Microstructure evolution governing Multi-property enhancement in cold drawn pearlitic steel

Materials & Design
Cold-drawn pearlitic steel wires are extensively used in rope-core drilling under severe conditions, where corrosion and cyclic loading accelerate crack initiation and propagation.

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

steel 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

Microstructure Refinement on Crevice Corrosion of High-Speed Rail Steel U75V Visualized by an In Situ Monitoring System

Frontiers in Materials, 2022
Rail foot covered by a fastener will suffer from crevice corrosion, leading to thinning and localized attack of crevice interior posing a risk of failure. This work investigated crevice corrosion behavior of a typical pearlitic high-speed rail steel U75V,

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

steel 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 ...

Pearlite phase transformation in Si and V steel

Metallurgical and Materials Transactions A, 1995
Systematic research has been undertaken on the effects of single and combined additions of vanadium and silicon on the phase transformation and microstructure of pearlitic steels. Both alloy additions were found to result in the formation of nonlamellar products in the vicinity of austenite grain boundaries in hypereutectoid compositions (0.77 to 0.95 ...

Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

steel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.

Microstructure Characterization of Bending Effects in 304L Stainless Steel Cladded with Low‐Alloy Steel Weld

steel research international, EarlyView.
Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

The effect of microstructure on the initial corrosion behavior of low carbon steel in simulated coal solution

Materials Research Express
The service life of weathering steels in wagon body was determined by their corrosion resistance directly. This study investigated the influence of microstructure on the initial corrosion behavior of low carbon steels, systematically.
