I'm sure glad I asked. I have stacks of books on metalworking, welding and metallurgy. Many of them have mentioned "molecules" when discussing metal. I'm writing a book on hand shaping metal and I wouldn't want to make the same mistake.

each atom on the corner is only counted as 1/8 Sorry -- I've never seen a solid states physics book, much less read one. :smile: I know very little about physics -- I'm just searching for a little info regarding a specific area of metallurgy. At first, I didn't understand what you meant...

I'm still a little confused about crystals and grains. Does a crystal become a grain as the metal solidifies? I'm also not clear on molecules. For instance with a body centered lattice you have nine atoms. One on each corner and one in the center of the body. So within that lattice -- what...

I read in an old metal working book that when a auto body panel is struck sharply with a hammer that for a microsecond or nanosecond there is a vibration or "shock waves" that allows the grains of metal to slip past one another and re-arrange slight. I am desperately looking for an explanation...
