引言离子晶格能的计算方法在教课书中是早已成型了的〔1〕,在已建立起的完整晶格能的计算方法的基础上,已得到相互作用能曲线,又由它可以计算出相互作用力,从而解释了一些现象,包括完整晶体的一些力学行为.本文要学习的问题,是由相互作用的角度来解决细粒多晶金属在均向压力或均向张力作用下的一切力学性质.至于离子晶格能的计算方法不能够原封不动地用于实际的多晶金属,细粒多晶金属一般视为是各向同性,而离子晶体的离子键是球对称的.因此本文作的分析,在性质上有些象离子晶体晶格能问题,但与此又大有区别:
Introduction The calculation method of ionic lattice energy is already formed in the textbook [1]. Based on the established calculation method of the complete lattice energy, the interaction energy curve has been obtained, and it can be calculated Out of the interaction force, which explains some of the phenomena, including some of the mechanical behavior of the complete crystal.The problem to be studied in this paper is to solve all the problems of the fine-grained polycrystalline metal under the action of uniform or uniform tension from the perspective of interaction Mechanical properties.As for the calculation of ion lattice energy can not be used intact for the actual polycrystalline metal, fine-grained polycrystalline metal is generally considered isotropic, and ionic crystal ionic bonds are spherical symmetry.Therefore The analysis made in this paper, in nature, is somewhat like the crystal lattice energy of ionic crystals, but it is quite different from this:
