Process Control Agents In Ball Milling

Sep 01, 2013 We employed controlled ball-milling and sintering: the use of some specific process control agents (PCAs) for ball-milling and sintering in a specific atmosphere. The use of our PCAs was beneficial both for homogeneous mixing and for the formation of hard dispersoids. Hardened layers was formed at the surface of the present aluminum-CNT

In this study, amorphous Fe 0.7 Nb 0.1 Zr 0.1 Ti 0.1 alloy without metalloids was produced by mechanical alloying of pure mixture elements. Miedema's semi-empirical model was employed to predict the possibility of amorphous phase formation in proposed alloying system.

Machining deformation prediction of thin-walled workpieces

Jun 08, 2018 Five-axis flank milling is the main processing method for manufacturing aerospace thin-walled workpieces. The sidewalls of such workpieces are prone to deformation during the milling process because of their low rigidity, which severely affects machining accuracy. Based on this fact, this paper proposes a novel model to predict surface form errors caused by milling force. This study
