Abstract

To sinter a light metal alloy, the alloy powder is pressed into a green compact at 90% of its theoretical density. The green compact is sintered at a temperature of 80-95% of the limiting crystallization temperature of the light metal alloy, as the press is removed. The pre-sintered material is given a two-dimensional cold pressing by 10% of its height with a longitudinal distortion of the granules. The material is sintered again at a higher temperature of 90-99% of the limiting crystallizing temperature, with a final calibration and further compression by 1-2% of its height. The metallurgical powder can also incorporate hard materials e.g. SiC, boron carbide, boron nitride, tungsten carbide, and the like.
