Q&P钢的工艺概念已提出了有些年了,它作为一种热处理工艺,生产的组织具有马氏体和富C的亚稳残余奥氏体.工艺包括:控制淬火形成部分的马氏体,然后热处理以使C从过饱和的马氏体中转移到残余奥氏体中.潜在的应用包括具有好的成型性和抗断裂的高强度钢.应用该工艺可生产薄板和厚板,以及用从长锻材生产热处理元件,甚至于铸铁.自2003年一直在实验室研究,早期的工作结果已有发表.近期的研究主要集中于机理方面的细节.国际范围的独立团队在此研究领域也有很多进展.

The quenching and partitioning or Q & P process concept has been developed over the past few years, as a heat-treatment to produce martensitic microstructures with carbon-enriched metastable retained austenite. The process involves partial martensite formation by controlled quenching, followed by a thermal treatment to allow carbon transport from the (supersaturated) martensite into the remaining austenite. Potential applications involve high strength where retained austenite may be beneficial for formability, fracture resistance, etc. The process may be applicable to production of steel sheet and plate products, as well as heat treated components produced from long product forgings, and even cast-iron. The concept has been studied in the authors' laboratories since about 2003 and a series of publications is available documenting much of the early work. More recent studies have focused on understanding mechanistic details, and other independent research groups are now also making advancements in this field.
