Materials obtained by mechanical working of metal powder compacts and composites

摘要

Results of testing methodes for obtaining materials with special properties from aluminium powder and composites on its matrix reinforced by either SiC particles or Al_2O_3 fibers and burnish mg of sintered steel have been presented. Such material can be used to produce structural elements. The influence of extrusion conditions on structure and properties of obtained materials and col burnishing parameters on properties of sintered steel has been discussed.
