Abstract (en)
[origin: DE10039143C1] Production of precise components comprises laser sintering a powdered material consisting of iron powder and further powder alloying elements which produce a powder alloy during the course of the sintering process; and homogenizing, annealing, heat treating, degrading inner faults and/or improving the surface quality. Preferred Features: The powder elements contain (in wt.%): 0.01-2 carbon, up to 1 silicon, up to 10 copper, up to 2 tin, up to 10 nickel, up to 6 molybdenum, up to 2 or 10-13 manganese, up to 5 or 12-18 chromium, up to 2 cobalt, up to 5 tungsten, up to 1 vanadium, up to 0.5 titanium, up to 1 phosphorus, and up to 1 boron. The powder mixture consists of particles with a grain size of 50 to a maximum of 100 mu m.
