The interrupted aging mechanisms were applied to Ni_(75)Al_(2.9)V_(22.1) alloy by using the microscopic phase-field simulation method.For the single phase region existing at high temperature,the low content alloy was used as the study object.With the progressive aging mechanisms,the metastable phaseγ’ of high temperature can be obtained from the low temperature two phase regions,and the quantity ofγ’ phase reduces with increasing temperature.Theθsingle phase morphology at high temperature regions will turn to be theγ’+θtwo phase morphology at low temperature with the interrupted aging method.Despite of the different precipitation paths ofγ’ phase,the precipitation mechanisms are the same for the low temperature aging and high temperature interrupted aging. The measurement of the aging aging mechanisms were applied to Ni_ (75) Al_ (2.9) V_ (22.1) alloy by using the microscopic phase-field simulation method. For the single phase region existing at high temperature, the low content alloy was used as the study object .With the progressive aging mechanisms, the metastable phase γ ’of high temperature can be obtained from the low temperature two phase regions, and the quantity of γ’ phase reduces with increasing temperature. The θsingle phase morphology at high temperature regions will turn to be the γ ’+ θtwo phase morphology at low temperature with the interrupted aging method. Ideally of the different precipitation paths of γ ’phase, the precipitation mechanisms are the same for the low temperature aging and high temperature interrupted aging.
