RESEARCH OBJECTIVES
Columnar-to-Equiaxed Transition in Solidification Processing-2 (CETSOL-2) investigation aims to
deepen the understanding of the physical principles that govern solidification processes in
metal alloys. The patterns of the crystals resulting from transitions of liquids to solids is of
substantial importance to processes in producing materials such as solar cells, thermoelectrics,
and metal alloys.
EARTH BENEFITS
The transport industry is keen to use data from CETSOL-2 to reduce weight and increase
strength of aircraft and road vehicles.
SPACE BENEFITS
Metal foams are already being used in cars and cranes and research on the International Space
Station and is helping to develop newer alloys which can also be used for spacecraft materials
and constructions.
This investigation is ongoing and additional results are pending publication.
