一、前言 对于低碳钢中魏氏组织对机械性能的影响,大体上有两种不同的看法,一种看法认为魏氏组织会降低钢的机械性能,特别是降低钢的冲击韧性;另一种看法认为魏氏组织不会降低钢的机械性能,甚至在某些情况下还会提高其性能。出 First, the preamble For the low carbon steel Wei’s organization on the mechanical properties, in general, there are two different views, one view that Wei’s organization will reduce the mechanical properties of steel, especially to reduce the impact toughness of steel; the other The belief is that Wessel’s organization does not reduce the mechanical properties of the steel and, in some cases, improves its performance.
