This project aims to characterise critical microstructures within engineering metals using ultrasound. Such grain microstructures fundamentally determine the critical performances of the polycrystalline metals. However, there is a lack of effective methods to characterize them in the volume, with current standard measurement restricted to destructive, two-dimensional section surfaces of sacrificial samples, which remains laborious, costly and inaccurate. Therefore, ultrasound has been pursued as an alternative.

该项目旨在利用超声波表征工程金属内的关键微观结构。这种晶粒微观结构从根本上决定了多晶金属的关键性能。然而，缺乏有效的方法来表征它们的体积，目前的标准测量仅限于牺牲样品的破坏性二维截面表面，这仍然费力、昂贵且不准确。因此，人们一直在寻求超声波作为替代方案。
