Аннотация: A study is made of a standard pickup preventing coating made from white synthetic aluminium oxide powder and polyvinylbutyral varnish and used for moulds and cores. With 1.5-1.6% of ultradispersed powder in place of white synthetic aluminum oxide, a new coating has been developed having a sedimentation stability of 89 against 70 for the standard coating. Casting surfaces of steel 35L show the roughness of the new coating of 185-190 be absent pickup throughout the casted sample. Members of steels 110G13L and 45L were also put through tests.

   Перевод заглавия: Влияние нагрева алюминиевой прутковой лигатуры на величину частиц алюминида титана
Аннотация: The metal products of machine-building profile manufactured of billets passed through the cycle of melting-crystallization and having microcrystalline structure, demonstrate higher physical-mechanical properties and exploitation characteristics in comparison with the metal products of macro crystalline structure. During the process of melting the refining structure additives are introduced into liquid metal using master alloys for the aim of the structure refinement. In particular, the similar master alloy is the rod aluminum-titanium master alloy containing titanium aluminide particles which are the crystallization centers. It is determined, that the rod heating in the process of its introducing into the liquid metal leads to enlargement of the titanium aluminide particles, that decreases the efficiency of structure refinement. Therefore, in every particular case, it is necessary to optimize the velocity of rod introducing into liquid metal.
