The author studies properties of the Bordoni peak in 99,999 % gold. The following features are considered : influence of type and rate of coldwork on relaxation strength. After traction coldwork, the height of the Bordoni peak is roughly proportional to th ...
The irradiation of metals by energetic particles causes significant degradation of the mechanical properties(1,2), most notably an increased yield stress and decreased ductility, often accompanied by plastic flow localization. Such effects limit the lifeti ...
Submonolayer films of AE on Pt(111) exhibit parallel partial dislocations separated by narrow hcp domains and much wider fcc domains, the large difference in width being atypical of strained metal overlayers on close-packed substrates. Using a two-dimensio ...
The dislocation structures resulting from compression tests on Ni-3 (Al, I-If) single crystals are studied as a function of the deformation temperature between 77 and 900 K. Mechanical parameters are also reported, such as the 0.2% offset stress, the work- ...
In situ cathodoluminescence experiments have been performed to follow the time dependence of the UV luminescence in epitaxial lateral overgrowth GaN specimens. The decrease of the observed intensity and red-shift of the UV peak are interpreted in terms of ...
The introduction of new packages as well as the ongoing miniaturization in SMT make the evaluation of the reliability of solder joints a permanent task. Passive thermal cycling is an important test to evaluate the lifetime of solder joints. However, tin-le ...
