    Here T 0 is the bulk melting temperature, T the melting point in a pore of radius R p, and k p a constant characteristic of each probe liquid. In NMR cryoporometry, the melting point temperature distribution is detected through the intensity variation of the 1 H resonance of the unfrozen component of the confined substance, and the pore size distribution is calculated by using equation (7) .

    High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods.
