The research concerns the optimisation of sintering zirconium by spark plasma sintering (SPS) and modification of microstructures by introducing the manganese component. The problems of preparing mixtures for sintering were investigated. An additive of 2.5 wt% and 5 wt% manganese micropowders and 1 wt% and 2.5 wt% manganese nanopowders were utilized. An increase in the oxygen content in sintered mixtures made of zirconium and manganese along with an increase in their milling time in water was found. 100 rpm was determined as a safe mixing speed. The introduction of manganese nanopowders into zirconium did not significantly improved the homogeneity of the material. Manganese in larger quantities accumulates at the grain boundaries. The material is very difficult to machining, which is indicated by difficulties in sample preparation.

添加锰对SPS锆的制备和显微组织测试

该研究涉及通过火花等离子体烧结(SPS)来优化锆的烧结以及通过引入锰成分对显微组织进行改性。研究了制备用于烧结的混合物的问题。使用了2.5重量%和5重量%的锰微粉和1重量%和2.5重量%的锰纳米粉的添加剂。发现锆和锰制成的烧结混合物中的氧含量增加,并且在水中的研磨时间增加。确定100 rpm为安全混合速度。将锰纳米粉体引入锆并没有显着改善材料的均质性。大量的锰积累在晶界处。这种材料很难加工,这在样品制备中很困难。
