Kuzmin P.B., Kuzmina M.Y. About production of primary siluminsingots medified with strontium
A raw of production regularities of primary casting alloys ingots AlSi7Mg; AlSi7MgSr; AlSi11Mg; AlSi11MgSrwere studied. The features of melting and casting of the alloys as well as influence of strontium and silicon on shrink defects formation were examined. It was reviled that strontium as modifier not only changes the silicon morphology but also the type of alloy solidification and shrinkage. The particular attention was given to defects on the ingots based on almost eutectic AlSi11MgSr alloy.
Key words: aluminum alloy, strontium, melting, ingots, grain refining, macro- and microstructure, alloying, impurity, mechanical properties, porosity, shrink defects.

Yurkov I.I., Anikin M.V. Enhancement of Service Durability of Dies and Chill Molds for Casting Nonferrous Alloys
Increasing service life of dies and chill molds used for casting nonferrous alloys is topical for existing foundries. This subject is given much attention. At the same time,the process of using casting tooling is very complex and multifaceted, as it requires taking into account many factors, and therefore has no universal solutions. At the same time, the possibility of enhancing service durability of casting tooling should be pointed out. The article focuses on this subject.
