Investigation made on gasting aluminium alloys AL2, AL9, AK5M2, AK12M2MgH and VAL10. On the bases of theoretical ground of the mechanism grainrefinement aluminium alloys by refractory particle scandium-containing compounds was eleboration the technology of particle reinforeing of casting aluminium alloys. The scandium-containing compounds introduce into the melt alloys in composition of a scandium-containing flux. It was shown that the application of particle reinforeing technology of aluminium alloys (smeldet with of application into composition scrap and waste products ofpersonally productiopn) in found departments of machine building werks bring to increase mechanical characteristic casting by 15 or 30 %/ Simultaneons ly reduce the production casts of the finished castings by 10% at smb's expense economy of best guality raw materials Product Description popup.authors popup.nrat_date 2020-04-02 Close
