Inventor(s):
S.Ray, S. Ghanaraja and Sumeer K. Nath  
Applicant:
Indian Institute of Technology (IIT) Roorkee 
Application type:
Applied - 2010-05-19 
Application Number:

Abstract:
The present invention is a novel and unique method of manufacturing aluminum metal matrix, nanocomosites reinforced with nanoscale aluminum oxide particles. It is an object of the present invention to create a novel, unique, and simplified process for producing aluminum metal matrix nanocomposites reinforced with nanoscale aluminum oxide particles having a controlled volume fraction and uniform distribution in the aluminum matrix. Another object of the present invention is to provide such a technique that utilizes the Al2O3 surface layers existing on all aluminum particles as the ceramic reinforcement Yet another object of the present invention is to provide a method for producing Al-MMNC having unalloyed aluminum or an aluminum alloy as the metal matrix and having fine grain sizes. Still another object of the present invention is to provide a method for producing an Al-MMNC that is heat-treatable, formable, easily machined and weldable. 

 
THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
