用 X-射线衍射仪测定了 Fe-Mn-C 奥氏体固溶 Al,Cr,Si 后的点阵参数。实验结果表明,Fe-Mn-C 奥氏体的点阵参数随 Al 或 Cr 固溶量的增加线性增大,随 Si 固溶量的增加线性减小。
The lattice parameters of Fe-Mn-C austenite in solution of Al, Cr and Si were measured by X-ray diffraction. The experimental results show that the lattice parameters of Fe-Mn-C austenite increase linearly with the increase of the solid solution amount of Al or Cr and decrease linearly with the increase of the solid solution amount of Si.
