Abstract(s) :

(Anglais) In this research, the behavior of a parent glass powder of Sr2TiSi2O8 under selective laser remelting / devitrification is investigated. Powder compacts have been treated in order to characterize the response of the powder according to the laser scan conditions (power, spot speed and vectorization step of the scan lines). The structure of the surface after selective laser treatment by a Nd-YVO4 (20W / 40 µm spot size / cw mode) have been evaluated by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectrometry.
