Abstract: The Ni–Co–Cr–W–Mo system is critical for the design of nickel-based superalloys. This system stabilizes different topologically close-packed (TCP) phases in many commercially superalloys with high W and Mo contents. Scanning electron microscopy (SEM), transmission electron… read more here.

DOI: 10.1016/j.actamat.2017.12.036
Abstract: Abstract The structural and compositional evolution of precipitates in Al-Mg-Si-Cu alloys were systematically investigated by atomic resolution high-angle annular dark-field scanning transmission electron microscopy and atom probe tomography. In under-aged alloys, most of precipitates have… read more here.

DOI: 10.2320/matertrans.m2016376
Abstract: The morphological evolution of γ′ precipitates and lattice misfit with isothermal aging were closely investigated in wrought Ni-based superalloy Inconel X-750. The γ′ morphology dramatically changes in terms of shape, distribution, coalescence and coherency at… read more here.
