Diffusional broadening
WebRadiation-enhanced diffusional broadening of implanted Ni ions (at 400–550 °C) in Fe and Fe-Cr was up to 250 nm toward the surface, which leads to a much broader near-peak-damage region where ... WebFrom the diffusional broadening the diffusion coefficient can be determined. Furthermore, the jump vector can be obtained, which enables conclusions with respect to the diffusion mechanism. As the line broadening must be comparable to or exceed the natural linewidth in QMS and the energy resolution in QNS, ...
