Application of the seeding approach to nucleation in a CaO-SiO₂ system for obtaining the parameters for the Classical Nucleation Theory: A valuable numerical tool for screening potential glassmaking recipes

For the use of screening potential glassmaking recipes the seeding method has been applied to a Molecular Dynamics simulated CaO-SiO₂ system in order to attain the parameters for the Classical Nucleation Theory and construct a Time-Temperature-Transformation (TTT) diagram. Using this TTT diagram, the non-crystallisation temperature and the...

A data-driven heuristic decision strategy for data-scarce optimization: with an application towards bio-based composites

Algorithmic optimization is a viable tool for solving complex materials engineering issues. In this study, a data-scarce Bayesian optimization model was developed to research the composition of bio-based composites. The proof-of-concept program adjusts the natural materials' weight ratios to optimize towards user-defined mechanical properties....

A study of the effect of prior austenite grain size on the microstructure of Quenching and Partitioning steels with Phase-Field Modelling

Quenching and partitioning (Q&P) is a novel processing route that can create microstructures that combine high strength, ductility and easy formability without the excess use of alloying elements by also keeping the production cost low. Therefore, this method is ideal to be applied to steels that are used in the automotive industry. The...

Architectured MIcrostructures: The effect of localized laser heat treatment on the microstructure of a FeCNi steel

Laser surface treatments offer interesting prospects for the creation of architectured microstructures formed by distinct phases in metastable austenitic steels. In the present study, a laser-based localised heat treatment was developed to locally create an austenitic region in a quenched Fe25Ni0.2C martensitic microstructure. The highly...

Effect Of Mechanical Input Energy On Piezoelectric Energy Harvesting

Piezoelectric energy harvesting technology is an alternative source for powering low power electronics. The ability of piezoelectric materials to convert ambient vibrational energy into usable electrical energy is seen as a promising battery-free solution to be used in inhospitable areas to self-power electronics for a longer time with little...
