[The fluidity of alloys in high temperature. (Part 2) The fluidity of 20% Au-Ag-Pd-Cu alloy (author's transl)].
The flow length of 20% Au-Ag-Pd-Cu alloy in the mold heated up to 650 degrees C was measured by the apparatus reported in the previous paper with partial improvement added. The results were summarized as follows. (1) The flow length of Au-Ag-Pd-Cu alloy containing 20% Au in the mold heated up to 650 degrees C increased as the content of Cu increased in the range of 10-20% Pd; however, in the range of more than 22% Pd, it decreased as the content of Pd increased. (2) The maximum flow length was obtained around the composition of 20 Au-40 Ag-15 Pd-25 Cu. On the other hand the minimum flow length was obtained around the composition of 20 Au-65 Ag-10 Pd-5 Cu. (3) There was no correlation between the flow length and both of the melting point and the melting range solidifying area.
