摘要

参照平衡相图，压实和球状石墨硅铸铁通常具有轻微的高共晶成分。以往的研究表明，这些熔体的热分析常常表现出误导性特征，从而妨碍正确的工艺控制。考虑到碳当量以及球化和接种水平，本研究旨在提供新的结果。总体而言，以往研究中推断出的轻微和高度过共晶熔体的特征得到了证实，同时还获得了有关球化和接种水平影响的更多信息。

Effect of Spheroidization and Inoculation on the Early Solidification Steps of Hypereutectic Cast Irons

Compacted and spheroidal graphite silicon cast irons generally have slightly hypereutectic compositions when referred to the equilibrium phase diagram. Previous studies have shown that the thermal analysis of these melts often exhibits misleading characteristics that could prevent proper process control. It was the aim of the present work to provide new results, taking into account the carbon equivalent as well as spheroidization and inoculation levels. Overall, the features of slightly and highly hypereutectic melts deduced from previous studies were confirmed, while additional information was obtained concerning the effect of spheroidization and inoculation levels.

期刊介绍： The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
