WebLiquid metal embrittlement (also known as LME and liquid metal induced embrittlement) is a phenomenon of practical importance, where certain ductile metals experience drastic loss in tensile ductility or undergo brittle fracture when exposed to specific liquid metals. Generally, a tensile stress, either externally applied or internally present, is needed to … WebWhite steel isn't necessary more brittle than blue steel all things equal. However the chemistry of white steel allows you to push higher Rockwell hardness numbers than blue steel, upwards of 65 rc A higher hardness can lead to an edge more likely to chip. More important than Steel or heat treatment I would argue is the edge geometry.
