MICROSTRUCTURE AND MECHANICAL CHARACTERISATION OF TIAL COATED ON Ti64

open access: yesSouth African Journal of Industrial Engineering, 2017
In this study, TiAl alloy was coated on Ti64 using a 1074nm high power continuous-wave laser while varying the laser beam scanning speed. This was done in order to increase the thermo-mechanical properties of Ti64.

The Production of TiAl by Foundry Processes [PDF]

open access: yesKey Engineering Materials, 2002
This paper describes a foundry technique that enables the production of TiAl employing an adapted melting procedure that uses an induction furnace with suitable refractory crucibles, inside a controlled atmosphere chamber. The developed technique allows the production of samples with a low and controlled amount of residual elements, with a thin ...

On the Bauschinger effect in TiAl alloys [PDF]

open access: yesActa Materialia, 2016
Abstract The Bauschinger effect has been investigated at room temperature on a multiphase titanium aluminide alloy based on γ(TiAl). The effect of strain reversal was assessed by comparing uni-directional tensile tests with those performed on specimens made from pre-compressed material.

Oxidation Behavior of TiAl-Based Alloy Modified by Double-Glow Plasma Surface Alloying with Cr–Mo

open access: yesHigh Temperature Materials and Processes, 2017
A Cr–Mo alloyed layer was prepared on a TiAl-based alloy using plasma surface alloying technique. The isothermal oxidation kinetics of the untreated and treated samples was examined at 850 °C. The microstructure and phase composition of the alloyed layer

Effect of spark plasma sintering temperature on the multi-scale microstructure evolution and mechanical properties of Ti2AlC/TiAl composites with network architecture

open access: yesJournal of Materials Research and Technology, 2023
In the present work, Ti2AlC/TiAl composites with network architecture were fabricated by the method of spark plasma sintering (SPS) at different temperature using Ti–48Al–2Cr–2Nb pre-alloyed powders and graphene nanosheets (GNSs) as raw materials.
