A Review of Accelerated Test Models
Nowadays nanopowders of metals, alloys, intermetallides, and their chemical compounds are produced by different ways. One of the problems suppressing promotion of nanopowders to the industry is the absence of reliable and objective methods for their testing.
Methods for The Testing of Nanopowder
Experimental results show that it is necessary to vacuumize the nanopowders (not more than 10 Pa) and to treat it with helium at 7090°C in order to remove adsorbed gases and loosely coupled chemical compounds.
Methods for The Testing of Nanopowder
