steel research international, EarlyView.A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

steel research international, EarlyView.Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

steel research international, EarlyView.The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Heat Treatment of Closed-Die Forgings of Low-Alloy AHSS Steels
, 2018 New methods are sought today for improving the mechanical properties of heavy-duty parts of high-strength steels, particularly in the automotive industry. AHS steels tend to be associated with high strength and hardness, which are achieved at the cost of poor ductility.

Using the particle finite element method for predicting edge-cracking in complex phase high-strength steel sheets [PDF]
MATEC Web of ConferencesAdvanced High-strength steel (AHSS) sheets enable lightweight designs by reducing material thickness while retaining necessary structural properties. However, their high strength often complicates forming operations and increases vulnerability to defects

A novel method for the spring-back analysis of a hot stamping steel
Journal of Materials Research and Technology, 2021 Spring-back of sheet metal affects the dimensional accuracy of the components after stamping and has to be eliminated or corrected. Advanced high strength steels (AHSS) are prone to spring-back while forming at ambient temperatures.

ANZ Journal of Surgery, EarlyView.ABSTRACT Background Wide‐awake local anaesthesia no tourniquet (WALANT) is increasingly used globally for hand surgery, offering clinical and operational benefits. However, its adoption in Australia remains understudied. This study assessed current WALANT usage among Australian hand surgeons to identify key factors influencing its implementation ...
