摘要
在 333 K 和 448 K 下用 1.5 MeV 电子辐照铜-1.2%铁样品。相反，辐照对维氏硬度的影响很小。实验结果被解释为是由于辐射增强扩散产生了富含铁的小团簇。本研究表明，电子辐照可精细控制铜铁合金的磁性和电性。
Effects of energetic electron irradiation on electric, magnetic, and mechanical properties of Cu-1.2 at.%Fe alloy
Cu-1.2 at.% Fe samples were irradiated with 1.5 MeV electrons at 333 K and 448 K. Effects of the irradiation were observed as an increase in electrical conductivity and magnetization. In contrast, the Vickers hardness was little changed by the irradiation. The experimental results were explained as due to small Fe-rich clusters produced through radiation-enhanced diffusion. The present study shows that electron irradiation provides a fine control of the magnetic and electric properties of the Cu-Fe alloy.
期刊介绍：
Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
