  journal={Acta Materialia},
Abstract The effects of ageing at 800 °C on the properties of the IRIS alloy (Ti49.9Al48W2B0.1) are studied. The initial microstructure of this alloy densified by Spark Plasma Sintering (SPS) is mainly composed of lamellar colonies which are surrounded by γ grains. The evolutions of the alloy strength and creep resistance resulting from this ageing treatment are measured by the related mechanical tests. The microstructural changes are investigated by scanning and transmission electron…
