Thixotropy of semisolid metals
(Materials Research Society, 2000)Understanding the time-dependent flow behavior of metal alloys in semisolid state is essential for the further development of the process. In the present investigation, the thixotropic behavior of semisolid slurries is ...

Three dimensional flow of thixotropic materials in a channel with a sudden expansion using a phenomenological constitutive relation
(Affiliation: WPI, Worcester, United StatesCorrespondence Address: Alexandrou, Andreas N.WPI, Worcester, United States, 1996)A constitutive relation is proposed that is capable of predicting a wide range of experimental rheological behavior depending on the proper choice of the parameters. The model represents the otherwise discontinuous Bingham ...

Time-dependent rheology of semisolid metal suspensions
(Affiliation: Metals Processing Inst, Worcester, United StatesCorrespondence Address: Burgos, Gilmer R.Metals Processing Inst, Worcester, United States, 1999)Understanding the time-dependent flow behavior of semisolid materials (SSM) is essential for the simulation of semisolid processes. During processing, the structure of the material changes with the processing history due ...

Yield behavior of commercial Al-Si alloys in the semisolid state
(2004)Systematic experimental work and modeling efforts have been conducted to characterize the yield behavior of commercial aluminum alloys in the semisolid state. In this study, extensive compression experiments were performed ...
