Carbon Distribution in Ferritic-Martensitic Fe-Cr-C Alloys

Martensitic Transformation in Microcrystalline Melt-Quenched Fe-Ni Alloys

The features of martensite transformation in Fe (31 32)% Ni melt-quenched alloys are considered. The meltquenching was realized by spinning technique with variable parameters. The influence of the melt-quenching on structural and kinetics transformation parameters is revealed. In particular Ms point is shown to decrease but volume percentage of athermal martensite is found to be invariable with...

Atomistic Study of Surfaces and Interfaces of Fe-Cr and Fe-Cr-Al Alloys

Surface and interface properties of Fe-Cr, Fe-Al, and Fe-Cr-Al are studied using Exact Muffin-Tin Orbitals and Monte Carlo methods and with x-ray photoelectron and Auger electron techniques. Surface composition is investigated as a function of oxidation (heating) time. Hard x ray photoelectron spectroscopy (HAXPES) is used to scan non destructively the compositions below the surface. It is foun...

Cavitation erosion of laser processed Fe-Cr-Mn and Fe-Cr-Co alloys

Purpose: Purpose of this paper is attempt explanation how laser beam processing influence on the cavitation performance of the Fe-Cr-Mn and Fe-Cr-Co alloys. This kind of alloys are frequently used in Polish power plants to routine repairs of damaged blades working under cavitation loading. Design/methodology/approach: Padding welds of investigated alloys were tested for three cases: after laser...

Cavitation erosion behaviour of laser processed Fe-Cr-Mn and Fe-Cr-Co alloys

Purpose: Purpose of this paper is investigation of influence of the surface processing by laser method on the cavitation performance of the Fe-Cr-Mn and Fe-Cr-Co alloys. This kind of alloys are frequently used in Polish power plants to routine repairs of damaged blades working under cavitation loading.
