(a) Strain rate sensitivity m for as-cast state as a function of Pd-content (left axis, open squares) and absolute value of reduced pair distribution function at the length scale of 3-atom connections G(\(\sqrt {8/3}\) r1) in the as-cast state as a function of Pd-content (right axis, open circles). A decrease in SRS with increase in Pd content, associated with more brittle behavior, is observed. More rigid 3-atom connections in the reduced pair distribution function are observed with increase in Pd content, which is also characteristic of relatively brittle behavior. (b) Scatter plot of mas-cast and G(\(\sqrt {8/3}\) r1)as-cast showing the correlation of decreasing strain-rate sensitivity with increasing fraction of 3-atom cluster connections.
