Abstract S500MC steel is a grade of high-strength low-alloy (HSLA) which widely used in the automotive industry and for agricultural machinery equipment. Considering properties this alloy, selection welding process parameters becomes essential to ensure that HSLA assemblies meet specific service requirements. In work, mechanical metallurgical produced by autogenous laser beam (LBW) automatic ga...

Solubility of mixed niobium-titanium carbonitrides in commercially relevant High-Strength Low-Alloy (HSLA) steel was investigated by combined use electrical resistivity measurements and APT after interrupted quenching from soaking temperatures between 950 1250 °C. Increasing the bulk material towards higher proportional to nominal niobium addition which varied 0.002 0.022–0.043–0.085 wt.-%. Cor...

Zn-Al-Mg coatings are important materials for the corrosion protection of steel sheets. However, susceptibility towards cracking limits formability performance these coatings. In this study, we focus on effect underlying substrate behavior in order to elucidate this, a high-strength low-alloy (HSLA) and an interstitial-free (IF) coated with two different ZnAlMg without binary eutectic microstru...

The parent material (PM) and s...

This study presents a probabilistic, 3-D framework to describe brittle fracture in structural components which incorporates weakest link statistics and a micromechanics model reflecting local damage of material. The Weibull stress (a,) emerges as a fracture parameter to define conditions leading to local material failure. This parameter is correlated with the macroscopic loading and used to des...

In order to assess the integrity of welded pressure vessel containing a crack, behavior three-point bending specimens made HSLA steel joint are tested at -40°C, and their fracture behaviour analyzed, as conservative measure crack resistance. Specimens were low-alloyed NIONIKRAL 70, by SAW process. Surface notches machined electro-erosion method in parent metal (PM), heat affected zone (HAZ) wel...
