The present work illustrates the effect of quasi-hydrostatic pressure on the positions and widths of the homogeneity ranges of the intermetallic phases TiFe and TiFe₂ at high temperatures. The experiments were performed with Ti–Fe diffusion couples that were heat treated in a multi-anvil press at 2.5 GPa. The solubility limits of the phases were derived from the concentration profiles that were measured using electron probe microanalysis. It was found that the homogeneity ranges of TiFe and TiFe₂ extend to higher titanium concentrations, if the pressure is applied. The positions of the phase boundaries of the intermetallics on the iron-rich side are not affected by the pressure. The accuracy of the experimental data including the homogeneity ranges and temperatures was verified by comparing the homogeneity ranges of β-Ti(Fe), α/δ-Fe(Ti) and γ-Fe measured in this study with the homogeneity ranges taken from literature. The pressure was calibrated using the pressure-induced phase transitions of bismuth.

目前的工作说明了准流体静压力对高温下金属间相 TiFe 和 TiFe ₂的均匀范围的位置和宽度的影响。实验是用 Ti-Fe 扩散偶进行的，这些扩散偶在多砧压力机中以 2.5 GPa 进行热处理。相的溶解度极限来自使用电子探针微量分析测量的浓度分布。发现 TiFe 和 TiFe ₂的均质范围如果施加压力，则扩展到更高的钛浓度。富铁侧金属间化合物的相界位置不受压力影响。通过将本研究中测得的β-Ti(Fe)、α/δ-Fe(Ti)和γ-Fe的均一范围与文献中的均一范围进行比较，验证了包括均一范围和温度在内的实验数据的准确性. 使用压力诱导的铋相变校准压力。
