Compound Formation And Microstructure Of As-Cast High Entropy Aluminums
(MDPI, 2018-03-09)
The aim of this work is to study the microstructure of four high entropy alloys (HEAs) produced by large scale vacuum die casting. Al40Cu15Mn5Ni5Si20Zn15, Al45Cu15Mn5Fe5Si5Ti5Zn20, Al35Cu5Fe5Mn5Si30V10Zr10, and ...
Solid Fraction Determination at the Rigidity Point by Advanced Thermal Analysis
(MDPI, 2021-11-27)
The aim of this work is to determine the Solid Fraction (SF) at the rigidity point (FRP) by applying advanced thermal analysis techniques. The variation of the FRP value is important to explain the solidification behavior ...
