Transformers typically emit a low-frequency humming noise, which can be a major obstacle for their use in urban areas. This acoustic noise is caused by mechanical vibrations of the magnetic…
Read moreThanks to our expertise in finite element simulation, our in-depth knowledge of steel grades and of the deep-drawing process, OCAS selects the best solution – thickness and steel grade selection…
Read moreWhen striving for material and process optimisation, traditional constitutive mechanical material models lack knowledge on material microstructural parameters such as grain size, shape, orientation, etc. Whereas micromechanical models are reliable…
Read moreA request for technical support from an offshore gas pipeline customer highlighted the importance of the effect of filler wire selection on weld metal toughness. This triggered OCAS to set…
Read moreFinite element analysis helps to reduce development time and limits technical and budgetary risks. The acquired know-how on modelling rolling processes allows anticipating difficulties or proposing modifications whenever new compositions…
Read moreThe use of high-strength steel in structural components is becoming more and more attractive. For weight-saving reasons, typical applications include telescopic cranes, tippers, trucks and trailers. However, in spite of…
Read moreBeing able to produce more samples much quicker means that smart sample handling and fast characterisation are needed to identify materials with potential for further fine-tuning.
Read moreFor breakthrough product developments, where few reference data are available, a massive number of compositional ranges need screening prior to selecting the interesting chemistries. OCAS believes that combinatorial methodologies significantly…
Read moreNitriding as thermochemical treatment on the final material can be used to significantly improve surface and bulk properties.
Read moreNitrogen is present in all steels as residual element. In some cases however, nitrogen is wanted and added intentionally as alloying element. Depending on the steel composition, this results in…
Read moreMastering both surface pre-treatment as well as plating, OCAS's experts provide coating solutions for different types of wire.
Read moreMetallic coating development takes a long time and is expensive because of the long-term corrosion testing in both lab and outdoor conditions. So, simulation-assisted engineering could lead to significant acceleration…
Read moreSince 2005, OCAS has been building up hydrogen research competence systematically in order to serve the needs related to modern technological developments, i.e. hydrogen as an energy vector, the industrialisation…
Read moreMany structures and components are used longer than their design life, or operate in conditions different from what was originally expected. As consequence, defects like cracks can be present and…
Read moreThanks to its multi-wire submerged arc welding (SAW) facility, OCAS is able to develop welding guidelines for the most demanding applications in the energy sector. All data on steel properties…
