摘要
梯度功能材料(FGM)是指材料的组分沿厚度方向连续变化,从而使材料性能也呈梯度变化的一种新型材料。列举了多种FGM的制备方法,分析了FGM的热震、压缩等性能及实验手段,展望了FGM新的发展方向。
Functionally gradient material （FGM） is one of the new materials, because its composition shows a continuous change along thickness orientation. Consequently, its performance shows a continuous change too. Fabrication methods and performance evaluation of mechanical properties, thermal shock, compression and heat treatment for FGM are discussed in detail. At last, the new developing directions of FGM are analyzed.
