Abstract (en)
[origin: EP0884123A2] Production of a foamable metal body is carried out by compacting a mixture of metal powder and a magnesium hydride-containing gas-evolving blowing agent. Preferably, the blowing agent consists of magnesium hydride, optionally together with other metal hydrides (especially titanium hydride), carbonates, hydrates and/or easily vaporised materials. Also claimed are (i) a compacted semi-finished product obtained by the above process; (ii) use of the above compacted semi-finished product for foaming a closed-cell metal body, preferably in a mould cavity, by the action of elevated or reduced pressure and/or elevated temperature; and (iii) a closed-cell foamed metal body obtained from the above compacted semi-finished product.
