Molecular Dynamics Simulation of the Tensile Deformation Behavior of the γ(TiAl)/α2(Ti3Al) Interface at Different Temperatures

Compression and fretting wear studies of γ/α 2 duplex TiAl alloys at the nanoscale

“…The results showed that the presence of RT layered interfaces led to the accumulation of dislocations, local stress concentration, and grain refinement to some extent, which improved the material properties and enhanced the wear resistance of the alloy. Liu et al [28] found in their research that γ/α 2 The interface plays a dominant role in the tensile deformation process and improving the strength of TiAl alloys at different temperatures, and increases with temperature γ/α 2 The semi-coherent interface plays a more significant strengthening role in the deformation process compared to the cohesive interface. Wen et al [29] investigated the micromotional wear mechanism of γ-TiAl alloy substrates with and without the introduction of RT lamellae and found that the introduction of the RT interface limited the downward motion of the abrasive grains and that the normal force of the abrasive grains increased with the increase in the thickness of the RT lamellae.…”
