Abstract
In this paper, we study the effect of cryogenic treatment on the microstructure and properties of high-strength D6AC steel with a bainite and martensite structure. The transformations occurring in steel during heat treatment above and below 0°C was dilatometrically studied. Cryogenic treatment in liquid nitrogen is shown to lead to almost complete restoration of the sample size, which indicates a decrease in the fraction of retained austenite in the structure. This is confirmed by the results of X-ray diffraction analysis. Cryogenic treatment is established to lead to increasing the strength properties and reducing the ductility of D6AC steel.
低温加工对高强度钢 D6AC 微观结构和性能的影响
摘要 本文研究了低温处理对具有贝氏体和马氏体组织的高强度 D6AC 钢的显微组织和性能的影响。在 0°C 以上和 0°C 以下的热处理过程中，对钢中发生的转变进行了扩张计法研究。在液氮中进行的低温处理几乎完全恢复了试样尺寸，这表明结构中残留奥氏体的比例有所下降。X 射线衍射分析的结果也证实了这一点。低温处理可提高 D6AC 钢的强度性能，降低其延展性。

期刊介绍：
Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
