作为超高温材料使用的梯度功能材料作为以难熔金属及其化合物为主要成分的梯度功能材料，要求具有综合的功能和梯度变化的构造。实现以下目的：（１）缓和热应力。在不互溶的金属－金属系混合物中，Ｗ／Ｃｕ系梯度功能材料受到最广泛的关注，类似的材料还有Ｍｏ／Ｃｕ系。... Gradient functional materials for use as ultra-high temperature materials, as gradient functional materials based on refractory metals and their compounds, require constructions with integrated functional and gradient changes. Achieve the following purposes: (1) to ease the thermal stress. W / Cu graded functional materials have received the most widespread attention among immiscible metal-metal compounds, and similar materials include Mo / Cu compounds. ...
