✦ Synopsis

Ti and Cu samples were exposed in ambient atmosphere and vacuum (0.66mPa) to single pulse (0.2-2.6 J) ruby laser radiation in the Q-switch (30 ns) and free generation regimes f 150&

Acoustic recordings during irradiation were carried out and the resulting damage was analyzed by light and scanning electron microscopy. In contrast to vacuum conditions, it is observed in the air that the damaged area was much larger due to plasma effects and also that cracking of the Ti samples and oxidation of the Cu samples occurred.

The presence or the absence of the Portevin-Le Chatelier effects in Cu-P, Cu-Ti and Cu-Si alloys were investigated as functions of solute content, temperature and heat treatment. The serrated flows were observed in all the systems but in the Si bearing alloys it appeared at higher solute content and
