Upon aging at 300-450 °C, nanosize, coherent Al 3 (Sc 1Àx Ti x ) precipitates are formed in pure aluminum micro-alloyed with 0.06 at.% Sc and 0.06 at.% Ti. The outstanding coarsening resistance of these precipitates at these elevated temperatures (61-77% of the melting temperature of aluminum) is ex

The phase transformation in NiTi shape memory alloys is very sensitive to aging and thermomechanical treatment (cold work and annealing). In this research, a Ni-rich alloy has been cold-rolled and then subjected to various annealing treatments and also aging treatments at different temperatures and
Compression tests were performed on the well-annealed coarse grained (CG) and the near dislocation-free ultrafine grained (UFG) 5083 Al alloys at 298 K and 77 K. The mechanical behavior of the CG alloy was dominated by the stage III hardening at 298 K and the stage II hardening at 77 K. The microstr
Understanding the stability of the three-phase Mo\_ss + Mo 3 Si + Mo 5 SiB 2 region is important for alloy design of Mo-Si-B-based refractory metal intermetallic composites. In this work, thermodynamic modeling is coupled with guided experiments to study phase stability in this three-phase region of
