Journal ArticleDOI
Experimental and modeling investigation of the failure resistance of Advanced High Strength Steels spot welds
TL;DR: In this article, three main failure mechanisms and failure zones are identified: (i) strain localization in the base metal/subcritical Heat Affected Zone (HAZ), (ii) ductile shear around the weld and (iii) semi-brittle fracture in the weld nugget.
Journal ArticleDOI

TL;DR: In this paper, the heat affected zones (HAZ) of two dual-phase steels spot welds, DP450 and DP980, were investigated experimentally with a Gleeble 3500 thermomechanical simulator.
Journal ArticleDOI
Comparison of the evaluation of the carbon content in solid solution in extra-mild steels by thermoelectric power and by internal friction
TL;DR: In this article, a comparison of the carbon content in solid solution in extra-mild steels by thermoelectric power (TEP) and by internal friction (IF) showed the existence of a population of carbon atoms, which is not detected by IF but is visible by TEP.
Journal ArticleDOI
Investigation of the Tensile Shear fracture of Advanced High Strength Steel spot welds
TL;DR: In this article, two main failure mechanisms and failure zones are identified: (i) strain localization in the base metal/subcritical Heat Affected Zone (HAZ), (ii) ductile shear at the interface in the weld nugget.
