关于铁合金中相变的详尽显微组织方面的早期研究之一是由艾伯特·苏佛教授的学生周志宏（哈佛大学博士，１９２８年）完成的。该项研究描述了铁碳合金中魏氏组织和马氏体的形成，所用合金具有宽的碳含量范围，热处理时采用的冷却速率范围也是宽的。还描述了一种独特的汞浴淬火方法。此研究工作从未完全发表过。本文援引该博士论文中的一些原始显微组织照片和部分原文，并试图用我们现今对于铁合金相变的理解来阐明和重新诠释。文中还包括中国引进现代工业和科学的历史背景，以及周志宏对苏佛教授的个人回忆。
One of the earliest studies on the detailed microstructure of phase transitions in ferro-alloys was done by student Dr. Albert Suver, a PhD student at Harvard University (1928). This study describes the formation of Wei’s microstructure and martensite in iron-carbon alloys with a wide range of carbon contents and a wide range of cooling rates for heat treatment. A unique mercury bath quenching method is also described. This research has never been published completely. This paper cites some original photomicrographs and some of the original texts from this PhD dissertation and attempts to clarify and reinterpret us with our current understanding of the phase transitions of ferroalloys. The article also includes the historical background of China’s introduction of modern industry and science, as well as Zhou Zhihong’s personal memories of Professor Su Fo.
