Abstract
A novel mechanism for the generation of device materials with very high domain boundary densities is described: we shear the sample in a computer experiment and achieve higher twin densities than in rapid quench. These domain patterns are very stable. Elastically soft materials (image with 6.4$ \times $10(5) atoms) has greater twin densities than hard materials, even for nano-crystals.
摘要
一种生成具有极高畴界密度的器件材料的新机制被描述
我们在计算机实验中对样品进行剪切，从而获得比快速淬火更高的孪晶密度。这些畴图案非常稳定。与硬材料相比，弹性软材料（包含 6.4×10(5)个原子的图像）具有更高的孪晶密度，即使对于纳米晶体也是如此。
