알루미늄의 결정입자 미세화에 미치는 AlTi5B1 첨가의 영향
The Effects of AlTi5B1 Additions on the Grain Refinement of Aluminium
초록
Titanium-Boron-Aluminium master alloys are used extensively to grain-refine a wide range of aluminium alloys. This experiment was performed by various amounts of AlTi5B1 addition to the technical aluminium alloys, and also by changing cast temperature and hold time of the melts. The macrostructures were shown that with increasing the addition of AlTi5B1 to the melts, the grain became finer. In the case of cast temperature high enough over
