【Abstract】 Describes the electronic distribution in σ-phase of Fe- V alloys andanalyze the bond strength between atoms. The result indicates thatthe reason why the σ- phase embrittlement occurs is mainly the clash-ing avalanche in bond network, and the σ-phase magnetism of Fe -Valloys takes its source at the 3d- orbital magnetic electrons of Fe atoms.更多还原
