| Abstract: | Conclusions Mo-Cu and Mo-Cu-Ni composites produced from powders by sintering and subsequent infiltration belong to the class of particle-strengthened workable materials. Plastic working of Mo-Cu and Mo-Cu-Ni composites by rolling or extrusion has a marked beneficial effect on their strength and ductility. The mechanism of strengthening is the same as that operative in reinforced materials. The materials exhibit no marked anisotropy of mechanical properties. It should be possible to formulate Mo-Cu and Mo-Cu-Ni composites having similar values of CLTE and at the same time differing substantially in their mechanical properties.Translated from Poroshkovaya Metallurgiya, No. 12(204), pp. 76–81, December, 1979. |
