2012年4月1日 · X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to analyse the α-Ti phase in both as-sintered and as-cast α-Ti materials. The structure factor of the (0001) plane of the α-Ti phase is 0.

2017年11月1日 · Here we show that small FCC precipitates form in freestanding thin foils during in situ transmission electron microscope (TEM) heating and we discuss the potential origins of the FCC phase in light of the in situ observations.

2024年9月24日 · Here, by using in situ transmission electron microscopy (TEM), we uncover direct evidences on the nucleation and growth of FCC-Ti right in front of the crack tip in the α-Ti matrix. Atomic resolution images further reveal that the transformation can be mediated by either partial dislocations on basal planes or shear and atomic shuffle on the ...

2018年8月1日 · Phase transformation process of interfacial Ti precipitates in Nb-Ti-Si based alloys is systematically investigated by in-situ transmission electron microscopy (TEM) observation. The Ti precipitates exhibit an uncommon face-centered cubic (fcc) structure, which can be identified by analyzing its chemical composition and phase transformation ...

2012年4月1日 · hcp 结构的 alpha-Ti 是两种基本相（alpha-Ti 和 beta-Ti）材料之一。 X 射线衍射 (XRD) 和透射电子显微镜 (TEM) 用于分析烧结态和铸态 α-Ti 材料中的 α-Ti 相。 α-Ti 相的 (0001) 面的结构因子为 0。

2021年7月7日 · 通过透射电子显微镜 (TEM) 观察研究了压缩试验期间 Ti-15Mo 合金中 ω 析出物的机械响应。 钛合金因其高比强度和良好的生物相容性而成为结构和生物医学应用中不可或缺的材料 [1] 。

2016年10月21日 · The Ti/Al multilayers of nominal periods = 50 nm and = 200 nm were deposited using double target magnetron system equipped with rotating substrate holder. The in situ TEM experiments were aimed at explaining DSC measured exothermic effects through phase transformations taking place during heating of the multilayers with small and large period.

Titanium sesquioxide (Ti2O3) is drawing broad attention due to its fascinating physical properties and promising applications in the fields of energy, biomedicine, and...

2025年1月6日 · Transmission electron microscopy (TEM) is an indispensable tool for elucidating the intrinsic atomic structures of materials and provides deep insights into defect dynamics, phase transitions, and nanoscale structural details.

在这里，我们展示了在原位透射电子显微镜 (TEM) 加热过程中在独立的薄箔中形成了小的 FCC 沉淀物，并且我们根据原位观察讨论了 FCC 相的潜在起源。 发现这种 FCC 相在冷却和环境条件下是稳定的，这使我们能够通过纳米机械原位 TEM 测试探索其机械性能和稳定性。 摘要 纯钛传统上在环境条件下呈现六方密堆积 (HCP) 晶体结构，在高温下呈现体心立方 (BCC) 结构。 除了 Ti 合金的这些典型结构外，偶尔还报告了与薄膜、界面或高水平塑性变形相关的面心立方 (FCC) 相 …
