一些高强度球铁件的生产,可采用若干30毫米厚的针状球铁基尔试块来进行下列几方面的研究:(1)硅和镍对铸态球铁机械性能的影响。(2)不同回火处理对一般球铁的影响。(3)回火对高硅和低镍球铁拉伸性能的影响。
Some high-strength ductile iron pieces can be produced by using several 30 mm-thick acicular iron Kiln test blocks for the following studies: (1) Effects of silicon and nickel on the mechanical properties of cast ductile iron. (2) the impact of different tempering on the general ductile iron. (3) tempering on high silicon and low nickel ductile iron tensile properties.
