The Grain Control of 65:35 Brass Sheets : The Effect of Casting Methods on Grain Size

摘要

As for the grain cont rol of brass sheets, there have already been various researches, such as those by Bassett & Davis and Burghoff & Bohlen and so forth. The prsent authors have noticeed the interesting fact that, according to the difference of the chill mould, bran mould and continuous mould, there appears a corresponding difference in the casting structure, especially in the β kept in unbalanced state resulting from segregation and in the mixing of oxides. This report is to show how the difference mentioned abve gives the influence on 65:35 brass in recrystallization and grain control.
