Abstract

Gegenstand der Erfindung ist ein Verfahren zur Herstellung schäumbarer Metallkörper, das so erhältliche kompaktierte Halbzeug, die Verwendung des Halbzeugs zum Schäumen eines geschlossenzelligen Metallkörpers sowie die so erhaltenen geschlossenzelligen schaumförmigen Metallkörper.
Die Gemische der schäumbaren Metallkörper werden aus wenigstens einem Metallpulver und einem gasabspaltenden Treibmittel hergestellt und zu einem Halbzeug kompaktiert, das dadurch gekennzeichnet ist, daß man ein Magnesiumhydrid enthaltendes gasabspaltendes Treibmittel einsetzt.
