چکیده
The solidification behavior of pure aluminum in truncated cone shaped mold was studied to unravel the effect of section size on the as-cast structure, cooling curve, and solidification time. For this purpose, phenolic resin mold having the shape of truncated cone was considered and three K-type thermocouples were inserted in different cross sections of the mold and the continuous cooling curves from the pouring temperature were recorded using an accurate data acquisition system. It was revealed that by decreasing the cooling rate, the solidification time increases significantly. Subsequently the Chvorinov Rule was used to correlate the solidification time with section size through the geometrical modulus. These quantitative analyses can shed light on the processing of as-cast aluminum alloys.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
