日本东北国家工业研究所的科研人员研制出一种细石墨颗粒弥散技术 ,用于含微量钛和锆的中碳钢在 5 0 0～ 70 0℃的热处理。从而使钢的冷加工性和力学性能得到实质性的提高。这项新技术能够保证 1～ 2ｈ完成石墨化 ,只相当于过去所需时间的十分之一。 3～ 5 μｍ尺寸的细石墨呈?
Researchers at the National Institute of Industrial Science of Japan’s Tohoku Institute of Technology developed a fine graphite particle dispersion technology for the heat treatment of medium carbon steels with trace amounts of titanium and zirconium at temperatures ranging from 500 to 700 ° C. So that the steel cold workability and mechanical properties have been substantially improved. This new technology guarantees 1 to 2 hours to complete graphitization, which is equivalent to only one tenth of the time required in the past. 3 ~ 5 μm size of fine graphite was?
