Beyond my primary focus on metastable monotectic alloys, I have collaborated on several research projects investigating the behaviour of intermetallic compounds under rapid solidification in microgravity conditions. These studies contribute to a broader understanding of phase transformations, microstructural evolution and mechanical behaviour in different alloy systems under extreme solidification environments.
Below are selected publications from these collaborative research efforts:
Presence of έ and ε Crystal Structures in Rapidly Solidified Intermetallic Compound Ni₅Ge₃
Published in Journal of Alloys and Compounds , 2021
This study explores the rapid solidification of the intermetallic compound Ni₅Ge₃ under microgravity-like conditions, revealing the formation of έ and ε crystal structures. Using drop-tube experiments, we analysed the phase evolution and transformation mechanisms, shedding light on how cooling rates influence metastable phase formation. The findings contribute to a deeper understanding of phase stability in intermetallic systems, with potential applications in high-temperature materials and coatings.

The Development of Plate and Lath Morphology in Ni₅Ge₃
Published in Physics of Metals and Metallography, 2021
This research investigates the morphological evolution of Ni₅Ge₃ during rapid solidification, focusing on the formation of plate and lath structures. By correlating solidification kinetics with microstructural patterns, we provide insights into the interplay of nucleation dynamics and growth modes. The study advances knowledge on microstructural control in intermetallic alloys, which is crucial for optimizing mechanical performance in engineering applications.
