The high-efficient technology of steels modifying by complex master alloys

Bykovskykh S., Jeronko S., Shevchenko A., Bogatskij V.

Krzepnięcie Metali i Stopów

2000

R. 2, nr 43

83--87

As practice shown the modifying of steel is one of most efficient way of steel service characteristic improving as modifying can be able to provide the set totality of necessary properties and structure of metal [1-3] . The change of high-alloyed cast steels on more cheap structural modifying steels is actual because lasts have the more efficient technology of receiving and processing and provide higher level of special service properties. Efficiency of practicable measures for improving a processing steel quality in many depends of chemical compound of used master alloy, ways of input its in liquid melt and conditions of interaction of added materials particle with steel components.

The effect of microalloying on formation of microstructure parameters and thermal concentration state of solidifying melt

Bykovskykh S., Tischenko V., Bykovskykh P.

The problem of improving reliability and casting of fast wearing machine parts, which were manufactured from steel cast, has been required of creation and using practice of various materials. One of most rational ways to cast quality increasing is the using of middle-carbon microalloyed in return for expensive high alloyed steels. For this, the microalloyed steels must possess good casting properties and enough high density of metal and surface quality of cast. [...]
