Abstract. The effects of milling atmosphere and mechanical alloying (MA) duration on the effective lattice parameter, crystallite size, lattice strain, and amorphization rate of the W-0.5 wt. Ti powders were investigated. W-0.5 wt. Ti powders were mechanically alloyed (MA'd) for 10 h and 20 h in a high energy ball mill. Moreover, morphology of the powders for …
Up Milling: Down Milling: 1. This machine is also called as conventional milling. This is called a climb down milling. 2. The cutting forces act upward. The cutting forces act downward. 3. Mostly used for rough cutting operations. This is used for finishing operations. 4. Due to the more tool wear rate, the durability of the tool is less.
One of the more commonly used milling techniques is known as mechanical milling, which generally requires a high-powered motor rotating some type of milling surface. Mechanical milling aims to reduce the particle sizes of material by physically breaking the structure of a material by overcoming the materials own interior bonding forces.
