The term "sub-material" is not widely recognized in chemistry, leading to confusion among participants. In the example of mixing coffee, sugar, and water, water acts as the solvent, while coffee and sugar are considered solutes. The discussion suggests that the solvent may be analogous to a substrate in other contexts, such as in microelectronics. Clarification on the term "sub-material" is needed, as it does not align with standard chemical terminology. Understanding the roles of solvents and solutes is essential for grasping the concept being discussed.

What is meant by the sub-material?

Such as if you mix three differential materials, for example, coffee + sugar + water, which one them is the sub-material?

Thank you

I shouldn't even be in this thread, because I know almost nothing of chemistry, but I have to ask what you mean by "sub-material". I've never heard that term before.
In the case that you cited, the water would be the solvent and the other two solutes. I guess that the solvent would be the liquid equivalent of a "substrate" such as the silicon in a microchip, but I somehow suspect that you refer to something else entirely.
 

Thread 'Need to anneal 5052 aluminum'

I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
