The new technology for porous material producing
The new technology of producing unsinkable material from the aluminum alloy was patented at the Peter the Great St. Petersburg Polytechnic University (SPbPU). The effect of porosity is produced by addition of foaming gas into liquid metal during re-melting of the aluminum material. The porous materials can be used for increase of structures stiffness and Read more about The new technology for porous material producing[…]
