随着对Ti-Al基金属化合物研究的深入,目前得到的大家比较公认的Ti-Al二元相图如图1所示[3]: 图1 Ti-Al二元相图 Fig.1 Ti-Al binary phase diagram 由图1可知:Ti-Al系中的主要金属间化合物相有:Ti3Al相(α2),γ-TiAl相,δ-TiAl3相。Ti3Al相(α2)具有D019的超点阵结构,密排六方,空间群为P63/mmc α...
本文应用CALPHAD (CALculation of PHAseDiagram,计算相图)方法建立了Ti-Al-Fe-V四元系的热力学数据库。同时,提出了CALPHAD和Mo当量相结合的钛合金设计方法,并设计了三种钛合金:α型(Ti-6Al-3.5V-1Fe)、α+β型(Ti-3Al-22.75V-6.5Fe) 和β型(Ti-4.5Al-10.5V-3Fe)钛合金。
An isothermal section in Ti–Al–V system at 1300 °C is established. • The α single phase region is in substantial enlargement at elevated temperature which has not been reported in this system. • Abundant experimental statistics possibly provided for modeling are obtained. ...
The isothermal section of the phase diagram of the Al-Ti-Er ternary system at 500°C has been determined mainly by X-ray deffraction techniques and the aid of differential thermal analysis, electron probe microanalyses, and metallography. The existence of nine binary compounds and two ternary p...
