Haynes 25 alloy (also known as L-605 alloy) is cobalt based super alloy which has widely applications such as aerospace industry, turbine and furnace parts, power generators and heat exchangers and petroleum refining components due to its excellent characteristics. However, the workability of this alloy is more difficult compared to normal steels or even stainless. In present work, an experimen...

118 LLE Review, Volume 94 Introduction High-quality targets must be provided to achieve successful results from OMEGA cryogenic experiments.1 One type of target is a thin-walled polymer capsule with a fuel layer of solid deuterium (D2) or deuterium/tritium (DT) ice, approximately 100 mm thick, uniformly distributed on the inner wall of the capsule.2 To create the fuel layer, the capsule is plac...

A simple cryogenic device is described. This device is capable of cooling neural tissue in contact with the probe and maintaining the tissue at the desired temperature for extended periods of time. The cold probe can thereby reversibly block neural transmission through small portions of the spinal cord white matter. Interruption of axonal transmission is achieved by placing the tip of the devic...

The effects of deep rolling parameters, particularly, work speed and cooling conditions (dry cryogenic) on the surface integrity AISI 304L machined samples their further impact uniform localized corrosion behavior in chloride environment were experimentally investigated this work. electrochemical rolled was assessed using cyclic potentiodynamic polarization tests synthetic seawater. It found th...

The superconducting magnet system of the ATLAS detector will consist of a central solenoid, two end-cap toroids and the barrel toroid made of eight coils (BT) symmetrically placed around the central axis of the detector. All these magnets will be individually tested in an experimental area prior to their final installation in the underground cavern of the LHC collider. A dedicated cryogenic tes...

An alternative, subcritical-temperature austenitic nitriding process is evaluated in this paper with the purpose of accelerating the treatment cycle, optimizing the hardness gradient in nitrided layers and seeking improved process control. Comparing to the conventional nitriding processed at ferritic temperature and followed by slow cooling, the alternative process includes nitriding at elevate...

This review discusses the progress and ongoing efforts in optical refrigeration. Optical refrigeration is a process in which phonons are removed from a solid by anti-Stokes fluorescence. The review first summarizes the history of optical refrigeration, noting the success in cooling rare-earth-doped solids to cryogenic temperatures. It then examines in detail a four-level model of rare-earth-bas...

The purposes of this study were to evaluate and compare the ability of wet ice (WI), dry ice (DI), and cryogenic packs (CGPs) to reduce and maintain the reduction of skin temperature directly under the cooling agent and to determine whether the cooling effect on skin extended beyond the surface area in contact with the cooling agent. Ten female volunteers participated in the study, and each of ...
