title: [The fluidity of alloys in high temperature. (Part 1) Testing apparatus of fluidity in high temperature (author's transl)].
abstract: The method and apparatus for testing the fluidity of molten alloy in the mold of high temperature as far as about 650 degrees C were designed and the fluidity of pure Ag and Ag-Cu alloy were measured. The results were summarized as follows. (1) The flow length (y mm) of pure Ag increased as the degree of superheat (B degree C) watch with casting temperature minus melting point and the temperature of mold (A degree C) increased. Estimating the formula for the flow length y, it was found that y was represented by the sum of the first order formula of A and B. (2) The flow length of Ag-Cu alloy took large value when the mold with heated up to 650 degrees C. Estimating the formula for the flow length y, it was found that y was represented by the sum of the third order formula of A and the first order formula of B and the formula of the product of A and B.
