摘要：
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Bauteilen aus Magnesium oder Magnesiumlegierung durch Sintern. Damit lassen sich erstmals Bauteile aus Magnesium oder Magnesiumlegierung herstellen, die eine hervorragende Elastizität bei ausreichender Festigkeit herstellen. Solche Materialien sind als biokompatible Knochenimplantatmaterialien verwendbar.Producing components of magnesium or magnesium alloy, comprises: producing green compact of magnesium powder and/or magnesium alloy powder transferring green compact in inner sintering crucible placing inner sintering crucible in outer sintering crucible surrounding inner sintering crucible, which has been placed in outer sintering crucible, with getter material heating outer sintering crucible having in it a inner sintering crucible and getter material to sintering temperature of green compact and allowing outer sintering crucible to cool after green compact has been sintered. Producing components consisting of magnesium or a magnesium alloy by sintering, comprises: producing a green compact consisting of magnesium powder and/or a magnesium alloy powder and, if appropriate, an additional alloying constituent transferring the green compact into an inner sintering crucible placing the inner sintering crucible into an outer sintering crucible surrounding the inner sintering crucible, which has been placed in the outer sintering crucible, with a getter material which is able to bond gases and/or impurities heating the outer sintering crucible, with the inner sintering crucible inserted into it, and the getter material to sintering temperature of the green compact and allowing the outer sintering crucible, with the inner sintering crucible inserted into it, and the getter material to cool after the green compact has been sintered in order to produce the component consisting of magnesium or a magnesium alloy. An independent claim is also included for a component consisting of magnesium or a magnesium al
