SHAPE MEMORY ALLOYS
Introduction
Shape memory alloys (SMA's) are metals, which exhibit two very unique properties, pseudo-elasticity, and the shape memory effect. Arne Olander first observed these unusual properties in 1938 (Oksuta and Wayman 1998), but not until the 1960's were any serious research advances made in the field of shape memory alloys. The most effective and widely used alloys include NiTi (Nickel - Titanium), CuZnAl, and CuAlNi.
The two unique properties described above are made possi ....etc

Particle reinforced MMC?s are now being produced commercially and in this paper the various processing techniques used for the production of aluminium composites and factors affecting their quality are overviewed. The various techniques like powder metallurgy, spray deposition, molten metal infiltration, molten metal mixing, liquid metallurgy, compo-casting technique etc. The factors affecting the uniform dispersion of the composites and the various properties of the metal matrix composites are also discussed. Aluminium alloy matrix particulate ....etc

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

ABSTRACT
Tar column recoiled E4509 in the phenol plant of HOCL found failed in service un like any other exchanger s in phenol manufacturing process .Each failure very high cost to HOCL in terms of production loss due to down time for maintence and due to the loss of therminol liquid to the process .the loss due to each failure found to be nearly RS 1.5 chore >the cost of tube bundle in SS-316 is ....etc

INTRODUCTION
Powder metallurgy is concerned with the production of metal powders and converting them to useful shapes. It is a material processing technique in which particulate material are consolidate to semi finished and finished products. Generally the emphasis is on the metallic material but the principal of the process apply with little modification to ceramic, polymers and a variety of composite materials composed of metallic and non metallic phases. Nowadays powder metallic techniques are increasingly used to ....etc
