In this research the effects of; increasing the amount of nickel and adding aluminum to create and prolong sulfidation resistance of Fe-Ni-Cr alloys have been investigated. Sulfidation tests were carried out at 1100°C in S/O bearing atmosphere. Prior to the tests, the specimens were annealed in argon at 1250°C for 8 hrs. Weight changes were measured and corroded deposits were analyzed byscannin...

a r t i c l e i n f o It is well known that strong concurrent precipitation, mainly located along grain/subgrain boundaries, results in a coarse and elongated grain structure, and unusual sharp P {011} b566N and/or M {113} b110N texture components during annealing of supersaturated AA3xxx-series alloys. In this study, a supersaturated as-cast Al–Mn– Fe–Si alloy was annealed at three temperature...

The article contains computational data of many-body interactions in Al-Cu alloys, obtained using PAW-VASP calculations. Pairwise, three-site, and four-site interactions are presented. Mentioned data are relevant to the research article "Many-body mechanism of Guinier-Preston zones stabilization in Al-Cu alloys" (Gorbatov et al., 2017) [1].

The present paper gives a review of results of recent studies investigating the fundamentals of the martensitic and related phase tr-ansformations in Ni-A]. For the former case, the emphasis will be on the microstructure of martensite plates. The latter include the metastable Ni2A1 o-like and stable Ni5A13 bainitic phases. These phases will be discussed in view of their atomic structure, nuclea...

It is well known that plastic deformation induced by conventional forming methods such as rolling, drawing or extrusion can significantly increase the strength of metals However, this increase is usually accompanied by a loss of ductility. For example, Fig. 1 shows that with increasing plastic deformation, the yield strength of Cu and Al monotonically increases while their elongation to failure...
