A cryogenic treatment is the process of treating workpieces at cryogenic temperatures (ie below -190 C) in order to eliminate residual stresses and improve the wear resistance of steels. In addition to seeking improved stress relief and stabilization or wear resistance, cryogenic treatment is also sought for its ability to improve corrosion resistance by precipitating micro-fine eta carbures, which can be measured before and after in one part using a quantimet.
The process has a wide range of applications from industrial tools to improving th ....etc

A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer, that is, its fuel or oxidizer (or both) are gases liquefied and stored at very low temperatures. Notably, these engines were one of the main factors of NASA's success in reaching the Moon by the Saturn V rocket.

During World War II, when powerful rocket engines were first considered by the German, American and Soviet engineers independently, all discovered that rocket engines need high mass flow rate of both oxidizer and fuel to generate a sufficient t ....etc

A cryogenic treatment is the process of treating workpieces to cryogenic temperatures (i.e. below 190 C ( 310 F)) in order to remove residual stresses and improve wear resistance on steels. In addition to seeking enhanced stress relief and stabilization, or wear resistance, cryogenic treatment is also sought for its ability to improve corrosion resistance by precipitating micro-fine eta carbides, which can be measured before and after in a part using a quantimet.

The process has a wide range of applications from industrial tooling to the ....etc

cryogenic treatment of brake rotors ppt

Cryogenic Treated Rotors

For drivers who need something even tougher than a standard StopTech Sport rotor, but are not ready for a big brake kit, StopTech offers cryogenically treated Cryo rotors. Cryogenic treatment is a one-time stress relief process that involves both cold and heat cycling of the brake rotor. Using a proprietary computer-controlled process over a 24-hour period, the cryo machine gradually cools the rotors down to -300 F, then gradually brings them up to over +300 F, and finall ....etc

Abstract
Shift registers featuring radiation-hardening-by-design (RHBD) techniques are realized in IBM 8HP SiGe BiCMOS technology. Both circuit and device-level RHBD techniques are employed to improve the overall SEU immunity of the shift registers. Circuit-level RHBD techniques include dual-interleaving and gated-feedback that achieve SEU mitigation through local latch-level redundancy and correction. In addition, register-level RHBD based on triple-module redundancy (TMR) versions of dual-interleaved and gated-feedback cell sh ....etc
