摘要

摘要与先前重复报道的分布在α-Zr基体内的片状面心立方锆（FCC Zr）不同，分散的纳米级FCC Zr具有晶格参数a = 0.520 透射电子显微镜（TEM）在ω-Zr片层状和块状内部发现了nm。FCC Zr与ω-Zr的取向关系服从[001]FCC//[1 02]ω，（100）FCC//（110）ω。讨论了FCC Zr、α-Zr和β-Zr之间可能的相变机制。这一发现为锆合金制造过程中的相变提供了一种新的可能性，可能对新型高性能锆合金的设计有所启发。

Nanoscale face-centered-cubic zirconium dispersed in omega zirconium

ABSTRACT In contrast to lamella-like face-centered cubic zirconium (FCC-Zr) distributed inside an α-Zr matrix, as repeatedly reported previously, dispersed and nanoscale FCC-Zr with lattice parameter a = 0.520 nm has been found inside lamella-like and blocky ω-Zr by transmission electron microscopy (TEM). The orientation relationship between the FCC-Zr and the ω-Zr obeys [001]FCC//[1 02]ω, (100)FCC//(11 0)ω. A possible phase transformation mechanism between FCC-Zr, α-Zr and β-Zr is discussed. This finding introduces a new possibility in phase transformations during the fabrication of Zr alloys, potentially enlightening the design of new high-performance Zr alloys.

期刊介绍： Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate. Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
