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].

These materials are organized in a „sandwich” structure with different reinforcements and welded by ultrasound.
They improve the bond between polymers of printing materials.
This composite can be used in the field of „Eco-nano-technologies and advanced materials” (new generations of environmentally friendly materials) such as aeronautical, but especially with applications in renewable energy, in entities aiming at the construction of blades for wind power plants, respectively the construction of propellers in industrial fans, the reinforced material being adaptable to extreme weather conditions.

In many practical cases, such extremely fast rates are not desired for the formation of structural materials.
Therefore, dilution of the reaction mixture with an inert material (usually product of the reaction) is needed.

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.
