Positronium time-of-flight spectroscopy of dissimilar metals
Physical Review B, 1987Positronium velocity distributions using the time-of-flight technique have been determined for positronium emitted from clean, well-annealed, single-crystal samples of Al(111), Cu(100), Ni(100), and Au(100). The positronium energy distribution had a similar shape for all samples and was consistent with the hypothesis that positronium formation leaves ...

Femtosecond fiber laser welding of dissimilar metals
Applied Optics, 2014In this paper, welding of dissimilar metals was demonstrated for the first time, to the best of our knowledge, by using a high-energy high-repetition-rate femtosecond fiber laser. Metallurgical and mechanical properties were investigated and analyzed under various processing parameters (pulse energy, repetition rate, and welding speed).

Ball impact cladding of metals with dissimilar metallic foils
Surface and Coatings Technology, 2009Ball impact cladding is a process in which solid-state welding of a foil and substrate is carried out in a vibration mill. The principle of the process is that a substrate and foil are fixed at the top of a vibration chamber. During the subsequent mechano-activation process, the materials are subjected to high-energy collision with balls.
