THE ANNEALING STUDIES ON THE STRUCTURF AND PROPERTIES OF ELECTROLESS AMORPHeT TRANSITION METAL-METALLOID SYSTEM: Ni 10

Abstract

Amorphous metallic alloys, characterised by the absence of a long range atomic order, have emerged as an important class of materials of widespread scientific and industrial interest. These materials have unique magnetic, electrical transport, mechanical and other physical pro-perties as a direct consequence of their non—crystalline structure. There are two important classes of magnetic amor-phous alloys— the transition metal—metalloid system and rare earth transition metal system. The transition metal—metalloid amorphous alloys have been prepared by various techniques, like rapid quenching from the melt, sputtering, electrodeposition and electroless deposition. The transition metal—metalloid amorphous alloys prepared by a relatively simple technique like electroless deposition have not been investigated in detail. Also, the thermal stability of these alloys as revealed by annealing studies and the modes of crystallization may, to an extent, depend on the tech-nique used in their preparation.....
