Pulvermetallurgisk fremstillet materiale med forbedret isopropi af de mekaniske egenskaber

摘要

The toughness of the material which is produced by forging or rolling blanks, measured in any direction more particularly the thickness of the cross section, is greater than that of the material in the hot isostatically pressed unformed state. The material whose width is 3.1 times the thickness has a rectangular or flat elliptical cross section and during re-shaping the difference between the deformation in the direction of the width and the deformation in the thickness direction is at most twice the lower deformation value.
