Thixotropic rheology of semisolid metal suspensions
(2001)
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 ...
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 ...
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 ...
Numerical simulation of die filling in semisolid metal processing
(Affiliation: WPI, Worcester, United StatesCorrespondence Address: Bardinet, FrancoisWPI, Worcester, United States, 1997)
Semisolid Metal Processing offers distinct advantages over other near-net-shape technologies, such as a more homogeneous microstructure, less porosity and thus excellent mechanical properties. A perfect control of die ...
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 ...
Numerical simulation of injection mold filling for semi-solid materials
(ASME, 1995)
Processing of metals and metal matrix composites in the semi-solid state is an emerging new technology and is becoming increasingly popular. This method provides several advantages over the traditional liquid state processing ...
Mathematical and computational modeling of die filling in semisolid metal processing
(1999)
A 'Bingham type', or Herschel-Bulkley constitutive relation capable of describing correctly the bulk behavior of the semisolid slurry is introduced. This relation is implemented in a modified version of the casting simulation ...
Transient planar squeeze flow of semi-concentrated fiber suspensions using the Dinh-Armstrong model
(2007)
Numerical simulations are undertaken for the transient squeeze flow between parallel plates under a constant load. The conservation equations are solved via the finite element method in space and the Crank-Nicolson method ...
