This work aims to describe the mechanism of intermediary phases formation in TiAl20 (wt. %) alloy composition during reactive sintering. The reaction between titanium and aluminum powders was studied by in situ diffraction and the results were confirmed by annealing at various temperatures. It was found that the Ti2Al5 phase formed preferentially and its formation was detected at 400 °C. So far, this phase has never been found in this alloy composition during reactive sintering processes. Subsequently, the Ti2Al5 phase reacted with the titanium, and the formation of the major phase, Ti3Al, was accompanied by the minor phase, TiAl. Equations of the proposed reactions are presented in this paper and their thermodynamic and kinetic feasibility are supported by Gibbs energies of reaction and reaction enthalpies.

Near‐net shaping hot isostatic pressing (NNS‐HIP) forming process has the advantage of high material utilization ratio and good uniformity of billet microstructure. It is widely used to produce critical parts for harsh service environments in special fields such as aerospace and energy and chemical industry. This paper introduces the process characteristics and production flow of hot isostatic near‐net forming, the representative materials of hot isostatic near‐net forming, the development and application at home and abroad, and the micro‐ and macromodels of numerical simulation powder densification by HIP near‐net forming. Finally, the challenges and development trends of this technology are prospected, and corresponding countermeasures are put forward.
