The Alnico 8 alloy has been printed using the selective laser melting additive manufacturing approach, resulting in material with magnetic properties in the as-printed state comparable to properties produced by conventional casting or powder metallur

In situ heating experiments explore a correlation between hexagonal close-packed (HCP) domains in sputter-deposited Ni-25Mo-8Cr films and the precipitation of HCP-type structures (Ni3Mo). Dynamic observation of phase evolution in diffraction mode con

Overall kinetics of lamellar overaging reactions in U-5.5Nb and U-7.5Nb were analyzed by Avrami-Arrhenius analyses of volume fractions measured from an extensive temperature-time (T-t) matrix of specimens. The cellular initiation site (grain boundari

The oxidation behavior of nanograined and coarse-grained alloys may differ significantly. This empirical observation has been justified on the basis of accelerated grain boundary diffusion. However, thermal destabilization of nanograined microstructu

Precipitation pathways in many nickel-based superalloys are highly complex and in some cases proceed very slowly. This behavior has hampered their introduction into some novel application spaces ranging from microelectromechanical systems (MEMS) to p
