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.
Microstructures of sintered alloys are analyzed by scanning and transmission electron
microscopies. Investigations mainly focus on a fine near-lamellar microstructure. Attention is
paid to both characteristic dimensions of this microstructure and orientation relationships
between various phases. The fine near-lamellar microstructure is formed by lamellar grains …
