cryogenics heat treatment pdf

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 f ....etc

INTRODUCTION
The science and technology of deep refrigeration processing occurring at temperature lower than about 150 k. is the field of cryogenics. The name cryogenics is evolved from Greek word Cryos meaning icy cold. Phenomena that occurs at cryogenic temperatures include liquefaction and solidification of ambient gases; loss of ductility and embrittlement of some structural materials such as carbon steel; increase in thermal conductivity to a maximum value, followed by further decrease in ....etc

CRYOGENICS AND ROCKET PROPULSIONS



INTRODUCTION

A rocket is a machine that develops thrust by the rapid expulsion of matter. The major components of a chemical rocket assembly are a rocket motor or engine, propellant consisting of fuel and an oxidizer, a frame to hold the components, control systems and a cargo such as a satellite. A rocket differs from other engines in that it carries its fuel and oxidizer internally, therefore it will burn in the vacuum of space as well as with ....etc

1. INTRODUCTION TO CRYOGENICS
Cryogenics is the study of how to get to low temperatures and of how materials behave when they get there. Besides the familiar temperature scales of Fahrenheit and Celsius (Centigrade), cryogenicists use other temperature scales, the Kelvin and Rankine temperature scale. Although the apparatus used for spacecraft is specialized, some of the general approaches are the same as used in everyday life. Cryogenics involves the study of low temperatures from about 100 Kelvin to a ....etc

Cryogenic engineering is a sub stream of mechanical engineering dealing with cryogenics, and related very low temperature processes such as air liquefaction, cryogenic engines (for rocket propulsion), cryosurgery. Generally, temperatures below the boiling point of Nitrogen (77 K) comes under the purview of cryogenic engineering. Cryogenics may be considered as the recent advancement in the field of refrigeration. Though there is no fixed demarcation as to where refrigeration ends and cryogenics begins even then for general reference temperature ....etc
