Enhanced mechanical properties of martensitic stainless steels resistance spot welds enabled by in situ rapid tempering
TL;DR: In this paper, in situ rapid tempering via applying a second fuse zone was proposed to improve the resistance spot weldability of martensitic stainless steels, which is impaired by the formation of brittle martensite in the fusion zone.

Non-destructive measurement of microstructure and tensile strength in varying thickness commercial DP steel strip using an EM sensor
TL;DR: In this article, an electromagnetic sensor-sample FE model, developed in COMSOL multi-physics software, has been developed to determine the relationship between the low magnetic field relative permeability and microstructure (phase balance and grain size) for commercial dual phase (DP) steel sheets of any thickness.

An integrated-model for austenite yield strength considering the influence of temperature and strain rate in lean steels
Adriana Eres-Castellanos,Isaac Toda-Caraballo,Andreas Latz,Francisca García Caballero,Carlos Garcia-Mateo +4 more
TL;DR: In this article, the authors proposed a more robust model, which includes the contribution of the strain rate and wider composition and temperature ranges by integrating different formulations, providing improvement at predicting yield strength with respect to previous models.

Microstructural investigation of galvanized coatings with prior flash coating of copper on DP steels
TL;DR: In this article, annealing and subsequent galvanizing operations were performed using hot dip simulator and XRD and SEM analysis were done to examine the characteristics of deposited copper layer and different layers in the galvanized coating were investigated in great detail.
