Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

open access: yessteel research international, EarlyView.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

Thermodynamic Modeling of Sn–C and Fe–Sn–C Systems for the Tramp Elements Control in Steel Production

open access: yessteel research international, EarlyView.
A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

Effect of Repeated Austenitisation and Cooling on the Microstructure, Hardness and Tensile Behaviour of 0.16 wt % Carbon Steel [PDF]

open access: yesArchives of Metallurgy and Materials, 2018
Repeated austenitisation and furnace cooling of homogenised 0.16 wt. % carbon steels result in ferrite grain sizes between 27 μm and 24 μm. Similarly, repeated austenitisation and normal-air cooling produces ferrite grain sizes between 17 μm and 12 μm ...

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

open access: yessteel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

Fracture surface microstructure and new fracture mechanism in the pearlite structure

open access: yesJournal of Materials Research and Technology
The fracture behaviours of pearlite structures in several typical carbon steels were investigated by scanning electron microscopy (SEM). Microstructural analysis indicated that the fracture of pearlite is a mixed ductile-brittle fracture, and brittle ...

Effect of the morphology of the martensite-austenite phase on fracture of the weld heat affected zone in vanadium and niobium microalloyed steels [PDF]

open access: yes, 2010
In multipass welding, the intercritically reheated coarse grained heat affected zone demonstrates the worst toughness in welded joint, since it contains a high-carbon martensite with some retained austenite, known as M-A phase, which is brittle and ...

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design

open access: yessteel research international, EarlyView.
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...

Influence of Cooling Rate and Sn Addition on Microstructure Formation of As-cast GCD700 Spheroidal Graphite Cast Irons [PDF]

open access: yes한국정밀공학회지
This study investigated the influence of cooling rate and Sn addition on the microstructure formation of as-cast GCD700 spheroidal graphite cast irons. Changes in cooling rate manifested as step cast thickness differences.
