摘要
Process for the powder metallurgical production of wide material plane ledeburitic steel with a rectangular cross section or into a flat ellipse, which exhibits improved mechanical properties, especially a starting material for the manufacture of cutting tools, isotropy punching and deformation, in which a powder is introduced, nitrogen atomized, an alloy in a capsule, compacted and the same is closed, if necessary, after evacuating and then proceed to heating and isostatic pressing ( HIP) the capsule, and the blank thus obtained by hot isostatic pressing is subjected to a process of deformation by forging and / or rolling, characterized in that a blank is made, the cross section has a rectangular shape or flat ellipse and is subjected to a deformation process so that the difference between the deformation in the widthwise direction and deformation in thickness direction of the cross section of flat material and width corresponds at most twice, preferably 1 to 5 times, the lower degree of deformation.
