A Model for Creep and Creep Damage in the γ-Titanium Aluminide Ti-45Al-2Mn-2Nb [PDF]

, 2014
Gamma titanium aluminides (γ-TiAl) display significantly improved high temperature mechanical properties over conventional titanium alloys. Due to their low densities, these alloys are increasingly becoming strong candidates to replace nickel-base ...

On the Bauschinger effect in TiAl alloys [PDF]

Acta 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.

Aluminium evaporation during ceramic crucible induction melting of titanium aluminides [PDF]

, 2013
Melting TiAl based alloys in ceramic crucibles often leads to chemical contamination, alloy heterogeneity and non-metallic inclusions. The severity of such phenomena usually depends on the nature of crucible materials, the melting stock composition and ...

Interatomic potentials for atomistic simulations of the Ti-Al system [PDF]

, 2003
Semi-empirical interatomic potentials have been developed for Al, alpha-Ti, and gamma-TiAl within the embedded atomic method (EAM) by fitting to a large database of experimental as well as ab-initio data.

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

Advanced Engineering Materials, EarlyView.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...
