2. 1. Eutectic Modification of Al-Si casting alloys

   Author : Jenifer Barrirero; Frank Mücklich; Magnus Odén; Franz Jospeh Feikus; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Aluminum alloys with silicon as the major alloying element are the most widely used aluminum casting alloys. The eutectic phase in these alloys is formed by hard and brittle silicon plates in an aluminum matrix. Such silicon plates can act as crack propagation paths deteriorating the toughness of the material. READ MORE

4. 2. Characterization and Modification of Microstructure in Al-Co-Cr-Fe-Ni Eutectic High-Entropy Alloys

   Author : Adrianna Lozinko; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; eutectic alloys; solidification; orientation relationship; high-entropy alloys; microstructure; EBSD; recrystallization;

   Abstract : The recently emerging high-entropy alloys (HEAs) present a novel alloying strategy, significantly expanding the scope of metal alloy design. HEAs are defined as alloys consisting of at least four principal elements in equi- or near equiatomic ratios, with a possibility of small amounts of alloying elements. READ MORE

5. 3. Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperatures
