Foamed precious metals 泡沫贵金属
The processes of making porous materials composed of metallic fibres and foamed metals were briefly introduced.
简单介绍了金属纤维多孔材料和发泡金属的制造方法；
When the biaxial nominal stresses are equal to each other, the mathematical relationship between loading strength and porosity can be also gained for the foamed metals under biaxial equal loads.
当双向承受的名义应力相等时，还可得到泡沫金属在双向等荷承载条件下的载荷强度与孔率的数学关系。
