Intermetallic titanium aluminides based on the ordered γ‐TiAl phase have gained increasing
interest as innovative high‐temperature light‐weight structural materials. They have found …

Boron was found to be a unique grain refiner in cast TiAl alloys in the beginning of 1990s
and has become an element in most of the TiAl alloys developed to date. Over the past 25 or …

Refining the grain size of γ-TiAl alloys to improve their strength and ductility is of academic
interest. Thus, we report a multi-stage heat treatment method consisting of solution …

A β-solidifying TiAl alloy with a refined microstructure and ultra-fine yttrium-rich precipitates
that was consolidated by spark plasma sintering was investigated by scanning and …

Boron is the most commonly used grain refining element in γ-TiAl alloys and the morphology
of the borides has a significant influence on the room temperature plasticity of γ-TiAl alloys …

Abstract (Ti 3 Al+ TiB)/Ti composites were fabricated on Ti6Al4V substrates by laser cladding
(LC) to improve the wear and high temperature oxidation resistance simultaneously. The …

In order to precise the role of the electric current involved in the spark plasma sintering
(SPS) technique on the microscopic mechanisms occurring at the necks between TiAl …

This work deals with the densification of TNM alloys by spark plasma sintering. Pre-alloyed
powders with composition Ti–43.9 Al–4Nb–0.95 Mo–0.1 B (at.%) were sintered between …

In this Communication, it is shown that the production of turbine blades in γ‐TiAl alloys
through Spark Plasma Sintering (SPS) is a viable manufacturing route, by demonstrating …

The effects of ageing at 800° C on the properties of the IRIS alloy (Ti 49.9 Al 48 W 2 B 0.1)
are studied. The initial microstructure of this alloy densified by Spark Plasma Sintering (SPS) …
