Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

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.

Damage Investigation of the Preform Operations for the Production of Rings for Ring Rolling

steel research international, EarlyView.
Void evolution during the preforming operations of two industrial ring rolling process routes is investigated by combining metallographic characterization with a two‐scale finite element simulation approach. The results reveal that, despite differing initial void conditions, the preforming operations can be designed to effectively influence void ...

Experimental and theoretical investigation of longitudinal tunnel lining joints with confining reinforcement

Structural Concrete, EarlyView.
Abstract Precast reinforced concrete segmental linings are frequently used in modern tunneling. In these linings, the longitudinal joints typically have a reduced contact cross‐section and thus often govern the design, particularly in tunnels under high hydrostatic pressure or crossing squeezing or swelling ground with correspondingly high ...

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

Structural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...
