The panal isothermal sections of the Ti-Al-Cr system and the partial vertical diagram of the Ti-Al system with Cr content smaller than 10% in the temperature range have beed drawn. The results confirmed the rule of the distribution ratio of Cr in α2(α) andγ phases and supported the vieWpoint that Cr occupies Al site and thus reduces Al content in γ-TiAl. Key words:  Ti-Al-Cr ternary system      α_2(α)/γ phase equilibrium      diffusion couple      Received:  18 February 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I2/171 1Kim Y W.JOM, 1989;41(7):24 2Kim Y W.JOM ,1994;46(7):30 3山口正治,乾晴行,并泰治.金属.1995;65:215(Yamaguchi M,Inui H, Shiroi T, Met Technol ,1995; 65:215) 4桥本健纪,土肥春夫,笠原和男,迁本得藏,铃木朝夫.日本金属学会志,1988;52:816(Hashimoto K, Doi H, Hasahara K, Tsujimoto T and Suzuki T.J Jpn Inst Metals, 1998; 52: 816) 5Taylor J L, Duwez P.
