根据对细小全层片组织及其高温转变中间组织的金相和电镜观察分析结果，提出了一种新的双相钛铝合金全层片组织形成机理，即γ／α层片结构在α单相区温度下沿γ相基体中不同取向｛111｝γ惯习面成束形成，而后在冷却过程中转变为层片团细小的γ／α2全层片组织.
According to the results of microstructure and electron microscopy analysis of the microstructure of the microstructure and the intermediate structure of the high temperature transition, a new mechanism of full-thickness titanium double-phase aluminum alloy is proposed, that is, Phase zone temperature along the γ-phase matrix in different orientation {111} γ habitual surface into bundles, and then cooled during the transformation into small layers of γ / α2 full-thickness tissue.
