The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The analysis predicts that V_abs follows a trend similar to that of the miscibility gap, first increasing and then decreasing with Ag concentration. Predicted values of V_abs are in good quantitative agreement with PF simulations over the entire hypoeutectic concentration range and with experiments for three concentrated alloys.

C2weakest assumption

The non-equilibrium, velocity-dependent phase diagram extracted from the phase-field model accurately represents the real thermodynamic and kinetic behavior of the Al-Ag system at the high velocities of interest.

C3one line summary

Absolute stability velocity in hypoeutectic Al-Ag alloys first rises then falls with Ag concentration, allowing microsegregation-free planar fronts at velocities below 1 m/s for concentrated compositions.
