The formation of precipitates during thermal processing of microalloyed steels greatly influences their mechanical properties. Precipitation behavior varies with steel composition and temperature history and can lead to beneficial grain refinement or detrimental transverse surface cracks. This work presents an efficient computational model of equilibrium precipitation of oxides, sulfides, nitri...

Fine-grained steels, which belong to the HSLA (High-Strength Low-Alloy) group of are increasingly used for parts statically and dynamically loaded constructions. Due thermal effect welding, combined with inherent stiffness clamping part, residual stresses generated in HAZ (heat-affected zone) affect fatigue life sub-weld entire construction. In this article, a specific temperature cycle measure...

Steels applied in the automotive industry can be classified under the AHSS category, which includes dual-phase (DP) steels, complex-phase (CP) steels and transformation-induced plasticity (TRIP) steels. The UHSS category mainly includes martensitic steels. The above-mentioned steel groups are well pressable, show an excellent combination of strength, service life and absorption of strain energy...
