1. The electron theory on metals will be further progressed and be widely adopted in alloy materials developments.

2. The results of the empirical electron theory of Fe-Cr bcc disordered solid solutions are reported.

3. Thus in the depth of the valence electron theory of solid solution the mechanical behavior of the alloy elements in martensite was shown.

4. This paper discusses defect of interpretation of metal conduction's classical electron theory, and analysis factors of contradiction.

5. Based on the collection of the related information , the applications of the metal electron theory to the specific alloy material researching are described and analyzed.

6. The isochromatization of the associated reaction and the solvent effect were discussed by the electron theory with the absorption spectrum and energy diagram.

7. It eliminated the contradiction between Einstein gravitational theory and Dirac electron theory.

8. As the development of physics and chemistry as well as the advanced measuring techniques, a great progress of the electron theory on metal is made and is applied to alloy material investigation.
