2013年5月1日 · B2-type CuZr phase is a ductile intermetallic phase which is beneficial to the excellent plasticity of CuZr-based bulk metallic glass (BMG) composites. Studying the crystallization process of CuZr-based BMGs will be helpful in understanding the forming mechanisms of CuZr phase.

2024年8月1日 · Comparison of phase transformation behavior and mechanical properties of CuZr single crystal using five typical potentials. Comparison with experimental results suggested that B2 phase is softer than the martensite phase. Only Mendelev-2019 and Cheng-2009 show that the martensite phase is stiffer and stronger than the austenite phase.

2017年11月5日 · CuZr-based bulk-metallic-glass (BMG) composites reinforced by a B2-type CuZr crystalline-phase (CP) have been widely studied, and exhibit that the plastic deformation of the CP induces martensitic transformation from the B2 to B19′, which plays a dominant role in the deformation behavior and mechanical properties.

2024年12月11日 · B2-CuZr phase reinforced amorphous alloy matrix composites has become one of the research hotspots in the field of materials science due to the “transformation-induced plasticity” phenomenon, which makes the composites show better macroscopic plastic deformability and obvious work-hardening behavior compared to the conventional amorphous ...

被Cr 原子和Zr 原子(或Mg 原子)占据� 其亚胞的电子衍射谱如图 2(f)所示。BATRA 等 [2−3] 则认 为此析出相为 B2(CsCl 型)有序结 构。本文作者认为考虑到以上所述的 Heusler 相的各 原 子的占位情

The study examined the diffusion mitigation effect and mechanical properties of the Nb interlayer prepared by magnetron sputtering as a CrZr diffusion barrier through annealing experiment, high-temperature air oxidation experiment and ring compression tests.

2020年10月1日 · In this paper, CuCr–Zr alloys prepared by vacuum melting with adding La and Ni elementswere heat-treated and aged, followed by plastic deformation using low-energy cyclic impact tests, to simultaneously improve their mechanical and electrical properties.

摘要： 利用同步辐射X射线衍射方法，研究了金刚石对顶砧中碳化锆（ZrC）的状态方程和结构相变，通过密度泛函理论（DFT）计算了该材料的高压压缩行为.结果表明：ZrC在压强为10.3 GPa时，发生拓扑相变；在压强为13.7 GPa时，相变结束.此外，ZrC立方相的体弹模量为158.6（8.6）GPa，相变后的结构体弹模量为233.8（8.8）GPa. 关键词：...

2024年9月30日 · Three types of EHEA coatings were achieved through the adjustment of the Cr and Zr element proportions on Ti-6Al-4V alloy by laser cladding. The microstructure was eutectic structure composed of Laves and BCC/B2 phases with superlattice structure.

2017年8月21日 · 研究结果表明：cu—Cr-zr合金经950℃×1．5h固溶处理、450oC时效6h硬度达 峰值；此时样品中除早期的具有花瓣状应变场衬度的共格析出相外，另一类强化相为圆盘状形貌 …
