By means of the X-ray diffraction technique, variations of the lattice parameters of these two nanophases with the grain size were determined. It was found that the values of the lattice parameters for the two nanophases obviously deviated from the equilibrium data for the corresponding perfect crystals. Analysis of the experimental results indicated that the P concentration in the Ni(P) solution nanophase was much enhanced, being about 10－1 5 times as much as the equilibrium solubility, and a highly supersaturated Ni(P)solid solution formed in the nanophase samples. For the Ni_3P nanophase, an evident lattice distortion was detected, and the lattice distortion of the Ni_3P nanophase increases with a reduction in grain size, which might be oringinated from an enhancement of the vacancies in the nanometer-sized crystallites. Key words： nanocrystalline materials    crystallization method    highly supersaturated solid solution. lattice distortion      基金资助:国家自然科学基金;;中国科学院院长特别基金 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 隋曼龄 卢柯 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1994/V30/I21/413 1GleiterH．ProgMaterSci,1989,33:2232SiegelRW．In:FujitaFEed．,PhysicsofNewMaterials,Springer-Verlag:Heidelberg,19923LuK,WangJT,WeiWD．JApplPhys,1991:69:522;ScrMetallMater．1990:24:23194SuiML,LuK,HeYZ．PhilosMag,1991:B63:9335DonnayJDH,OndikHMeds．,CrystalDataDeterminativeTables(3rdEd),NBSJCPDS,1973;26LuK,LuckR,PredelB．ZMetallkd,1993;48:7407CahnRW,HaasenP．PhyscalMetallurgy(3rdEd),Amsterdam:ElsevierSciPubl,1983:9808MutscheleT,KirchheimR．ScriplaMetall,1987;2l:2819HahnH,HoflerHJ,AverbackRS．Proc．DIMETA-88,198810TakamuraJ-I．In:CahnRWed．,PhyscalMetaliurgy,Amsterdam:North-Holland,1965:68111LuiXD,LuK,HuZQ．NanostructuredMater,1993:2:58112董振富,卢柯,魏文铎．金属学报,1993:印刷中13GaffetE,HarmelinM．JLess-commMetals,1991:157:201z [1] 杨勇, 赫全锋. 高熵合金中的晶格畸变[J]. 金属学报, 2021, 57(4): 385-392.
