Refinement of grains and intermetallic phases in the as-solidified alloy structure offers
uniform structural properties, eliminates or minimizes common solidification defects …

Acoustic streaming and its attendant effects in the sump of a direct-chill (DC) casting process
are successfully predicted under ultrasonic treatment for the first time. The proposed …

The formation of fine, non-dendritic equiaxed grains throughout a casting without the
addition of refiners (ie independent of alloy chemistry), is made possible by using ultrasonic …

In this work, we study how ultrasonic cavitation melt treatment (UST) affects the temperature
distribution, sump profile, and resulting microstructure in the direct-chill (DC) casting of an …

Proposed grain refinement mechanisms during ultrasonic solidification have been explained
in terms of refinement between cavitation enhanced nucleation and fragmentation of …

The present work investigated melt flow pattern and temperature distribution in the sump of
aluminum billets produced in a hot-top equipped direct chilling (DC) caster conventionally …

铝合金广泛应用于航空航天, 轨道交通, 汽车轻量化等领域. 半连续直接冷却铸造技术是制备大型
铝合金铸锭的重要方法. 在此制备工艺中热裂是较为严重的铸造缺陷, 该缺陷的控制是制备优质 …

This work focuses on the effects of ultrasonic melt treatment (UST) during direct-chill (DC)
casting on the temperature distribution across the billet, sump profile, and the resulting …

Solidification processes during casting that promote equiaxed, fine and non-dendritic grains
tend to combat the propensity for porosity formation and hot tearing by introducing enhanced …
