某些铸造合金钢构件如何达到所要求的延性与韧性水平,长期以来,一直是军械生产中感到棘手的问题。其中,问题之一就是产品性能不均匀。当这些性能低于所要求的水平时,构件在使用中就可能发生危险破坏事故和降低使用寿命(此时要求费用很高的早期更换工序)。目前,美国陆军材料与力学研究中心的研究员已经证明,通过均匀化热处 How some of the cast alloy steel parts reach the ductility and toughness levels required has long been a problem that arose in the production of ordnance. One of the problems is the product performance is not uniform. When these properties are lower than the required level, the components may be in danger of being destroyed and the service life will be reduced, in which case the expensive replacement process is required. Currently, researchers at the US Army’s Center for Materials and Mechanics have demonstrated that by homogenizing heat
