据苏联《有色金属》月刊报道,苏联乌斯特卡缅诺哥斯克道路建筑学院研制成的钴基合金含有镍、铌、锰、硅。为了在保持弹性数值和导电率前提下,提高抗衰减性,疲劳强度和可塑性,在钴基合金中再加入混合稀土。钴基合金的组分比例如下(%):镍27—29;铌4.8—5.2;锰0.1—0.3;硅0.1—0.3;混合稀土0.02—0.2;余量为钴。 According to the monthly report of the Soviet “Nonferrous Metals”, cobalt-based alloys developed by the Institute of Road Construction of the Ust-Kamenogorsk Institute of the Soviet Union contain nickel, niobium, manganese and silicon. In order to improve the anti-decay resistance, fatigue strength and plasticity under the premise of maintaining the elasticity value and conductivity, mixed rare earths are further added to the cobalt-based alloy. The composition ratio of the cobalt-based alloy is as follows (%): nickel 27-29; niobium 4.8-5.2; manganese 0.1-0.3; silicon 0.1-0.3; mixed rare earth 0.02-0.2; balance cobalt.
