Investigation of Transformation Induced Plasticity in High Al–low Si TRIP Steel
This study was conducted in order to investigate the influence of plastic deformation on the transformation of retained austenite in a TRIP steel with a high content of Al and a low content of Si. To the aim, appropriate treatments were used to produce the starting material (TRIP steel). The microstructure of the obtained steel was composed of bainite and phases including ferrite and retained a...
متن کاملAnalysis of banded microstructures in multiphase steels assisted by transformation-induced plasticity
The influence of the spatial distribution of the austenitic phase on the effective mechanical properties of a multiphase steel assisted by transformation-induced plasticity is analyzed using a numerical homogenization scheme. Representative three-dimensional volume elements with distinct microstructures are created applying a newly-developed algorithm based on the generation of a multilevel Vor...
متن کاملLow–Alloy Duplex, Directly–Quenched Transformation–Induced Plasticity Steel
A duplex microstructure consisting of allotriomorphic ferrite and austenite at ambient temperature, has been produced in a low–alloy steel, by a simple heat treatment which involves intercritical annealing followed by quenching. The tensile properties obtained are good, with a total elongation of some 28% at an ultimate tensile strength approaching 900MPa. The form of the stress versus strain c...

متن کاملTransformation Plasticity in Steel Weld Metals
Professor Ulrich Dilthey’s passion for the science and technology of joining processes is amply reflected in the enormous archive of published work which will forever serve the community. It is a pleasure therefore to be able to present this small story as a tribute to someone who has been a scholar, a gentleman and a leader in this most difficult of subjects. The matter of our everyday world i...
