AbstractWe present a direct visualization of spontaneous gas dissolution in Al-7.7 mass% Ca eutectic alloy melt during superheating using high-brilliance synchrotron X-ray imaging. A bubble-involving gas dissolution process was observed, which can be understood within the framework of adsorption-diffusion-dissolution mechanism. The heterogenous nucleation and combined effect of hydrogen diffusivity and solubility results in the growth of individual bubbles in a stochastic way with Gaussian distribution. This also applies to the behavior of group bubbles in early stage, while which in final stage can be treated as reverse Ostwald ripening dominated by Lifshitz-Slyozov-Wagner diffusion mechanism when pure diffusive condition is satisfied.
