The effect of electropulsing on the corrosion cracking titanium aluminide produced by self-propagating high-temperature synthesis has been investigated. treatment led to improved resistance in sodium fluoride solution and also eliminated at α2/γ interface during a nitric hydrofluoric acids. This behavior was attributed thermal athermal effects resulting from leading interaction conduction elect...

Abstract Crack formation process in the Ti-23Al-23Nb-1.4V-0.8Zr-0.4Mo-0.4Si (at.%) alloy based on orthorhombic titanium aluminide (Ti 2 AlNb), especially weld zone (WZ), heat-affected (HAZ), and base metal (BM), during laser beam welding (LBW) at room temperature was considered. It determined that crack spread WZ throughout crystallites of ?-phase. In HAZ, cracks globular ?-phase crystals body ...

Titanium alloys are widely used as construction materials in the aerospace and automotive industries. They have many advantages but also limitations related to their susceptibility high-temperature oxidation hot corrosion. Many efforts increase lifetime of components made titanium been reported literature; most promising ones involve deposition coatings. The present paper is focused on developm...

Combustion synthesis is a special thermophysico-chemical process applied for production of intermetallic compounds. In the present work, a reaction–diffusion numerical model was developed to analyze the combustion synthesis of aluminide intermetallics by self-propagating high-temperature synthesis process. In order to verify the reliability of the numerical model, an experimental setup was desi...
