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.

In this study, two methods, i.e. high energy ball-milling and supercritical carbon dioxide impregnation (scCO 2) are compared, with the aim to predict their suitability for the vitrification of TD. The influence of the amount of SL and the kind of co-processing method on TD thermal properties is analyzed.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
