材料物理与材料设计

本文以“固体与分子经验电子理论”和“C-Si偏聚理论”为基础,把材料科学中广泛使用的原子表象理论深入到电子理论,讨论了Fe基材料原子间的价电子结构以及价电子结构造成的C-Me偏聚和C-Me偏聚对相变动力学、组织形态学、材料强韧性的影响等几个材料物理的基本问题,从而为Fe基材料的成份设计提供了理论依据并揭示了用理论设计取代经验设计的可行性。

Matrials Physics and Matrials Design

In this paper, based on the empirical electron theory of solid and molecules and the theory of C-Me segregation, this makes the atomic theory which is applied widely in the matrials science go deep into the electron theory. This paper discusses a few of basic problem of matrials physics: 1. the valence electron structure of atoms of Fe-base matrial 2. C-Me segregation that the valeace electron structure brings about. 3.effect of C-Me segregation on phase transformation kinetics and morphology and matrial strength and toughness. Therefore, these provide theory foundation on the composition design of Fe-base matrial and bring out the possibility that theory design replaces experience design.
