Microstructure Evolution of HSLA Pipeline Steels after Hot Uniaxial Compression
The mechanical properties of the high-strength low-alloy pipeline steels were mainly controlled by the subsequent phase transformations after rolling. The influence of hot uniaxial compression on the phase transformation of acicular ferrite was explored by viewing of the deformation degree, the deformation temperature, and the strain rate. The results show that the increase of deformation amoun...
متن کاملMicrostructure and mechanical properties of cold rolled, annealed HSLA strip steels
A large testing programme of a strip steel grade, microalloyed by vanadium, titanium and niobium, was conducted. The experiment was based on combination of cold rolling, recrystallization annealing, mechanical testing, metallographic examinations, SEM and TEM analyses. Samples in the form of stripes with dimensions of 3.9×25×500 mm were rolled in several passes with the total height reduction o...
متن کاملConventional and new generation models of microstructure evolution during hot forming of steels
The objective of the paper is discussion of various methods of modelling microstructure evolution during hot forming of steels. Commonly used conventional models based on closed form equations are compared with novel approaches based on artificial neural networks (ANN) and on multiscale models. Predictive capabilities of various models are discussed. Basic principles of the ANN and multiscale m...
متن کاملInfluence of Initial Microstructure on Hot Deformation Behavior of Duplex Stainless Steels
In this research the effect of initial microstructure on hot deformation behavior in terms of Ferrite-to-Austenite ratios is studied. Two types of stainless steels C1 and C2 were homogenizing heat-treated and deformed under hot compression examinations at temperatures 900ºC and 1100ºC at strain rate of 0.1s-1. The results showed that the flow stress levels of specimens are strongly r...
متن کاملStructure and properties of TM processed HSLA steels
This paper deals with the influence of steel composition (with respect to the microalloying elements) and therrnomechanical treatment on structure and mechanical behaviour of HSLA (High Strength Low Alloy) steels. Four different microalloyed steels have been TM rolled under variing conditions. The austenite structure prior to transformation could be revealed by means of a special etching techni...
