Four Ni-base superalloy diffusion couples with multiphase regions were studied. The diffusion couples contained single-phase (gamma ), two phase( gamma +MC carbide) and three-phase ( gamma + gamma prime+MC carbide) ...

Phase equilibria at 900 °C in the Co-rich Co-Al-W ternary system are investigated through isothermal annealing of six alloy compositions for times up to 8000 h. The volume fraction of the L12-γ′ phase co-existing with ...

The net added fraction of thermally-generated atomic sites, ΔNN, has been measured, during equilibrium heating to near the melting point, in a coarse-grained copper bar of 99.999% purity. The linear thermal expansion, ΔLL, ...

Formatted categorical and numerical variables for multivariate analysis

Binary interdiffusion data as functions of composition in the Mg-Al system are essential in modeling kinetics of phase transformations in multicomponent Mg and Al alloys. Interdiffusion and phase growth kinetics were studied ...

The annealing kinetics of voids in 99.9999 wt% pure aluminum were studied over the temperature range 85 to 209 °C in thin specimens by transmission electron microscopy. The isothermal shrinkage of individual voids was ...

It has been observed that the metals which exhibit anomalous diffusion behaviour are all allotropic in nature. A hypothesis to rationalise this interrationship between the diffusion behaviour and the phase transformation ...

Bulk Self-Diffusion was measure in alpha-Titanium single crystals between 776 and 1132 K using the radiotracer Ti44 and ion beam sputtering for profile sectioning.

Self diffusion of Cr-51 in pure chromium, Cr +20 wt% Ni, Cr +44wt% Ni, and Cr +65%wt Ni has been measured over the temperature ranges of 1000 to 1900, 1000 to 1525, and 900 to 1350 degrees C, respectively.
