苏联的粉末冶金工业在巨变之前是相当小的,看来是由于能源和原材料的成本高以及在这两方面考虑使用粉末冶金在经济上的可能性的直接结果。一个苏联粉末冶金学家指出:用铁粉制造每一千吨产品可节约130万卢布和2250吨钢,而且能解放出234个工人和48台金属切削机床作别的工作用。与美国的发展水平相比,苏联粉末冶金的应用稍微落后一点。这主要是由于苏联车辆产量低,但是随着新的汽车和商业车辆的全部投产,所需的粉末冶金零件数量将引人注目地上升。估计到1980年全部粉末冶金部件将达到十万吨(1970年为4万吨)。
The Soviet Union’s powder metallurgy industry was quite small before the catastrophe, and appeared to be a direct result of the high cost of energy and raw materials and the economic viability of using powder metallurgy in both areas. A Soviet powder metallurgy scientist pointed out that it would save 1.3 million rubles and 2,250 tons of steel per kilogram of product made from iron powder and would free 234 workers and 48 metal-cutting machines for other jobs. Compared with the level of development in the United States, the Soviet Union’s powder metallurgy application a little behind. This is mainly due to the low output of Soviet vehicles, but with the full production of new vehicles and commercial vehicles, the number of powder metallurgy parts required will rise dramatically. It is estimated that by 1980 all the powder metallurgy parts will reach 100,000 tons (40,000 tons in 1970).
