A method for evaluating thermophysical properties of metal alloys Simulation of the solidification of metal alloys, a key step in certain industrial processes, requires reliable data on their thermophysical properties such as surface tension and viscosity. Researchers propose comparing predictive models with experimental outcomes as a method to assess these data. Scientists use data on surface tension and viscosity of titanium-based alloys in industrial processes such as casting and crystal growth. Non-Equilibrium Solidification, Modelling for Microstructure Engineering of Industrial Alloys, an ESA (European Space Agency) investigation, examined the microstructure and…

NASA’s Webb Reveals Smallest Asteroids Yet Found in Main Asteroid Belt
Illustration of the main asteroid belt, orbiting the Sun between Mars and Jupiter NASA NASA’s powerful James Webb Space Telescope includes asteroids on its list of objects studied and secrets revealed. A team led by researchers at the Massachusetts Institute of Technology (MIT) in Cambridge repurposed Webb’s observations of a distant star to reveal a population of small asteroids — smaller than astronomers had ever detected orbiting the Sun in the main asteroid belt between Mars and Jupiter. The 138 new asteroids range from the size of a bus to the size of a…

Benchmarks for solidifying metal alloys Researchers report benchmark data for modeling the growth of specific types of microstructures that form during solidification of metal alloys under different conditions. These microstructures affect the properties of materials and products such as refrigeration devices and solar cells. The ESA (European Space Agency) Columnar-to-Equiaxed Transition in Solidification Processing (CETSOL) investigation studied the processes of metal alloy solidification and the crystal patterns that form as liquids transition to solids. Results could improve ground-based development of lightweight, high-performance structural materials for space and ground applications. Microgravity…
