Behind the finished vase are the spinning tools used to shape the metal. Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. [1] Spinning can be performed by hand or by a CNC lathe.
For example, for the standard ferromagnetic Potts model in , a phase transition exists for all real values , [7] with the critical point at = (+). The phase transition is continuous (second order) for 1 ≤ q ≤ 4 {\displaystyle 1\leq q\leq 4} [ 8 ] and discontinuous (first order) for q > 4 {\displaystyle q>4} .
Melt spinning is a metal forming technique that is typically used to form thin ribbons of metal or alloys with a particular atomic structure. [ 1 ] Some important commercial applications of melt-spun metals include high-efficiency transformers ( Amorphous metal transformer ), sensory devices, telecommunications equipment, and power electronics.
The general mathematical formalism used to describe and solve the Heisenberg model and certain generalizations is developed in the article on the Potts model.; In the continuum limit the Heisenberg model (2) gives the following equation of motion

A simple model of spin-transfer torque for two anti-aligned layers. Current flowing out of the fixed layer is spin-polarized. When it reaches the free layer the majority spins relax into lower-energy states of opposite spin, applying a torque to the free layer in the process. A schematic diagram of a spin valve/magnetic tunnel junction.

After some time, graphite refractory in contact with aluminium will react to create aluminum carbides (harder and more detrimental inclusions). In aluminium alloy containing magnesium , the magnesium reacts with some refractories to create rather big and hard inclusions similar to spinels.
