Diffusion mechanism in XSi2 and X5Si3 (X= Nb, Mo, V) phases Soma Prasada and Aloke Paulb Department of Materials Engineering, Indian Institute of Science, Bangalore – 560012, India asoma_p@platinum.materials.iisc.ernet.in, baloke@materials.iisc.ernet.in Keywords: Interdiffusion, Silicides, Defects Abstract.
Molybdenum silicides are used as Schottky contacts in microelectronics [1-3], interconnects in VLSI (very large scale integration) photo mask material for fabrication [4, 5] of VLSI and soft X-ray mirror [6-8].
Nb based silicides are promising materials and considered seriously for replacing the currently used Ni-superalloys [11-15].

The operation in a single machine tool is the very basic operation transforming materials from a blank to parts or joining parts into a subassembly.
In the production process, the flow is materials and the objective is to make a product or a component from raw materials.
Operations management uses bill of materials, while project management uses WBS (Work Breakdown Structure).
The bill of material is a hierarchical breakdown of the product.

In the solid state, the hard and soft segments tend to phase separation due to segmental incompatibility, this two phase structure give rise to the interesting and useful properties of these materials.
The PTMO and MDI are commerially raw materials used in polyurethane manufature.
Small-Angle X-ray Scattering The degree of phase separation (DPS) and degree of interfacial mixing for two-phase materials were measured by SAXS.
