| সংক্ষিপ্ত: | Title screen The effect of TiO2, ZrO2 and Na3AlF6 ultrafine powders on the fine structure and the phase composition of Fe–14Mn–1.2C steel was investigated. The introduction of the ultrafine powders into the melt influenced the grain size, the quantity, and the character of distribution of nonmetallic inclusions in the railroad frogs. The microstructure of castings was improved significantly because of the refinement of the grain structure and an increase of the grain-boundary area. After the modifying mixture was introduced into the melt, either the microtwins of one or two intersecting systems or the precipitations of ?-martensite of different types, or simultaneously the microtwins and wafers of ?-martensite, were present in each grain Текстовый файл AM_Agreement |
