  高压扭转诱导 TiPt 高温形状记忆合金的结构变化

  摘要：

  使用同步辐射实验和透射电子显微镜研究了高压扭转 (HPT) 诱导的 TiPt 高温形状记忆合金的微观结构。在剧烈塑性变形后，母体 B19 马氏体被强烈细化和高度应变。虽然既没有遇到强烈的化学无序也没有遇到非晶化，但观察到晶体反射的发生，这可以根据 L1 0相和长程有序堆叠结构进行索引。L1 0的出现阶段可能由高静水应力以及 HPT 期间叠加的剪切应力触发。TiPt 的奥氏体和马氏体开始和结束温度不受 HPT 的影响，因为在加热时，再结晶发生在反向马氏体向奥氏体转变开始之前。

  Equiatomic platinum-titanium powder mixtures were processed by high energy ball milling under argon atmosphere and sintered under vacuum. Evolution of the crystal structures and microstructures of the products formed were investigated by XRD and SEM techniques, respectively. The HCP crystals of Ti were first deformed and then a disordered metastable FCC Pt(Ti) solid solution was formed during milling due to semi-coherency of FCC lattices. A nanostructured Pt(Ti) product was formed after long milling time, which contained 44-47 at.% Ti and 53-56 at.% Pt.An ordered PtTi intermetallic was formed by annealing the metastable Pt(Ti) at temperature above 1300 degrees C. The crystal structure and microstructure of the TiPt phase depended on the milling time, annealing temperature and the cooling rate. The B19 PtTi plate martensite was formed after annealing at 1500 degrees C and quenching at a cooling rate of 23 degrees C/min to 200 degrees C/min for short time milled products. The width of martensite features was smaller at high cooling rate. In PtTi products milled for longer time, no martensitic transformation was observed on cooling the annealed samples. Small amounts of Pt5Ti3 were formed in the powders milled for 16 h or more, followed by annealing at 1500 degrees C and furnace cooling at similar to 2 degrees C/min. (C) 2012 Elsevier B. V.

  Alloys of the Ti-Pt system between 30 and 61 at.% Pt were studied using metallography with optical and scanning electron microscopy (SEM), X-ray diffraction (XRD), and differential thermal analysis (DTA). A phase of nominal composition Ti4Pt3, in the range 41.7-43.4 at.% Pt was found in samples containing between 30 and 47 at.% Pt, and was apparently formed by a peritectoid reaction between beta-TiPt and Ti3Pt at 1205+/-10 degreesC. The eutectic reaction between Ti3Pt and beta-TiPt was found to be at similar to35 at.% Pt and 1424+/-10degreesC, and the Ti3Pt phase melted at circa 1500degreesC. The other phase boundaries agreed with the published literature, except that a slightly wider range was found at 1200degreesC for beta-TiPt. (C) 2004 Elsevier B.V. All rights reserved.

  The microstructure of a TiPt high temperature shape memory alloy induced by high pressure torsion (HPT) was studied using synchrotron radiation experiments and transmission electron microscopy. Upon the severe plastic deformation, the parent B19 martensite is strongly refined and highly strained. While neither strong chemical disorder nor amorphization are encountered, the occurrence of crystal reflections
