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

2. Rapid solidification behaviour of Fe and Al based alloys
Abstract : Rapid solidification experiment on Fe-Cr-Mo-Mn-Si-C alloy was performed to investigate metastable phases formed during the solidification. A wide range of cooling rate was used to analyse the sample from melt spinning technique (~107 K/s) to water quenching method (~102 K/s). READ MORE

3. On the hot crack formation during solidification of iron-base alloys
Abstract : Hot cracking during solidification is a severe problem inmany casting processes, for example in continuous casting.Combinations of low strength and low ductility of the materialat high temperatures and applied tensile stress can cause hotcracking. READ MORE

4. Slag inclusion formation during solidification of steel alloys and in cast iron
Abstract : This thesis explores the formation of segregation and inclusions during solidification of steel and cast iron. A better understanding of the formation mechanism should result in decreasing fraction of defects during solidification of ingot and strand material. READ MORE

5. Characteristics of cast magnesium alloys : microstructures, defects and mechanical properties
Abstract : Magnesium is the lightest of all structural metals. As such, and combined with good mechanical and physical properties, it forms the basis for commercial alloys that have found successful use in a wide variety of applications. READ MORE
