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

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. [...]
