      Parameter estimation for semi-solid aluminum alloys using transient experiments 

      Alexandrou, Andreas N.; Georgiou, G.; Tonmukayakul, N.; Apelian, D. (2006)
      A rotating vane-cup rheometer is used to determine the rheological properties of semi-solid slurries, and a procedure is established for characterizing the rheology with emphasis given to the proper and self-consistent ...
