METALLURGICAL CHANGES IN STEELS DUE TO CRYOGENIC PROCESSING & ITS APPLICATIONS

Metallurgical changes in steels due to cryogenic
processing & its applications

Abstract:
Cryogenic processing is a supplementary process to conventional heat treatment process in steels. It is an inexpensive one time permanent treatment affecting the entire section of the component unlike coatings. Though the benefits have been reported widely, there are issues debated upon, in respect of the treatment parameters, extent of benefits ex ....etc

INTRODUCTION
Solid freeform fabrication (SFF) encompasses a class of processes that can be used to design and construct parts using a layer-additive approach. SFF processes are an outgrowth of rapid prototyping processes such as stereolithography for plastics and welding repair techniques employing laser, electron beam, or arc welding for repairing metal seal knife edges, turbine blade tips, or tooling dies. Current development efforts are expanding these repair techniques and applying principles from ....etc
