Transformation Plasticity and Toughening
Analysis of the dynamic evolution of multilevel structure during martensitic transformations provides kinetics-based constitutive relations for transformation plasticity. Application in numerical modeling of ductile fracture by microvoid-softening-induced shear localization, in conjunction with metallographic study of crack-tip processes, identifies transformation toughening mechanisms operatin...
متن کاملInvestigation 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 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...
متن کاملMartensitic transformation plasticity simulations by finite elements
The mechanical behaviour associated to the martensitic transformation has been modelled using a 2D FE description. The martensite variants are constituted of different elements of the mesh and four different variants are allowed to transform in the grain. The transformation progress is prescribed using a thermodynamical criterion based on the maximal work associated to the variant formation. Tr...
متن کاملTensile Transformation-Mismatch Plasticity of Bismuth Sesquioxide
This study reports on experiments where bismuth sesquioxide (Bi2O3) was cycled between its high-temperature d-phase and one or more of its low-temperature phases (a-, b-, or g-Bi2O3) while being subjected to uniaxial tensile stresses in the range of 0.11–0.55 MPa. Reproducible strain increments of 0.4%–3.9% have been measured after each thermal cycle, and total tensile fracture strains of 10%–2...
