01/03/1996· The deformation structures of copper powder induced by ball milling were studied in detail by using high resolution electron microscopy. It was found that copper powder after 20 h of milling shows the formation of shear bands and a number of mechanical twins. The observed twins belong to two types, i.e. multiple twins and high-order ones. It is suggested that Venables' model on mechanical twins in …
It has been observed that during repeated plastic deformation as in ball milling or cold rolling there is a concomitant refinement of grain size. Recently a new variation of the strategy has been developed which can yield nanocrystalline product structures I-31. By starting with a .

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. High-energy ball ...
