1. I don't understand pretty much the whole forging paragraph your explanation of the piston is an example you say a forged piston it's stronger because if the material it's made with. If you take a piece of tin foil touch it with a torch it's got a big hole in it now take the entire roll put it in a gynormous press squish it to the same thickness it was as just one sheet and touch it with a torch and it takes more heat to destroy it, the object now has more mass for a given size
2. I also do not understand how billet is stronger what happens if you take drawn or extruded rounds it's same material just compacted grain and you still put in your cnc lathe and make your part as I read on the net our aerospace industry makes tons of parts from billet but they start with forged material and I also looked up forging and learned that forging can be as simple as a billet part being put Into service and though normal operation it naturally work hardens or forges itself
Again not picking just want to understand
Happy turkey day everyone
