How Metal induces crystallisation
Closed  Responses: 0
In a PECVD deposited aSi 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...

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.

CastaBox: Casting Conditions and Macroporosity
07 Apr 2019   Contributor(s):: Adam Powell
An illustration of threedimensional 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...
