摘　　要：A methodological innovation in the study of crystal vacancies comes from Schaefer et al . Their technique allows contact free measurements as a function of time, up to high temperature and without contamination. It apppears that the approach of schaefer could be used directly measure vacancy concentration after various heat treatments and then could help check the George Baleer theory of anomalous yield stress in FeAl.A methodological innovation in the study of crystal vacancies comes from Schaefer et al .
