The effect of milling time on the magnetic properties and phase formation of the MCE alloy was investigated in the present work. From powder XRD results, the ball milling technique does not change the Gd(5)Si(2)Ge(2)-type phase but broaden the corresponding Bragg reflection which implies the smaller crystalline size of milled alloys.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
