摘要

The search for new applications of austenitic steel obliges us to develop new essay techniques which accept the addition of new nanoalloys and allow comparison with standard steels. The new essay techniques must facilitate the study of alterations, segregations and carbides in experimental nanoalloys. New applications will require new micro and macro structural characteristics; however, as the basic austenitic steel structure cannot be radically changed, obtaining improved mechanical properties is the challenge. Future uses of austenitic steel, due to its critical nature in diverse areas such as the aerospace industry and the electromagnetic sector, will require stringent controls. In order to meet these demands, new essay techniques are required. The successful development of new alloys depends on finding the correct element proportions and grain size of the nanoalloys to be added. Through the precise management of the basic steel and nano element mix, beneficial segregations, in both mechanical and Theological terms, can be produced for current and new applications. Thanks to its low cost and probable future use in a wide range of applications, our trials were conducted with manganese steel which was found to be a representative reference type for austenitic steel in general. Using X-ray diffractometry and cyclical fatigue, we have been able to demonstrate that each nano element can be assigned a specific residual tension. Based on this we have produced a table of mechanical properties by nano type which shows the effect of nano addition on the residual tension of the cast steel produced, and, consequently, on the mechanical properties of the experimental alloys. This allows the identification of the most appropriate alloy for both highly specific future and conventional applications of austenitic steels.
