Strength design of Zr_(x)Ti_(x)Hf_(x)Nb_(x)Mo_(x) alloys based on empirical electron theory of solids and molecules

In this paper, the valence electron structure parameters of Zr_(x)Ti_(x)Hf_(x)Nb_(x)Mo_(x) alloys were calculated based on the empirical electron theory of solids and molecules (EET), and their performance through these parameters were predicted. Subsequently, the alloys with special valence electron structure parameters were prepared byarc melting. The hardness and high-temperature mechanical properties were analyzed to verify the prediction. Research shows that the influence of shared electron number n_A on the strongest bond determines the strength of these alloys and the experiments are consistent with the theoretical prediction.
