  通过迭代法从 Ti/Zr 基块状金属玻璃开发 β 型块状金属玻璃复合材料

  摘要：

  摘要 含有原位形成的 β-Ti/Zr 相（β-型 BMGCs）的块状金属玻璃复合材料具有良好的强度和塑性组合，通常通过添加 β-稳定剂，如 Nb、Ta、V、等，转化为 Ti/Zr 基块状金属玻璃 (BMGs)。在这项工作中，提出了一种迭代方法，从 Ti/Zr 基 BMGs 开发 β 型 BMGCs，BMGCs 的组成可以通过“原位形成的 β 相的组成（迭代变量）+ BMG”。由于 β 相和（过冷）液相之间的快速元素扩散，迭代方法可以开发 β 型 BMGC，其中两相在凝固过程中可以保持相互（亚稳态）平衡。讨论了迭代方法的程序及其基本的热力学和动力学原理，并且使用迭代方法从 Vitreloy 1 开发了 Zr56.9Ti18.8Cu7.4Ni5.7Be11.3 BMGC。与传统方法开发的β型BMGC相比，迭代法开发的β型BMGC具有两个优点：（i）初始BMG良好的玻璃形成能力可以很大程度上被BMGC中的玻璃基质继承；(ii)

  Abnormal martensitic transformation of high Zr-containing Ti alloys

  摘要：

  Martensitic phases are intermediate phases in Ti alloys and have obvious effects on microstructure and properties of heat treated specimens. The martensitic transformation and phase stability of Ti alloys with high content Zr were investigated. The addition of high content Zr was found to greatly modify the beta phase stability and martensitic transformation of Ti alloys. The beta transus temperature of Ti-50Zr binary alloy is about 616 degrees C. Simultaneously, the phase composition of the beta quenched Ti-50Zr binary alloy is composed of whole alpha' martensitic phase. Reversely, the Ti-30Zr-10Al-3.5V and Ti-50Zr-10Al-3.5V quaternary alloys have the higher beta transus temperatures 779 and 636 degrees C, respectively. However, phase composition is major alpha '' martensitic phase in p quenched Ti-30Zr-10Al-3.5V alloy and is major beta phase in beta quenched Ti-50Zr-10Al-3.5V alloy, respectively. This interesting martensitic transformation phenomenon does not conform to previous wide accepted martensitic transformation theories and laws of Ti alloys. The delayed martensitic transformation of aforementioned two quaternary alloys was considered to be caused by the local stresses resulting from the extra additions of Al and V alloying elements.

  Shine red and yellow photoluminescence in GdAlO3−δ powders

  摘要：

  GdAlO3-delta (delta = 0.0, 0.1 and 0.2) compounds were prepared by the conventional solid-state method. XRD patterns revealed that all samples present a major orthorhombic structure. An intense red and a yellow photoluminescence (PL) emissions were observed at room temperature for delta = 0.0 and delta not equal 0.0 samples, respectively. The red emission was related to the singly ionized oxygen vacancies V-O. The production of doubly ionized oxygen vacancies V-O lead to the appearance of a yellow color observed directly from delta = 0.1 and 0.2 samples. The presence of singly and doubly ionized clusters was found to play an important role in the formation of hole-electron pairs and to give rise to the PL emission. The presence of singly ionized oxygen vacancies was confirmed by the EPR study. (C) 2015 Elsevier B.V. All rights reserved.

  Multilayer structures of ZrB2 containing 30–70 wt% Ti were fabricated using a laser sintering/melting technique. Ti acted as the binding interface for the hard ZrB2 particles. Structural properties and oxidation behavior of laser‐sintered samples were studied using high‐temperature X‐ray diffraction (HTXRD). HTXRD revealed the formation of boride solid solutions (Zr0.61Ti0.39B2, Zr0.2Ti0.8B2), Zr0.3Ti0.7 and TiB whiskers as well as several oxide species (Ti2ZrO and ZrOx) during laser sintering process. Laser‐sintered Ti–ZrB2 mixtures had high relative densities (>92%) and hardness values (up to 11.4 GPa). The reactions enhanced dissolution of ZrB2 into Ti, governing the final compositions of the mixtures and facilitating the production of high‐density boride solid solutions.

  In titanium (Ti) alloys, metastable phases, such as beta and martensite phases, have obvious effects on microstructure and properties of heat treated specimens. The beta phase stability and martensitic transformation of TiZr-based alloys with different Al content were investigated. The addition of Al, the acknowledged alpha stabilizer of Ti-based alloys, is found to greatly modify the beta phase stability and martensitic transformation of TiZr-based alloys. The beta transus temperature of Ti60Zr40 binary alloy is about 640 degrees C. Simultaneously, as Al content increasing, beta transus temperature increases significantly. When Al content reaches 15 at.%, the beta transus temperature increases to nearly 850 degrees C. However, the phase composition of the beta quenched Ti60Zr40 binary alloy is composed of whole alpha' martensitic phase. Reversely, the (Ti60Zr40)(85)Al-15 alloy, which possesses higher beta transus temperatures, is mainly composed of beta phase. This interesting martensitic transformation phenomenon does not conform to previous wide accepted beta stabilizer theories and laws of Ti alloys. The main reasons of the abnormal beta-phase stability in TiZrAl alloys are considered to be high cohesive energy, inherent low beta -> alpha phase transition temperature, and extra local stress.

• Microstructural evolution and twinning behavior of a cold-rolled Zr70Ti30 alloy

  The microstructural evolution and mechanical properties of a Zr70Ti30 alloy subjected to cold rolling were investigated. The microstructural evolution against thickness reduction can be summarized as: equiaxed coarse grains -> dislocation generation and multiplication -> formation of microbands -> formation of twins in microbands -> dislocation-twin boundary interactions. At the early stage of rolling, dislocation slip dominated the plastic behavior until the thickness reduction of rolling reached 20%. Twinning gradually took place and became the major mechanism as the deformation proceeds. The occurrence of twinning would change the orientation of grains, which in turn facilitates subsequent dislocation slip. Three slip systems, including prism, basal and pyramidal, and two types of twinning 10 (1) over bar1} and 10 (1) over bar2} were observed during deformation. The hardness evolution indicates a strain hardening process during cold rolling. (C) 2019 Elsevier B.V. All rights reserved.

  The microstructure, mechanical properties, and fracture characteristics of (Zr50Ti50)(100-x)B-x alloys (x = 0, 0.5, 1, 2 at.%) obtained by casting were investigated. Trace additions of boron (B) to the Zr50Ti50 alloys induced significant microstructural changes. Changes included the promotion of dendritic growth and refinement in prior-beta grain and alpha'-lath size. Large numbers of stacking faults were also observed in ZrB2 and TiB intermetallics. The location of B atoms and the lattice mismatch energy between intermetallics and matrix were responsible for the stacking faults. (ZrTi) B alloys demonstrated higher tensile strength than matrix material. Both the intermetallics with high strength and modulus and the grain refinement played important roles in improving the mechanical properties of alloys. This result could be explained in terms of a shear-lag model based on the load transfer concept and Hall-Petch mechanism. The elongation-to-failure of (ZrTi) B alloys decreased with increased B concentration. The reduction in elongation-to-failure of (ZrTi) B alloys could be attributed to the presence of ZrB2 and TiB intermetallics and refinement of alpha'-laths. (C) 2015 Elsevier B.V.

• Hexagonal close packed to face centered cubic polymorphic transformation in nanocrystalline titanium–zirconium system by mechanical alloying

  The present study reports a reversible hexagonal close packed (hcp) to face centered cubic (fcc) polymorphic phase transformation in four different nanocrystalline titanium-zirconium binary alloys in the course of mechanical alloying in a planetary ball mill. This transformation is monitored at appropriate stages by X-ray diffraction and high-resolution transmission electron microscopy. Lattice parameter of the nanocrystalline fcc phase is a function of the alloy composition. For a given alloy, the lattice parameter and hence volume per atom increase with increase in milling time under comparable conditions. On the other hand, crystallite size, measured from X-ray peak broadening, significantly decreases with the progress of milling. It is suggested that structural instability due to plastic strain, increasing lattice expansion, and negative (from core to boundary) hydrostatic pressure is responsible for this hcp -> fcc polymorphic transformation. The said transformation seems reversible as isothermal annealing at 1000 degrees C for 1 h or melting the powder mass leads to partial or complete transformation of the milled product from single phase fcc to hcp.
