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...
متن کاملWeldability 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...
متن کاملWeldability 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...
متن کاملControl of weldability
The understanding of the hardenability is important in steel development with respect to weldability of steels as well as to the design of quenched and tempered steels. The common way to judge if steel is suitability to welding is the use of a carbon equivalent, which reflects the alloy content to the hardenability of the heat affected zone (HAZ). Most common of these equivalents is the IIW car...
متن کاملConstructional Meaning and Compositionality
One of the major motivations for constructional approaches to grammar is that a given rule of syntactic formation can sometimes, in fact often, be associated with more than one semantic specification. For example, a pair of expressions like purple plum and alleged thief 25 call on different rules of semantic combination. The first involves something closely related to intersection of sets: a pu...
