Metallurgy martensitic steels

Metallurgy was one of the first fields where material scientists worked toward developing new alloys for different applications. During the first years, a large number of studies were carried out on the austenite-martensite-cementite phases achieved during the phase transformations of the iron-carbon alloy, which is the foundation for steel production, later the development of stainless steel, and other important alloys for industry, construction, and other fields was produced.

Purthermore, as mentioned in Section 9.1, FM steels have also been chosen as structural materials for high dose components of other nuclear systems such as fusion reactors. The fusion community has developed new FM steels, called reduced-activation ferritic-martensitic (RAFM) steels, derived from conventional FM steels, with the objective to achieve enhanced radioactive decay resulting in reduced activation following the end-of-life of the components. To this end, radiologicaUy undesirable elements, such as Mo and Nb, were replaced by W and Ta [24]. The physical metallurgy and mechanical... 

Physical metallurgy is a rather wide field of applications of Mossbauer spectroscopy and it is possible to enumerate only the main topics phase analysis, order-disorder alloys, surfaces, alloying, interstitial alloys, steel, ferromagnetic alloys, precipitation, diffusion, oxidation, lattice defects etc. Alloys are well represented by the iron-carbon system, the mechanism of martensite transformation, high-manganese and iron-aluminium alloys, iron-silicon and Fe-Ni-X alloys.
