Abstract
(EN)
Provided is a multiple property biodegradable metal alloy which comprises: 0.05 to 0.15 wt% of calcium; a metal element X, which has an HCP structure and is in a solid solution in the following magnesium at such a composition range as not to form a separate precipitate phase; and the balance of magnesium.
(FR)
L'invention concerne un alliage métallique biodégradable à propriétés multiples comprenant : 0,05 à 0,15 % en poids de calcium ; un élément métallique X, qui a une structure HCP et est dans une solution solide dans le magnésium suivant à une telle plage de composition pour ne pas former une phase de précipité séparée ; et le reste de magnésium.
