What Is CNC? CNC Machining is a manufacturing process where computers run programs that control how the machines will manufacture parts.. These CNC Programs using CNC Software can control everything from the motions the machine makes to spindle speed, turning coolant on or off, and much more. The computer language used to program CNC Machines is called "G-Code".

The XRD results show that there are two major phases exist in bulk α-Fe(Si,Cr) solid-solution: the ordered phase (DO3) and the disordered phase (A2), and a DO3-to-A2 phase transition occurs in the milling process. After 80 h of milling, the grain size decreases from 50.1 to 33.7 nm, and the internal strain increases from 0.079% to 0.485%.

The mechanical milling process causes the refinement of Pr/sub 2/Fe/sub 14/B, alpha -Fe, and Pr-rich phases through a process of continuous fracture and cold welding. During heat treatment a new metastable phase and a layered Pr/sub 2/Fe/sub 14/B phase are formed at about 420 degrees C and 480 degrees C, respectively.

Surprisingly, the texture arising from the ball milling process can directly be related to the classical rolling texture of cold rolled Fe. In addition, full homogeneity can be achieved even on the nano-scale for this material as shown by APT, resulting in an extended miscibility region in comparison to the equilibrium phase diagram.

bcc Fe powder. The spectrum recorded after 32 h of milling reveals more advanced alloying. A significant decrease of the intensity of the bcc Fe sextet in favour of the intensity of the paramagnetic doublet was observed at this stage. The doublet seen in the centre of the Moss spectrum was attributed to the paramagnetic solid solution.
