Abstract
Sposób charakteryzuje się tym, że w procesie spieniania kąpieli metalowej w temperaturze 430 - 1200°C, korzystnie 700°C, dodaje się do stopionego metalu cząstki stałe o wymiarach 1-500 µm, a następnie ciekła mieszanka metali z cząstkami stałymi przedmuchiwana jest gazem lub gazami obojętnymi i/ lub aktywnymi w ilości 100 - 800% objętości metalu, przy czym łączna ilość cząstek stałych dodanych i wytworzonych podczas przedmuchiwania osiąga wartości bliskie wartości krytycznej, stanowiącej stosunek gęstości pozornej tych cząstek do ich gęstości rzeczywistej. Ujawniono także zastosowanie do wytwarzania elementów konstrukcyjnych ze spienionych metali, korzystnie na bazie aluminium lub magnezu i ich stopów, zawierających zwykłe zanieczyszczenia, sposobu, w którym w procesie spieniania wprowadzane są cząstki stałe o wymiarach 1 - 500 µm, przy czym łączna ilość cząstek stałych dodanych i wytworzonych podczas przedmuchiwania zapewnia osiągnięcie wartości bliskiej wartości krytycznej, stanowiącej stosunek gęstości pozornej tych cząstek do ich gęstości rzeczywistej, natomiast objętość gazów wykorzystywanych przy spienianiu stanowi 100 - 800% objętości stopionego metalu.The method is characterized in that in the process of foaming the metal bath at a temperature of 430 - 1200°C, preferably 700°C, solid particles of dimensions 1-500 µm are added to the molten metal, and then the liquid mixture of metals with solid particles is blown with a gas or gases of inert and/or active substances in an amount of 100 - 800% of the volume of the metal, wherein the total amount of solid particles added and generated during blowing reaches values close to the critical value, which is the ratio of the apparent density of these particles to their true density. The invention also relates to the use of a method for manufacturing structural elements made of foamed metals, preferably based on aluminium or magnesium and their alloys, containing common impurities, in which solid particles of dimensions 1 - 500 µm are introduced during the foaming process, wherein the total amount of solid particles added and generated during blowing ensures that a value close to the critical value is achieved, being the ratio of the apparent density of these particles to their true density, while the volume of gases used during foaming is 100 - 800% of the volume of the molten metal.
