High-energy ball-milling is a process that mixes multiple raw powders with greater efficiency before their sintering process [6, 7]. It may alter the microstructure of the powder mixture. In the high-energy ball-milling process, powder particles are possibly broken and undergo significant plastic deformation [8–12].

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

Results of high-energy ball milling of Ti and Fe powder mixtures to obtain TiFe intermetallic compound are reported. Previously, we used various process control agents (PCAs) to solve a cold welding problem in a SPEX mill. In this work, we continue that investigation but without adding PCAs and also using a planetary ball mill.
