X-ray diffraction peak profile analysis of maraged Fe-Ni-Mn steels
X-ray diffraction peak profile analysis was used to identify changes in the lattice distortions during isothermal aging of Fe-10Ni-7Mn (wt. %) maraging steel. Integral peak breadths were analyzed using classical Williamson-Hall equation taking the elastic anisotropy into account. It was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the s...

Effect of Density on the Microstructure and Mechanical Behavior of Powder Metallurgy Fe-mo-ni Steels
The microstructure and mechanical properties of Fe-0.85Mo-Ni powder metallurgy (P/M) steels were investigated as a function of sintered density. A quantitative analysis of microstructure was correlated with tensile and fatigue behavior to understand the influence of pore size, shape, and distribution on mechanical behavior. Tensile strength, Young’s modulus, strain-to-failure, and fatigue stren...
متن کاملInfluence of primary precipitate shape, size volume fraction and distribution in PM tool steels on galling resistance
In sheet metal forming (SMF), the major failure reason is galling. Galling is a process of different wear stages that leads to destruction of both the forming tool and the sheet metal working piece and is, because of that, of big economic importance for the SMF industries. Therefore, investigations and researches about how tool steels microstructure affect the tool steels galling resistance is ...
متن کاملA Critical Assessment of First Principles Inputs for Modeling RIS in Austenitic Fe-Cr-Ni Steels
Radiation induced segregation (RIS) in austenitic Fe-Cr-Ni steels is a widely studied but incompletely understood process important for reactor components. Experimental studies have shown that Cr depletes strongly at grain boundaries, giving rise to corrosion resistance issues. Various research throughout the years has produced models that make specific assumptions about the dominant mechanisms...
