Abstract

ABSTRACT In situ observation of a phase transformation during annealing of Si containing diamond-cubic (dc) and metastable phases has been performed using synchrotron X-ray diffraction. Metastable body-centred-cubic (bc8) and rhombohedral (r8) phases were formed by high-pressure torsion. These metastable phases gradually disappeared when increasing the annealing temperature to ∼ 180°C while another metastable phase having a hexagonal diamond (hd) structure appeared at ∼ 190°C. High-resolution transmission microscopy analysis revealed that hd and dc grains were present after annealing at 200°C. The results indicate that a phase transformation, mainly from bc8 to hd, occurred during annealing.

高压扭转硅退火过程中相变的同步X射线衍射观察
利用同步x射线衍射原位观察了含金刚石立方相(dc)和亚稳相Si在退火过程中的相变。高压扭转形成亚稳体心立方相(bc8)和菱形面体相(r8)。当退火温度提高到~ 180℃时,这些亚稳相逐渐消失,而在~ 190℃时出现另一种具有六边形金刚石(hd)结构的亚稳相。高分辨率透射显微镜分析显示,在200℃退火后,存在hd和dc晶粒。结果表明,在退火过程中发生了以bc8为主的相变。

期刊介绍: Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate. Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
