Abstract
Casting defects such as gas traps and oxide particles must be removed in the die-casting process in order to obtain good cast products. Experimental research is costly and time-consuming, so computer simulations are typically performed in advance and then compared to experimental results. In this paper, a magnesium alloy die-casting..... More

Abstract
The world is gradually running short of high quality iron resources. This forces ironmaking processes to focus on the use of low quality iron ores. Carbon composite iron oxide briquettes (CCB) are one of the alternative choices. CCB enables the utilization of low quality powdered iron ores and coal, and..... More
