Equilibrium Model of Precipitation in Microalloyed Steels
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...
متن کاملParticle-Size-Grouping Model of Precipitation Kinetics in Microalloyed Steels
The formation, growth, and size distribution of precipitates greatly affects the microstructure and properties of microalloyed steels. The computational Particle-Size-Grouping (PSG) kinetic models were developed to simulate precipitate particle growth due to collision and diffusion mechanisms. Firstly, the standard PSG method for collision is clearly explained and verified. Then a new PSG metho...
متن کاملEffect of NbMo Addition on the Precipitation Behaviour of V Microalloyed Steel during Intercritical Annealing
This paper reports on the precipitation behaviour and microstructural evolution in ~20% cold rolled NbMoV and V single microalloyed low carbon steels during intercritical annealing. The microstructure and precipitation behaviour were studied by optical and scanning/transmission electron microscopy and microanalysis, X-ray diffraction technique and Vickers hardness testing. After intercritical a...
متن کاملEvolution of nanoscale precipitates in Al microalloyed with Sc and Er
The coarsening kinetics of nanoscale, coherent Al3ð Sc1 xErxÞ precipitates in a-Al during aging of a supersaturated Al–0.06 Sc–0.02 Er (at.%) alloy at 300 C are studied using transmission electron microscopy and local-electrode atom-probe tomography. Erbium and Sc segregate at the precipitate core and shell, respectively. The matrix supersaturations of Er and Sc, as well as the mean precipitate...
متن کاملHeat affected zone microstructures and their influence on toughness in two microalloyed HSLA steels
Microstructures and Charpy impact properties have been examined in two microalloyed steels following heat treatments to simulate weld heat affected zone (HAZ) structures over a range of heat input conditions, characterised by the cooling time from 800 to 500 !C (Dt8/5). The base materials were low carbon structural steel plates microalloyed with vanadium and nitrogen (V–N) and niobium (Nb), res...
