新型梯度材料梯度材料（ＦＧＭ）就是二种不同材料合成的，其组成、显微结构、性能都呈阶梯状连续变化的新材料。开始它是为航天飞机发动机研制的，因其燃烧室一面是二千多度的燃烧气体，一面是温度极低的液氢，在这样恶劣环境下，任何材料都不行。为此，研制了具有热应力... New Gradient Material Gradient Material (FGM) is a new material synthesized by two different materials, whose composition, microstructure and properties are continuously changing in steps. Initially it was developed for the space shuttle engine because its combustion chamber is more than two thousand degrees on the one hand the combustion gases, the other is the very low temperature liquid hydrogen, in such a harsh environment, no material can not. To this end, developed with thermal stress ...
