The effect of the amount of process control agent on the
ball mill. The effect of amount of stearic acid on production of Cu25W composite powder was evaluated. In order to achieve true alloying among powder particles, it is necessary to establish a balance between cold welding and fracturing. Hence, different types of process control agents (PCA) were used to reduce excessive cold welding.

Process Control Agent
A process control agent (PCA) is usually used in the process of mechanical alloying to avoid cold welding and bonding between the powder particles and the balls and the agglomeration of powder during milling, which is also noticeable for some alloy systems in the solid–liquid reaction ball milling process (Chen and Chen, 2006 ).
