<p>The invention relates to a method for producing exact parts by laser a sintering powder material consisting of a mixture of at least two powder elements. The inventive method is characterized in that the powder mixture is formed by the main constituent iron powder and by other power alloy elements, which exist in elementary, prealloyed or partially prealloyed form, and in that over the course of the laser sintering process, a powder alloy is formed from these powder elements. The following powder alloy elements are added to the iron powder separately or combined in any manner: carbon, silicon, copper, tin, nickel, molybdenum, manganese, chromium, tungsten, vanadium, titanium, phosphorous and boron.</p> |
