    A simple approach toward quantitative phase field simulation for dilute-alloy solidification

    No full text
    We present a simple approach that could help quantitative phase field simulation for dilute-alloy solidification. The proposed approach mends the solute trapping problem by using a simple interface model (SIM), which requires only one free parameter. To test the feasibility of this model, a free dendritic growth from a small nucleus is simulated, and a good agreement with the anti-trapping current (ATC) model [Karma, Phys. Rev. Lett. 87 (2001) 115701] is obtained. By further studying the solute trapping effect during directional solidification, we find that the results give, with this model, a good thermodynamic consistence without solute trapping over two-order increment of the solidification speed and the interface thickness. Good agreement with the classical theory is obtained as well

    Audio - Mr. Whiteley recounts the story of delivering the message of the flood of 1904. He took seventeen hours by horse to travel from Perryvale to Edmonton. Billy Loutit took the same message by foot arriving in Edmonton about the same time. Mr. Whiteley discusses early settlers, farming, homesteading and businesses. He has many anecdotes about life and people living in Athabasca at the start of the twentieth century. He freighted for ten years with the Hudson's Bay Company and also discusses early farming prices and technology extensivelyInformative Interview of Mr. C.J.
