自1940年发现合金软化现象后,人们在这方面已进行了许多研究。然而关于合金软化机理,还有分歧。例如,对铁-镍、铁-钛合金现多用内禀理论来解释,研究也较多;对铁-钒合金现仍沿用外禀理论来解释,研究较少。内禀理论认为,溶质原子与体心立方结构中位错的 Since the alloy softening phenomenon was discovered in 1940, many studies have been conducted in this area. However, the mechanism of alloy softening, there are differences. For example, the iron-nickel, iron-titanium alloys are mostly used to explain the intrinsic theory, more research; the iron-vanadium alloy is still based on the use of exogenous theory to explain, less research. Intrinsic theory suggests that the solute atoms are dislocated from the cubic structure of the body
