Nitrate and nitrite reduction by ferrous iron minerals in polluted groundwater: Isotopic characterization of batch experiments
(2020-08-20)
Article
Restricted access - publisher's policySince nitrate (NO3-) has been related to human health and environmental problems, safe and sustainable strategies to remediate polluted water bodies must be investigated. This work aims to assess the feasibility of using ... -
Superficial effects of ball burnishing on TRIP steel AISI 301LN sheets
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-03)
Article
Open AccessThis paper explores the consequences of applying an ultrasonic vibration-assisted ball burnishing process and its non-vibration assisted version on the topology and subsurface microstructure of a transformation-induced ... -
Prediction of mechanical properties of human rib cortical bone using fractal dimension
(Gordon and Breach Science Publishers, 2020-10-26)
Article
Restricted access - publisher's policyA large number of post mortem human subjects was used to investigate the relation between the micro-structure of rib cortical bone and the mechanical properties using Fractal Dimension. Uniaxial tensile tests were performed ... -
Investigation on texture evolution and recrystallization aspects of novel Mg–Zn–Gd–Y–Nd alloys
(2020-05-11)
Article
Restricted access - publisher's policyMagnesium exhibits substantial property enhancement for a vast range of applications via alloying by rare earth elements (REs). The effect of different amounts of alloying elements (Zn and REs such as Gd, Y and Nd) on the ... -
Thermal analysis of CuMg alloys deformed by equal channel angular pressing
(Springer, 2020-08-05)
Article
Open AccessThe thermal behavior of two copper alloys, with 0.2 and 0.5 mass % of Mg, was analyzed after severe plastic deformation processing by Equal Channel Angular Pressing (ECAP). Both alloys were forced to be passed through a ... -
Microstructural effects on fracture toughness of ultra-high strength dual phase sheet steels
(2021-01-20)
Article
Open AccessThe influence of the microstructure on the fracture toughness of two industrially processed 1000 MPa dual-phase (DP) steel grades is investigated. Crack initiation and propagation resistance are evaluated by means of the ... -
Fracture resistance of advanced high-strength steel sheets for automotive applications
(2021-01-03)
Article
Open AccessThe fracture resistance of different advanced high strength steel (AHSS) sheets for automotive applications is investigated through conventional tensile tests, fracture toughness measurements and hole expansion tests. ... -
A dislocation assisted self-consistent constitutive model for the high-temperature deformation of particulate metal matrix composite
(Taylor & Francis, 2021-01)
Article
Restricted access - publisher's policyA dislocation assisted self-consistent model based on Tandon and Weng approach and Bergstrom dynamic recovery model for particulate-reinforced composites has been extended to consider the matrix evolution during high-temperature ... -
Prediction of generation of High- and Low-Angle Grain Boundaries (HAGB and LAGB) during severe plastic deformation
(2020-06-20)
Article
Restricted access - publisher's policyIt is well known that a balance between the generation of low-angle and high-angle grain boundaries (LABG and HAGB) is achieved in materials undergoing a severe plastic deformation (SPD) process. It is also observed that ... -

Article
Restricted access - publisher's policyIn recent years there has been an increase in the field of research of advanced steels that have excellent mechanical properties combining high strength with excellent ductility. Within this range of advanced steels are ... -
Strain hardening behavior in an AA6060-T6 alloy processed by ECAP
(2020-09)
Article
Restricted access - publisher's policyStrain hardening is a useful mechanism for improving mechanical properties in materials. This study investigates the strain-hardening behavior of an AA6060 alloy processed by equal channel angular pressing (ECAP) up to 12 ... -
FE thermo-mechanical simulation of welding residual stresses and distortion in Ti-containing TWIP steel through GTAW process
(Elsevier Ltd, 2020-11)
Article
Restricted access - publisher's policyThe effect of residual stresses can be beneficial or harmful depending on their magnitude, type and distribution. This research work applied the isotropic and kinematic hardening models with different strain rates (0.001-100 ...
