摘要

本文研究了原子有序Cu3Pd合金在室温和低温下的严重塑性变形(SPDs)及其后续退火的力学结构特征。采用透射电镜(TEM)和扫描电镜(SEM)、x射线衍射(XRD)分析和显微硬度测试等研究方法。在室温、低温和后续退火条件下，比较了制备的Cu3Pd合金的力学性能。在低温变形后的再结晶退火过程中，发现了原子有序动力学的显著加速，从而有效的扩散。该方法可用于合成高强度纳米结构电阻性和电接触材料。

Deformation-thermal method for atomic ordering and mechanical improvement of Cu3Pd alloys

The paper presents studies of the mechano-structural characteristics of the atomically ordered Cu3Pd alloy subjected to severe plastic deformations (SPDs) at room and cryogenic temperatures combined with subsequent annealings. Transmission and scanning electron microscopy (TEM and SEM), X-Ray diffraction (XRD) analysis and microhardness tests were used as research methods. The mechanical characteristics of the synthesized Cu3Pd alloy were compared after preliminary SPDs at room and cryogenic temperatures as well as during subsequent annealings. The significant acceleration of the atomic ordering kinetics and, consequently, effective diffusion during recrystallization annealing after cryodeformation was found. The developed deformation-thermal method can be used to synthesize high-strength nanostructured resistive and electrocontact materials.
