ULTRA FINE FERRITE FORMATION IN Si-Mn TRIP STEELS
Abstract: In the present investigation, the effects of thermomechanical processing parameters and the steel chemical composition on the ultra fine ferrite formation characteristics were studied. This was programmed relying on the capabilities of strain induced transformation (SIT) phenomenon and applying to different grades of Si-Mn TRIP (Transformation Induced Plasticity) steels. According...
متن کاملUltra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
متن کاملEffect of particle size on the flocculation behaviour of ultra-fine clays in salt solutions
Currently, two commercial plants are operating to produce ~20% of Canada's petroleum requirements from the Athabasca oil sands deposit in Alberta. The hot water extraction process is used to extract the bitumen from this resource. During processing, mechanical dispersion forces cause mobilization of ultra-fine clays into the process water (Kotlyar et al., 1992a, 1993). The resulting slurry is t...

متن کاملDynamics in fine particle magnets
Several magnetic fine particle systems have been studied with selective excitation double Mössbauer ~SEDM! spectroscopy. Static disorder, collective excitations, and superparamagnetic spin flips are all detected and their contributions quantified. Zero-field muon spin relaxation spectroscopy has been used to confirm these observations in one sample. A theoretical description of SEDM spectra in ...
