Abstract

The impact properties of an L-PBF 18Ni-300 maraging steel were investigated after different heat and duplex (nitriding and PVD coating) surface treatments. Impact energy is almost isotropic. Contrary to expectations, impact energy is not decreased by surface treatments, since the effect of surface embrittlement of nitriding is compensated by the increase in the austenite content. An important role is played by the geometry of the notch where the surface hardening is lower than in the flat surface of the Charpy specimens.

双相表面处理对激光粉末床熔融法生产的马氏体时效钢冲击性能的影响

研究了一种 L-PBF 18Ni-300 马氏体时效钢在经过不同的热处理和双相（氮化和 PVD 涂层）表面处理后的冲击性能。冲击能几乎是各向同性的。与预期相反，冲击能并没有因表面处理而降低，因为氮化的表面脆性效应被奥氏体含量的增加所补偿。缺口的几何形状起了重要作用，因为缺口的表面硬化程度低于夏比试样的平面。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
