在低温范围内，多晶bcc金属的工程屈服强度可发生10倍以上的变化，严重后果为灾难性脆性断裂。已知对屈服行为有重要影响的工程变量是应力状态、温度、载荷或应变率、成分和微观结构。对于铁、铬、钼和钨，屈服行为可以用两个无量纲参数之间的单值关系来表示。
In the low-temperature range, the engineering yield strength of polycrystalline bcc metals can change by a factor of 10 or more with serious consequences appearing in the form of catastrophic brittle fracture. Engineering variables known to have an important effect on the yield behavior are state of stress, temperature, loading or strain rate, composition, and microstructure. For iron, chromium, molybdenum, and tungsten, it is shown that yield behavior can be represented by a single-valued relation between two dimensionless parameters.
