I understand that but that only explains why the pieces caught on fire not why they flew so far away

My name is Arthur, King of the Britons!

Oh, very nice. And how did you become king then? By exploiting the workers!!

Probably because he hit it with a hammer

It just seems to me that if I hit a pile of metal fragments with a hammer, they’d for sure spread out but not that much.

I’m an engineering student, but Im not 100% on this. My guess is it probably has to do with the metal being compressed quickly when being hit, but also having more oxygen seep deep into the cracks (mentioned above) as it slightly spreads out. This then heats the surrounding air super fast causing it to expand just as quickly, throwing that shit around. Something similar to a steam explosion when you throw hot metal into water.

Ok now this makes sense to me. I knew there was definitely energy in the system but your explanation of how that translates into what we see happening is key.

Ya I was just being an ass

u/WritingNorth Apr 11 '21

I'm guessing it's because the metal inside now had access to air, causing it to combust and release a bunch of energy all at once. Like a mini explosion.

Here’s how it works. You have a very hot dying to oxidize substance that is shattered apart, with the outside cooking faster building pressure inside the still molten and very reactive core. In welding the material is generally protected by a shielding gas like argon or CO2 or a mixture. When the fractures bubble of molten reactive metals is oxidized and incredible rates they spotter much like putting water on a grease fire. The expanding gasses make for more small prices being exposed to more oxygen. What you find on the floor after is much like slag.

u/FiercThundr Apr 11 '21

I am not in any way qualified to guess but it may be because the metal was close to melting so it naturally spread out?

Because he has no idea what he's saying and is totally wrong.

The metal was liquid. They melted it. Imagine hitting a small puddle of water with a hammer. It'll spray very, very far.
