Information × Registration Number 0206U002849, 0103U003206 , R & D reports Title Working up of efficiently technology of modification of foundry alloys and way of impovement mechanical and pertomance attributies. popup.stage_title Head Kutsova V., Registration Date 24-02-2006 Organization National Metallurgical Academy of Ukraine popup.description2 The scientific rules have scientific - practical value from the point of view the addition and development of scientific knowledge in the materials science, microstructure analysis area, and also from the point of view the methodical approaches. The practical value scientific results is, that the major factors are revealed by theoretical generalizations of complex research results on the basis of the structure formation established laws and received optimum modes of thermal processing. These major factors define a necessary complex of properties modified hypoeutectic and hypereutectic silumine. The technology of modifying Al-Si, Sr, Y, La alloys is developed, this technology prevent from formation of harmful fluorine and chlorine gases, and pollution by them of a shop atmosphere and environment, improves a equipment condition, reduces quantity of harmful impurity in alloys. The Al-Si-Sr, Al-Si-Y, Al-Si-La etc. threefold alloying composition will ensure the reduction of Sr, Y, La expenses on modifying,rather than at use the Al-Sr, Al-Y, Al-La double alloying composition, at the expense of their optimum composition and structure. The job results will be used on the "Мотор Січ" LTD at modifying hypoeutectic and hypereutectic silumine. Product Description popup.authors popup.nrat_date 2020-04-02 Close
