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 …

Intermetallic γ-TiAl based alloys are innovative lightweight structural high-temperature
materials used in aerospace and automotive applications due to already established …

Spark Plasma Sintering (SPS) is used to process TNB alloys. Pre-alloyed powders (Ti–46Al–
9Nb) were sintered between 975° C and 1300° C under 100MPa. The microstructures of the …

In the present study, the spark plasma sintering technique is used to densify pre-alloyed TiAl
powders. Ti49Al47Cr2Nb2 and Ti51Al44Cr2Nb2B1 powders are sintered at temperatures …

A high Nb containing TiAl alloy from pre-alloyed powder of Ti–45Al–8.5 Nb–0.2 B–0.2 W–
0.1 Y was processed by spark plasma sintering (SPS). The effects of sintering temperature …

This work presents a study of the Spark Plasma Sintering of a boron and tungsten containing
alloy (Ti 49, 92 Al 48 W 2 B 0, 08, called IRIS) as a function of the sintering temperature …

Research and development of alloys based on the intermetallic γ-TiAl phase is experiencing
a renewed interest since powder metallurgical approaches provide new near-net-shape …

This work aims at identifying, by coupled scanning and transmission electron microscopy
(SEM and TEM) observations, the densification mechanisms occurring when an atomized Ti …

Metal injection molding (MIM) process was applied to fabricate parts of high Nb containing
TiAl alloys with a nominal composition of Ti–45Al–8.5 Nb–0.2 W–0.2 B–0.02 Y (at.%), and …

Abstract Gas-atomized Ti–45Al–7Nb–0.3 W alloy powders were consolidated by the spark
plasma sintering (SPS) process. The densification course and the microstructural evolution …
