1. High performing cast aluminium-silicon alloys
Abstract : The need to produce lighter components due to environmental aspects and the development of electrical vehicles represents an opportunity for cast aluminium-silicon alloys. With high specific strength, good castability, high corrosion resistance and recyclability, these alloys offer an attractive combination of properties as an alternative to steel, cast iron and titanium-based components in certain applications.

3. A critical survey of the grain refining mechanisms of aluminium
Abstract : In the present work, several possible interpretations of the grain refining mechanisms of aluminium castings after additions of titanium and boron are compared with the results of critical test experiments. The presence of B does not seem to affect the binary Al-Ti phase diagram close to the A1 comer, except for formation of boride phase. READ MORE

4. On particles and slags in steel casting
Abstract : Hadfield steel is widely accepted as one of the most important steel alloys utilized in industrial applications where high impact strength and wear resistance is required. Like in most metallic alloys used for component casting, the mechanical properties of Hadfield steel are directly connected with the microstructure of the material. READ MORE
