由多层金属和陶瓷构成一体的梯度功能材料，因为各层成分的逐渐变化而实现其热膨胀系数的连续逐渐变化的热应力缓和型耐高温材料，这就是最早开发成功的梯度功能材料，用于宇宙飞船的机身能耐受高达１８００℃的高温。热应力缓和用梯度功能材料另一个典型材料，便是高性能切削
The multi-layered metal and ceramic gradient functional material, because of the gradual changes in composition of the layers to achieve a continuous gradual change in thermal expansion coefficient of thermal stress relaxation of high temperature materials, which is the earliest developed gradient functional materials for The spacecraft’s body can withstand up to 1800 ℃ high temperature. Another example of a typical material for graded functional materials for thermal stress relaxation is high performance cutting
