Material Selection - Muzzle Blast
Material Selection - Muzzle Blast
(OP)
I am designing a type of muzzle break for small arms. One part of the brake will be directly impinged upon by the hot, erosive muzzle blast after the projectile has left the barrel.
I am looking for material suggestions. I am considering Inconel but was wondering if there might be some other, easier to machine material options.
TIA

Some of these rifles (from the 50's) were very well used in their country of origin (barrels shot out). The brakes had no discernable wear even after 40,000+ rounds.

TO clarify this is not a traditional pass thru brake but one that is directly impinged upon by the gases and that is very close to the muzzle.

Will this be tube-over-tube or machined from bar with drilled ports? How important are mechaical properties? Off hand I would suggest that you consider a duplex stainless. It will be strong and corrosion resistant.

Corrosion, every where, all the time.
Manage it or it will manage you.

There really is very little stress on the cone so mechanical properties are not that important.
I thought of a ceramic but it might be expensive to form something this size.
What type of duplex stainless were you thinking about?

The Haynes website is what I was looking for....thanks.
It looks like I can make the entry nozzle of the cone from one of their alloys and the rest from a cheaper stainless steel. Just need to be able to weld the two together.

What does the Barrett .50 use? I would assume that arrangement would work anywhere since (as far as I can tell from the website) they have a large amount of impingement on their brake.
As far as the insert - we use carbide in extremely abrasive/erosive gas flows. It can be cast to a reasonably accurate dims (+/-0.010).

The Barrett brake is an investment casting, material unknown. This brake is a little different as the 'cone' has a hole not much bigger than projectile diameter and it is very close to the muzzle....closer than the Barrett sits.....
