The Effect of the Chemical Composition to the End-Properties of Ceramic Dispersed Strengthened 316L/Y2O3 Composites

In this paper the influence of chemical composition to the end-properties of ceramic dispersed strengthened 316L/Y2O3 composites ceramic has been studied. Two various compositions were studied and compared to reference 316L sintered sample. These two compositions are 316L/0.33 wt% Y2O3 and 316L/1 wt% Y2O3. The high-efficient attrition milling has been used for grain size reduction and oxide distribution in the austenitic matrices. Spark Plasma Sintering (SPS) was used as fast compaction method of the milled powders in order to avoid excessive grain growth. In this work it was found that changing the chemical composition by increase of the Y2O3 addition in the composite matrix improves the milling efficiency, increases the hardness of the 316L and reduces significantly the wear rate.
