where the specimens are recovered but not recrystallized. This second type of yielding is characterized by a sharp yield drop and long yield elongation. A mechanism of the second type of yielding has not been investigated, but it is clear that the yielding phenomenon is not due to a simple effect of strain aging, because the specimens has recovered so that dislocation arrangements should have c...

| Assuming a multipath propagation scenario, we derive a closed-form subspace-based method for the simultaneous estimation of arrival angles and path delays from measured channel impulse responses, using knowledge of the transmitted pulse shape function and assuming a uniform linear array and uniform sampling. The algorithm uses a 2-D ESPRIT-like shift-invariance technique to separate and estim...

Composite coatings of Co–Ni–Al O were studied by electrolytic codeposition of Co–Ni alloys and Al O from a sulfamate 2 3 2 3 electrolyte containing Al O particles. The influence of plating parameters on the content of the co-deposited Al O particles in 2 3 2 3 Co–Ni alloys was investigated. The maximum value of co-deposited Al O can be achieved at a particle content of 80 g l in y1 2 3 bath, a ...
