The novel quenching and partitioning heat treatment of steel
The recently proposed and novel steel heat treatment process known as quenching and partitioning (Q&P) is studied, in particular, the partitioning stage. Characterization of the partially quenched microstructure prior to the partitioning stage is enabled by using a base composition containing a higher Mn concentration than for conventional Q&P stee...
Development of magnesium-based multilayer PVD coatings for hydrogen storage applications
On the long list of solid-state hydrogen storage materials, magnesium hydride stands out for its relatively high hydrogen storage capacity of 7.7 wt%, combined with the low cost and abundance of magnesium. For practical applications however, issues such as the slow kinetics and the high stability of magnesium hydride must be resolved in order to re...
Characterisation of potential replacements for nickel compounds used in decorative chromium plating
The electroplating industries use soluble nickel salts in numerous applications. Over the past few years this has become problematic due to the reclassification of these salts from a harmful substance to now a toxic substance. The introduction of the legislation REACH (Registration, Evaluation, Authorisation & restriction of CHemicals) has meant th...

Evaluation of spot welding electrodes using digital image processing and image segmentation techniques
The image segmentation algorithm is the most challenging step and requires more computer processing power than the boundary filtering, and the Cullen et al's method, which used the Cullen et al's method to determine the electrodes tip width automatically in the automotive industry in real time. Spot welding is used extensively in the automotive ind...

The mechanical properties of polyester-based coil coatings : correlations with chemical structure
The present work studies the effect of changes in the formulation of coil coatings on their mechanical properties. The paint systems investigated were generally based on polyester binders that were heat-cured with hexa(methoxymethyl)melamine (HMMM). The chemical structure of the polyester, as well as the concentrations of the materials present in t...
Effects of temperature on the adhesive bonding in steel beams reinforced with CFRP composites
The use of carbon fibre reinforced polymer (CFRP) composites in strengthening and repairing steel beams and girders in existing structural bridges has become wide spread in recent years. Though the previous studies had showed significant improvement in the load carrying capacity and the fatigue life of the strengthened structures, they did not take...
