The Effect of Nb on the Continuous Cooling Transformation Curves of Ultra-Thin Strip CASTRIP© Steels
Metals, 2015 The effect of Nb on the hardenability of ultra-thin cast strip (UCS) steels produced via the unique regime of rapid solidification, large austenite grain size, and inclusion engineering of the CASTRIP© process was investigated.

Journal of Materials Research and Technology, 2022 Pulsed direct current (PDC) gas tungsten arc welding (GTAW) of 12 mm thick plates of naval, marine-grade high strength low alloy steel (HSLA) using ER80S–Ni3 filler metal was investigated. The microstructural characteristics were examined by both optical

Mechanism of the Transition from Bainite to Acicular Ferrite
Materials Transactions, JIM, 1991 The factors controlling the transition from a microstructure consisting of austenite grain boundary nucleated sheaves of bainite, to one containing intragranularly nucleated plates of acicular ferrite are explored. The work confirms that in weld metals containing inclusions, the transition from bainite to acicular ferrite can be stimulated of the prior

Microstructures and Mechanical Properties of Q345B Steel Weld Joint Using Double sided Arc Welding
Journal of Harbin University of Science and Technology, 2018 To solve the problem of incomplete penetration and the welding torch hitting the plate during the welding process of Q345B large thick plate by using robot double-sided arc welding，the method of using no reserved-clearance root was proposed.

steel research international, EarlyView.This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

steel research international, EarlyView.This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...
