摘要: 本文用透射电子显微镜研究了时效温度、时间和冷变形对淬火后的Cu-20Ni-20Mn合金时效析出相的影响.结果表明时效温室影响析出相形核的位置、形貌和大小.高于400℃时效能抑制品界择优析出,并且使析出相细小和球状化.冷变形也能有效地抑制晶界择优析出,改变析出相的分布,形貌和大小,增加变形量可使析出相细小而均匀地分布于晶内.
Abstract:The effect of either the temperature and time of aging tests or the cold de-formation on the phase precipitated along grain boundaries in Cu-20Ni-20Mn alloywas investigated under TEM observation.The results showed that the aging tempe-rature influences the situation,shape and size of the nucleation of phase precipi-tated.At the aging temperature over 400℃,its preferred precipitation along grainboundary is retarded and the precipitated phase becomes fine and spheroidized.The cold deformation may also retard its preferred precipitation along grain boun-dary and change its distribution,shape and size.The increase of deformation mayimpel the precipitated phase to distribute within the grain more finely and homo-geneously.At all aging test temperatures except 500℃,the fcc solid solution de-composes and the precipitation is NiMn phase of fct structure with lattice constantα_0=0.364 and c_0=0.363 nm.
