Oh c'mon RT, now your just trying to stump me . . . well you're gonna have to try harder . . .
You’re talking about the relationship between material strength and crystallite (grain) size. Generally the material strength goes up as the grain size gets smaller. There is certainly Hall-Petch strengthening effect involved with the NanoTek Material and we are at it's limit.
A simple fallacy that should be addressed for clarity is that “nano” is some sort of product or process when in fact it is a simple measurement of size. The size is one billionth of a scale measurement. You could have a nano-inch which would be one billionth of an inch, a nano-foot which would be one billionth of a foot but the most common, and in our case, is a nanometer or one billionth of a meter. To give you an idea of the scale we are dealing with, the size of atoms are measured in nanometers. A normal metallic atom has an estimated radius of .140 nanometers; so a Nanometer is about 4 atoms across.
Nano works for Anderson in the sense that the nano-technology we are referring to in our product is that the grain size of our nano-metal is measured in nanometers (1 X 10^12 meters). The grain size in the nano-metal is between 5 and 10 nanometers. This means our grain size is between 20-40 atoms across. The grain size in heat-treated steels or hard aluminum alloys is 10,000 times larger than the grain size in the Nano-metal.
Due to the way that grains interface each other, this size is so small that the grains lose the meaning of being individual grains. However, it is important to still think of them as individual grains, as the collection of their grain boundaries is what gives the material its exceptional hardness.
