摘要

用透射电镜研究了在Zr-2.5Nb压力管中析出的氢化物的习惯面。结果表明，在α- zr晶体的不同取向上，微观氢化物的痕迹表明其习惯面接近{101 4}α。这种类型的习惯面对应于沉淀过程早期“初级”氢化物板的形成。根据目前的结果，讨论了文献中关于氢化物习惯面的差异。

Some observations on the habit plane of hydride plates precipitated in Zr-2.5Nb pressure tubes

The habit plane of hydrides precipitated in a Zr-2.5Nb pressure tube has been studied through transmission electron microscopy. Results showed that the trace of the microscopic hydride, as seen on different orientations of the α-Zr crystal, indicates a habit plane close to

{1 0 \overline{1} 4} α

. This type of habit plane corresponds to the formation of “primary” hydride plates during the early stage of the precipitation process. In light of the present results, the discrepancies found in the literature concerning the habit plane of hydrides have been discussed.

期刊介绍： The Journal of Nuclear Materials publishes high quality papers in materials research for nuclear applications, primarily fission reactors, fusion reactors, and similar environments including radiation areas of charged particle accelerators. Both original research and critical review papers covering experimental, theoretical, and computational aspects of either fundamental or applied nature are welcome. The breadth of the field is such that a wide range of processes and properties in the field of materials science and engineering is of interest to the readership, spanning atom-scale processes, microstructures, thermodynamics, mechanical properties, physical properties, and corrosion, for example. Topics covered by JNM Fission reactor materials, including fuels, cladding, core structures, pressure vessels, coolant interactions with materials, moderator and control components, fission product behavior. Materials aspects of the entire fuel cycle. Materials aspects of the actinides and their compounds. Performance of nuclear waste materials; materials aspects of the immobilization of wastes. Fusion reactor materials, including first walls, blankets, insulators and magnets. Neutron and charged particle radiation effects in materials, including defects, transmutations, microstructures, phase changes and macroscopic properties. Interaction of plasmas, ion beams, electron beams and electromagnetic radiation with materials relevant to nuclear systems.
