Analysis of variation of compaction on the formation of micro structure before sintering process

This study aims to find the effect of compaction variations on the shape of the material with SEM in the form of micro-structures. The results of this compaction variation will determine how efficient the power is needed in the formation of a sample, ODS materials are made from various mixtures of powder materials. The powder materials commonly used are Fe and Cr materials and then mixed with other materials, the powder material that has been milled is then compacted with the specified load variation, this is done so that the material is solid before sintering. The variation of compaction carried out in this study with loads of 10 Tons, 20 Tons, 40 Tons and 60 Tons was observed how much influence on the grain size of the material, from the results of metallographic and SEM tests showed at a pressure of 10 Tons the grains were still in the form of medium spheres for 20, 40, 60 Tons of material are seen to bind to each other, for 40 and 60 Tons are not too much change compared to 20 Tons.
