Abstract:The effect of aging treatment on residual resistance ration of pure beryllium was studied by the use of electric potential approach. The results show that the residual resistance ration relates not only to the aging temperature and the impurity concentration of the metal, but also to the aging time. Residual resistance ration is improved with the increase of beryllium purity. The residual resistance ration value of pure beryllium is 20−147, and it changes with the aging temperature and aging time. High pure beryllium has ageing tendency just as alloy, so it can be used as aging low alloy to investigate the effect of impurity on the metal performance.
Key words: beryllium; residual resistance ration; aging treatment
