Contribution of SAXS to microstructural investigation of newly developed Mg-Rare Earth alloys for structural applications.

Résumé

New Mg-Y-Gd-Mn alloys, strengthened by a dense fine scale precipitation, have been recently designed for structural applications up to 523 K. The qualitative small-angle X-ray scattering study presented here enlightens the mechanical properties at high temperature of these alloys. Small Guinier-Preston zones have been evidenced in alloys maintained at room temperature after quenching. The metastable phases, studied in parallel using high-resolution transmission electron microscopy and responsible for the good mechanical properties, are difficult to quantify completely owing to their complex microstructure of interconnected globular and faceted precipitates.
