    • The present invention ('PISTON RINGS OF CAST NITRIDABLE STEELS AND PROCESS OF PRODUCTION') describes an alloy and the process for the obtainment of cast parts suitable for piston rings of nitridable steels having a relatively high content of N and having low contents of Si. In this invention the fraction of M 7 C 3 eutectic carbides is reduced to fractions of less than 2.0% by weight through the substitution of part of C by N and, in addition thereto, these eutectic carbides are transformed into M 23 C 6 carbides during the stage of heat treatment. This transformation is accompanied by an alteration in the morphology of the carbides, reducing the maximum size thereof and the continuity thereof in the microstructure of the material. This microstructural alteration of the material of the present invention is due to the chemical composition (low contents of Si and relatively high contents of N) and appropriate heat treatments. The rings of cast nitridable steels having low contents of Si and high contents of nitrogen obtained in the present invention have overcome the limitations imposed by the processes and/or materials belonging to the present state of the art, these being: limit of loading whereunto the rings of cast iron may be subjected, dimensional limits of the process of shaping wires of stainless steels, and formation of coarse carbides in the alloys proposed in the document US 20120090462. The following table shows the limits of composition for the material.
    • 本发明(“可活化铁的活塞环和生产方法”)描述了一种合金和获得适合于具有相对高的N含量且具有低Si含量的氮化钢的活塞环的铸造件的方法。 在本发明中,M7C3共晶碳化物的分数通过将C部分C替代为N而减少到小于2.0重量%的分数,此外,在热处理阶段,这些共晶碳化物转化为M23C6碳化物。 这种转变伴随着碳化物形态的改变,减小了其最大尺寸和材料的微结构的连续性。 本发明的材料的微观结构改变是由于化学成分(Si含量低,N含量相对较高)和适当的热处理。 在本发明中获得的Si含量低和氮含量高的铸造氮化钢环已经克服了属于现有技术的工艺和/或材料所施加的限制,这些限制是: 在文献US 20120090462中提出的合金中可能会承受铸铁环,不锈钢成型线的过程的尺寸限制和粗大碳化物的形成。下表显示了该材料的组成的极限。
