Research Progress of Crystal Plasticity Mechanics Model in Texture Evolution of Magnesium Alloy

Keywords： magnesium alloy , crystal plasticity mechanics , texture evolution , numerical simulation

晶体塑性力学建立于位错理论,能够将材料的塑性变形行为和微观组织变化联系起来,被广泛应用于形变织构的研究中.简述了镁合金的塑性变形机制,介绍了晶体塑性力学在镁合金织构演化模拟中的应用发展过程,重点对泰勒模型、弹塑性自洽模型、粘塑性自洽模型、弹粘塑性自洽模型的研究过程及其应用现状进行了综述.最后指出了晶体塑性力学模型在镁合金织构演化应用中存在的问题,并展望了其在镁合金变形织构模拟中的应用前景.
