Review: Low transformation temperature weld filler for tensile residual stress reduction
TL;DR: In this paper, an attractive alternative approach for the reduction of harmful residual stresses in weld zones is reviewed, which utilises low temperature, solid-state, displacive phase transformations in steel.

Strengthening and mechanical stability mechanisms in nanostructured bainite
Behzad Avishan,Carlos Garcia-Mateo,Lucia Morales-Rivas,Sasan Yazdani,Francisca García Caballero +4 more
TL;DR: In this paper, the main relationships between the microstructure parameters controlling the strength and ductility of low temperature bainitic microstructures are discussed. But the authors focus on the mechanical stability of retained austenite.

Effect of chemical composition, martensite volume fraction and tempering on tensile behaviour of dual phase steels
TL;DR: In this article, an investigation was conducted into the tempering effects on mechanical properties of a carbon steel and a microalloyed steel, both with dual phase microstructure.

Three-dimensional atom probe characterization of alloy element partitioning in cementite during tempering of alloy steel.
TL;DR: Three-dimensional atom probe analyses of the AISI/SAE 4340 steel show that Si rejection from the cementite is first detected after low-temperature tempering for times of 1 h, and that Mn and Cr contents are increased, and Ni contents decreased, in cementite according to their carbide- and non-carbide-forming tendencies, respectively.

HSLA-100 steels: Influence of aging heat treatment on microstructure and properties
TL;DR: In this paper, a new family of high-strength low-alloy steels with copper additions (HSLA-100) has been developed, which includes a reduction in the carbon content, which improves toughness and weldability.
