Title: (EN) method of making high strength bainite article, and article made thereby
(ZH) 制造高强度含铁制品的方法,以及由此制造的制品
Abstract: front page image
(EN) A metallurgy phase is formed in a body of a ferrous alloy by heating the workpiece to a temperature above an austenizing temperature of the alloy and thereafter contacting the workpiece with a quenching medium. Heat is input to the workpiece during at least a portion of the time it is in contact with the quenching medium. The quenching medium and/or the source of heat are regulated so that they work in combination to maintain the workpiece below a holding temperature but above the temperature at which the martensite phase forms in the alloy. After maintaining the alloy at the holding temperature for a predetermined period of time, it is cooled to ambient. In specific implementation scheme, the system works so that a bainite phase is formed in the alloy. Also disclosed are systems for implementing the method.
(ZH)

通过将工件加热至高于合金奥氏体化温度的温度,然后使该工件与淬火介质接触来在含铁合金体中形成预选的冶金相。在工件与淬火介质接触的至少一部分时间期间向工件输入热量。调节淬火介质和/或热源,使它们组合工作将工件维持在保持温度下,该温度高于在合金中形成马氏体相的温度。将合金维持在保持温度下持续预定的时段后,将其冷却至环境温度。在特定的实施方案中,该系统工作以便在合金中形成贝氏体相。本发明还公开了实施所述方法的系统。
