【摘要】 利用扩散偶技术和合金法测定了Fe-Mn-Al三元系1000和1100℃等温截面的Fe-Mn侧的相平衡关系,结果表明1000℃有一(α+y+β)三相区,此外,固/气扩散偶被用来测定相平衡成分,表明这种方法对于具有挥发性组元的体系是可行的。更多还原

【Abstract】 Phase equilibria at Fe-Mn side of isothermal section at 1000 and 1100℃ in Fe-Mn-Al system have been determined using the diffusion couple, technique and metallography. A three-phase, α+γ+β, region was found at 1000℃. The method of solid/gas diffusion couple used to determine equilibrium phase composition is believed to be feasible for the system containing volatile component.更多还原
