Steel 67SiCr5 is a alloyed carbon steel usually used for production of springs. It is used for load bearing springs, ring-shape springs, spiral springs, anti vibration springs etc. Springs steels are usually distribute in annealed or hardened and tempered state. Heat treating could be performed before or after springs forming. In this article, the ...

The results of two light optical tomographies (LOT) of two-phase steels are presented and compared in this paper. Two-phase steels show a microstructure consisting of a carbon-rich second phase and a ferritic matrix. In this work, microstructures are compared with a martensitic and a bainitic second phase. Tomographies are very important for materi...
