It is shown that the microhardness increases systematically upon increasing the concentration of Co or Ni. The effect of structural relaxation on the microhardness has been investigated for Zr_(78) Co_(22) and Zr_(75.9)Ni_(24.1). The microhardness exihibits a minimum and, then, increases slowly during isothermal annealing at 250℃. For isochronous annealing at differe nt temperature the microhardness increases very sharply when the crystallization temperature is approached. Complementary experimental results of DSC, resistivity, superconducting-critical-temperature and X-ray-diffraction measurements are used for an analysis of the phenomena occurring during structural relaxation and crystallization. 收稿日期: 1986-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张其瑞 H.C.Freyhardt 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I4/125 1 Chen, H.C., J.
