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.
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.
Typical components produced by metal spinning are lamp bases, reflectors, hollowware (pitchers, tankards, vases, candlesticks, etc.), pots, bans bowls and components for electrical equipment. [1] Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering art of designing products in such a ...
a solid solution mixes with others to form a new solution The phase diagram in the above diagram displays an alloy of two metals which forms a solid solution at all relative concentrations of the two species. In this case, the pure phase of each element is of the same crystal structure, and the similar properties of the two elements allow for ...
Joseph Bendik first noted the interesting motion of the spinning disk while working at Hughes Aircraft (Carlsbad Research Center) after spinning a heavy polishing chuck on his desk at lunch one day. The apparatus is a dramatic visualization of energy exchanges in three different, tightly coupled processes.
An example of an inverse spinel is Fe 3 O 4, if the Fe 2+ (A 2+) ions are d 6 high-spin and the Fe 3+ (B 3+) ions are d 5 high-spin. In addition, intermediate cases exist where the cation distribution can be described as (A 1− x B x )[A x ⁄ 2 B 1− x ⁄ 2 ] 2 O 4 , where parentheses () and brackets [] are used to denote tetrahedral and ...
Phase diagrams sketches demonstrating how Double and Triple Half-Heusler compositions are different from traditional alloy compositions. [7]Although traditionally thought to form at compositions XYZ and X 2 YZ, studies published after 2015 have discovered and reliably predicted Heusler compounds with atypical compositions such as XY 0.8 Z and X 1.5 YZ.
