Fracture of convoluted and lamellar α2 + γ TiAl alloys

Andreas Mortensen, Nicolas Vincent Barbi, Frédéric Diologent

Fracture toughness tests are conducted at room temperature and 923 K (650 degrees C) on SENB (Single Edge Notched Bend) specimens of three different (alpha(2) + gamma ) TiAl-based alloys. One alloy is a conventional near fully lamellar Ti-45Al-2Mn-2Nb + 0. ...

Deformation and Fracture Toughness of Two-Phase Titanium Aluminides

Nicolas Vincent Barbi

This thesis is an exploration of deformation and fracture properties of a novel two-phase α2 + γ Ti46Al8Ta (at.%) alloy featuring a "convoluted" microstructure, produced by partners within a European Union project named IMPRESS. Properties of this alloy ar ...

Influence of chemistry and microstructure on the activation volume of TiAl alloys

Andreas Mortensen, Nicolas Vincent Barbi, Luc Rougier, Frédéric Diologent

Repeated stress-relaxation experiments are conducted from RT to 1073 K on three different gamma + alpha(2) TiAl alloys (Ti-46Al with 8Ta, 8Nb or 7Nb) One is a conventional duplex alloy, the two other are novel "convoluted" cast titanium aluminides develope ...

Fracture toughness of TiAl alloys: A comparison of two gamma-a2 structures

Andreas Mortensen, Nicolas Vincent Barbi, Frédéric Diologent

Toughness measurements of a Ti-45Al-2N4u-2Nb + 0.8%vol TiB2 alloy with a. near fully lamellar microstructure and a Ti-46Al-8Nb alloy with a convoluted microstructure are performed at 650 degrees C under vacuum according to ASTM Standard E1820. Respective v ...
