Polymeric aerogels are used in this study to bind foundry sand forming thus a new kind of mould and core material called AeroSand. A core and mould material in general shall be able to withstand all handling stresses in a foundry shop, withstand the thermal and mechanical stresses exerted onto them during casting, but should also easy removable from a casting. Therefore mechanical properties are important...
The bulk Al85La10Ni5 alloy is sintered by spark plasma sintering (SPS) method. The microstructure and mechanical properties of the Al85La10Ni5 samples are investigated. The results show that the bulk Al85La10Ni5 alloy with less than 1.5% porosity has been obtained at 693 K. The hardness of the alloy sintered at 693 K reaches HRB 98 and the wear resistance of the alloy is twice of the conventional...
