decreasing the total amount of shrinkage which occurred during the sintering process.
