  1. How Metal induces crystallisation

    Closed | Responses: 0

    In a PECVD deposited a-Si we crystallize them by annealing method at a temperature of above 873K. But when a metal is induced say Aluminium, the crystallization starts at 393K. What is the...

  2. Bottom Filled Mold

    07 Apr 2019 | | Contributor(s):: Matthew John M. Krane

    Calculation of mold filling times, with and without a constant height of metal in a riser. Problem uses modified Bernoulli equation for the mechanical energy balance and the students are asked to determine which resistances are significant.

  3. Cast-a-Box: Casting Conditions and Macroporosity

    07 Apr 2019 | | Contributor(s):: Adam Powell

    An illustration of three-dimensional finite difference simulation of heat conduction with phase change and complex boundary conditions, this requires students to adjust boundary conditions to make the top surface of a regular hexahedral "casting" to freeze last, eliminating...
