1. Imperfections in Recycled Aluminium-Silicon Cast Alloys
Abstract : In striving to produce high quality cast components from recycled aluminium alloys,imperfections have to be considered, because recycled aluminium usually containsmore of it. However, there are great energy savings to be made by using recycledaluminium; as little as 5% of the energy needed for primary aluminium productionmay be required. READ MORE

2. On the influence of imperfections on microstructure and properties of recycled Al-Si casting alloys
Abstract : There are great energy savings to be made by recycling aluminium; as little as 5% of the energy needed for primary aluminium production may be required. Striving to produce high quality aluminium castings requires knowledge of microstructural imperfections, which is extra important when casting recycled aluminium that generally contains higher levels of imperfections compared to primary aluminium.

3. Beyond Breakaway Corrosion: Investigating the Secondary corrosion protection of Iron-based alloys
Abstract : High temperature corrosion of metallic materials remains a major challenge for many in-dustrial applications. The challenges of high temperature corrosion are often addressed by using highly alloyed materials such as stainless steels or FeCrAl alloys. READ MORE

4. The influence of Al alloy microstructure on conversion coating formation
Abstract : The formation of conversion coatings based on Ce, trivalent Cr and Ti/Zr is triggered by the local pH increase at cathodic IM sites of the aluminium alloy microstructure. The pH gradient is created over the cathodic intermetallic (IM) sites of the microstructure and its intensity is influenced by their activity which depends on their chemical composition, their size, and spatial distribution.

5. Thermodynamic and kinetic properties of Fe-Cr and TiC-ZrC alloys from Density Functional Theory
Abstract : The complete and accurate thermodynamic and kinetic description of any systemis crucialfor understanding and predicting its properties. A particular interest is in systemsthat are used for some practical applications and have to be constantly improved usingmodification of their composition and structure. READ MORE
