2. Austempering - Wikipedia

   en.wikipedia.org/wiki/Austempering

   In steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austenite known as ausferrite. It is primarily used to improve mechanical properties or reduce / eliminate distortion. Austempering is defined by both the process and the resultant microstructure.

3. Pearlite - Wikipedia

   en.wikipedia.org/wiki/Pearlite

   During slow cooling of an iron-carbon alloy, pearlite forms by a eutectoid reaction as austenite cools below 723 °C (1,333 °F) (the eutectoid temperature). Pearlite is a microstructure occurring in many common grades of steels.

4. Ferrite core - Wikipedia

   en.wikipedia.org/wiki/Ferrite_core

   Several ferrite cores. In electronics, a ferrite core is a type of magnetic core made of ferrite on which the windings of electric transformers and other wound components such as inductors are formed. It is used for its properties of high magnetic permeability coupled with low electrical conductivity (which helps prevent eddy currents).

5. Ferrite bead - Wikipedia

   en.wikipedia.org/wiki/Ferrite_bead

   A ferrite bead – also called a ferrite block, ferrite core, ferrite ring, EMI filter, or ferrite choke [1] [2] – is a type of choke that suppresses high-frequency electronic noise in electronic circuits. Ferrite beads employ high-frequency current dissipation in a ferrite ceramic to build high-frequency noise suppression devices.
