摘要
The paper reports the findings in the development of "A" segregation streaks in large ingots which were cast under various solidification conditions: different bottom shapes of ingots and metal pouring using inoculated stream. It is shown that changed conditions bring about a decrease in the "A" segregation zones as well as reduced diameters and shorter lengths of "A" segregation streaks. A different design of the ingot bottom and smaller streaks reduce the chemical heterogeneity of ingots and improve the anisotropy of the forgings fabricated from the ingots.
