In the present work, the role of latent hardening on texture evolution at large strains is examined by embedding the latent hardening interaction matrix in the visco-plastic self-consistent framework. All possible interactions between different slip systems are allowed by specifying the 12 × 12 interaction matrix which consists of the relative strength of different dislocation junctions. In particular, the role of colinear junction which is the strongest among all dislocation locks on texture evolution is highlighted. It was observed that texture simulations in the latent hardening mode with a strong colinear lock provided excellent agreement with the experimentally measured textures, whereas isotropic hardening mode (12 × 12-unit matrix) failed to reproduce the experimental textures in a satisfactory manner.

在目前的工作中，通过将潜在硬化相互作用矩阵嵌入粘塑性自洽框架中，研究了潜在硬化对大应变下织构演变的作用。通过指定由不同位错结的相对强度组成的 12 × 12 相互作用矩阵，允许不同滑移系统之间的所有可能相互作用。特别是，在所有位错锁中，共线结对纹理演化的作用最为突出。观察到具有强共线锁的潜在硬化模式下的纹理模拟与实验测量的纹理非常吻合，而各向同性硬化模式（12×12-单位矩阵）未能以令人满意的方式再现实验纹理。
