Mechanical Behavior of a Twip Steel (Twinning Induced Plasticity)
(Univ Fed Rio de Janeiro, 2015-07)
A TWIP steel (0.65%C; 22%Mn; 0.28%Cr; 0.16%Si) was produced in the laboratory by melting, casting, hot forging and hot rolling. The relationship between mechanical twinning fraction and mechanical behavior of this steel ...
Temperature Dependence of the Microstructure and Mechanical Properties of a Twinning-Induced Plasticity Steel
(Multidisciplinary Digital Publishing Institute, 2018-04)
The objective of the present study is to analyze the microstructure and mechanical properties of a twinning-induced plasticity (TWIP) steel at different temperatures. For this purpose, tensile tests were performed on a ...
Interface-Mediated Twinning-Induced Plasticity in a Fine Hexagonal Microstructure Generated by Additive Manufacturing
(Wiley VCH Verlag, 2021-10)
The grain size is a determinant microstructural feature to enable the activation of deformation twinning in hexagonal close-packed (hcp) metals. Although deformation twinning is one of the most effective mechanisms for ...
In Situ High-Energy Synchrotron X-Ray Diffraction Reveals the Role of Texture on the Activation of Slip and Twinning during Deformation of Laser Powder Bed Fusion Ti–6Al–4V
(Wiley VCH Verlag, 2021-05)
The deformation behavior of Ti–6Al–4V processed by laser powder bed fusion (LPBF) is investigated by in situ high-energy synchrotron X-ray diffraction (HEXRD) during uniaxial compression. The initial microstructure of the ...
Molecular dynamics simulations of shock-induced deformation twinning of a body-centered-cubic metal
(American Physical Society, 2013-09-17)
Despite a number of previous nonequilibrium molecular dynamics (MD) studies into plasticity in face-centered-cubic metals, and phase transitions in body-centered-cubic (bcc) metals, the plastic response to rapid compression ...
Molecular dynamics simulations of shock-induced plasticity in tantalum
(Elsevier, 2013-10)
We present Non-Equilibrium Molecular Dynamics (NEMD) simulations of shock wave compression along the [001] direction in monocrystalline Tantalum, including pre-existing defects which act as dislocation sources. We use a ...
Effects of Strain Rate on the TRIP–TWIP Transition of an Austenitic Fe-18Mn-2Si-2Al Steel
(Springer, 2019-09)
A fully austenitic Fe-18Mn-2Si-2Al transformation-induced plasticity (TRIP) steel was tensile tested from quasi-static to low-dynamic regime at three different strain rates: 4.7 × 10−4, 1.3 × 10−1, and 8.3 × 100 s−1. Typical ...
Análise do comportamento mecânico e estudo do efeito de maclação mecânica do aço 316 LV sob estados de tração e compressão
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Mecânica - PPGEMecCâmpus São Carlos, 2022-11-23)
The design of new steels with high yield, ultimate strength and good ductility is one of the desirable goals of the industry. The ultra-high strength steels with twin induced plasticity (TWIP) effect are used in applications ...
Avaliação do processamento de aço trip-twip em escala piloto
(Universidade Federal de Minas GeraisUFMG, 2014-12-12)
Currently, the structure of automobiles is composed of different types of steels, according to the specific function of each component. Parts that require high mechanical strength are produced with conventional high-strength ...
