Weldability of Thermomechanically Treated Steels Having a High Yield Point

Spot weldability of TRIP assisted steels with high carbon and aluminium contents

We examine here the spot welding characteristics of transformation induced plasticity assisted steels, which contain d-ferrite as a consequence of their aluminium concentrations of 3?5 or 5?6 wt-% and which also have high carbon contents of 0?3 or 0?4 wt-% when compared with conventional automotive steels. The resistance spot welds are tested in both shear and crosstensile tests in order to det...

Weldability and Monitoring of Resistance Spot Welding of Q&P and TRIP Steels

This work aims at investigating the spot weldability of a new advanced Quenching and Partitioning (Q&P) steel and a Transformation Induced Plasticity (TRIP) steel for automotive applications by evaluating the effects of the main welding parameters on the mechanical performance of their dissimilar spot welds. The welding current, the electrode tip voltage and the electrical resistance of sheet s...

Assessing the Yield Point of Concrete Steels Based upon Known Chemical Composition

The incorporation of recycling, which is the production of raw materials from old buildings and devices, is an increasing trend in industries worldwide. This increase in recycling is motivated by the conservation of energy and environmental resources, in particular, the decrease of carbon dioxide and green house gas emission by the intensive burning during various technological processes. The p...

Crystal Plasticity Constitutive Model for Multiphase Advanced High Strength Steels to Account for Phase Transformation and Yield Point Elongation

Weldability Comparison of Tritium-charged-and-aged 304 and 316ln Stainless Steels

Measurement of the effects of helium (from tritium decay) on the weldability of Types 304 and ITER Grade 316LN stainless steel demonstrated the inherent complexities in designing and conducting an experimental program using tritium-charged-and-aged materials to simulate the effects of irradiation-induced helium on weld behavior. Differences in microstructure, surface condition and alloy chemist...
