In this paper, we have made a theoretical study about the structure and energy of stacking fault and anti-phase boundary of metals and alloys by using the embedded atom method ( EAM ). 在本文中我们将采用嵌入原子法理论就FCC金属和合金的层错与反相畴界的结构和能量进行理论的研究。
Therefore, a systemic study of the structure and energy of stacking fault and anti-phase boundary of FCC metals and alloys will provide theoretical foundation and introduction for the mastery and transforming of material properties and designing new materials. 因此,系统的研究FCC金属及合金中的层错与反相畴界的结构和能量将为掌握材料性质、实现材料改性和设计新材料提供理论基础和指导。
And anti-phase boundary energy is an important factor in a alloy material's resistance to deformation, and also affects the way deformation occurs. 反相畴界能则在合金材料的抗形变过程中起了重要作用,并会影响合金发生形变时的途径。
A Theoretical Study about the Stacking Fault and Anti-phase Boundary in FCC Metals and Alloys FCC金属及合金的层错及反相畴界的理论分析
The experimental results show that the addition of trace Mg to the alloy will increase greatly the DLRO and the anti-phase domain boundary energy of γ′ - phase. As a result, the resistance provided by γ′ - phase to the dislocation movement can be increased. 实验结果表明,微量Mg的加入能够明显提高γ′相的长程有序度和反相畴界能,因而有效地增加了γ′对位错运动的阻力。
