Occurrence of a casting defect in a cast-metal object is suppressed, and a crystal structure of the cast-metal object is made fine. When a cast-metal object (8) is to be produced by using a casting mold (10), a metal material generating a free crystal (6) during solidification is melted first. Subsequently, a molten metal (1) including a melted metal material is poured into the casting mold (10). While the free crystal (6) in the molten metal (1) is deposited on a surface (11) of the casting mold (10), the molten metal (1) is solidified in the casting mold (10). Through the above steps, the molten metal (1) is solidified in the casting mold (10), and the cast-metal object (8) is produced. |

The invention relates to metallurgy. The inventive method involves casting low-heated molten metals or alloys into the lined centrifuge crystalliser in a specified order and volumes and in the shortest time in such a way that a gradient smelt is formed along a casting-form radius. The thermodynamic characteristics of the crystalliser together with the superheat value of casted melts, when the greatest volume uniform cooling rate of the gradient melt is equal to or less than 0.5 DEG C/sec, provide the life time thereof which is sufficient for forming the gradient melt, carrying out diffusion processes therein and for organising a crystallisation front extending from the external ring-shaped part of the casting-form towards the center thereof, prior to the generation of natural crystallisation processes. |

169 | METHOD FOR MODIFYING THE GRAIN SIZE OF CAST PRODUCTS OBTAINED FROM COMMERCIAL MELTS | EP06849279.2 | 2006-12-19 | EP2060341A2 | 2009-05-20 | SKALDIN, Nikolaj Nikolaevich; TKACHEV, Sergej Semenovich |
The invention relates to casting. The inventive method for modifying the grain size of cast products consists in carrying out an uniform volume cooling with a rate of 2-10 DEG C/sec in artificial gravitation fields by gradually increasing a gravitational coefficient up to 1000 and in uniformly and sufficiently slowly cooling a melt in the field of force of a centrifuge, thereby in modifying the grain size of a crystalline phase in an anomalous manner along with the gravitation coefficient growth from 10 to 1000. According to said method, at the beginning, the grain size decreases in conformity with the prior art and, afterwards, increases, with a gravitational coefficient specific for each type of melt, in such a way that monostructures are obtained.; The further increase of the gravitational coefficient results in the sharp fall of the grain size and, starting from a certain g-force value, the grain size again slowly increases. |

This method enables us to produce reinforced titanium composite parts with a low manufacturing cost and in which it is possible to control the percentage of reinforcement achieved on the basis of obtaining a titanium composite reinforcement material, formed preferably of titanium borides and/or carbides, by means of SHS techniques, and which is melted together with a consumable ingot of titanium or non-reinforced titanium alloy. The parts produced have a proportion of titanium boride and/or carbide which may range from 0% to 70% by weight. |
