Experiments were performed to determine the effects of hydrogen segregation at grain boundaries on intergranular fracture of charged nickel deformed in tension. Two modes of hydrogen segregation are investigated; lattice ...

Two separate experiments were performed in order to understand the roles of bulk diffusion and surface processes in hydrogen transport in and through niobium. Bulk hydrogen and deuterium diffusivities and permeabilities ...

Experimental and theoretical results are presented for segregation of dopants in single-crystal semiconductors grown by molecular beam epitaxy (MBE). Experimental results include Sn doping of GaAs, Si doping of Ga(,x)Al(,x)As ...

The nonequilibrium glassy state of polymers has been examined using Fourier-Transform Infrared (FTIR) spectroscopy. The nonequilibrium nature of polymer glasses induces a physical aging process which results in time dependent ...

Interfacial microstructures in two divorced graphitic eutectics have been investigated using transmission electron microscopy (TEM). Both systems show a coarse minor precipitate, graphite, whose morphology depends strongly ...
