What is 'autofrettage' 🧑‍🔧

I'd want to talk about "What is 'autofrettage'" in this article. Let's take a look at what it is and then respond to some frequent inquiries.

So the fastest answer is…

A process for manufacturing gun barrels. Prestressing the metal increases the load at which its permanent deformation occurs.

Autofrettage alters a container’s inside surface by inducing permanent compression to the material’s inner layers — even in the absence of internal pressure.

The process artificially strains the material with stresses above the elastic limit, taking them just into the plastic region.

Let’s start by reviewing a few questions people ask:

Autofrettage

What is autofrettage...

Autofrettage is a metal fabrication technique in which a pressure vessel is subjected to enormous pressure, causing internal portions of the part to yield plastically, resulting in internal compressive residual stresses once the pressure is released. The goal of autofrettage is to increase the durability of the final product.

What is the difference between autofrettage and unsourced...

Unsourced material may be challenged and removed. Autofrettage is a metal cold forming technique in which a pressure vessel is subjected to enormous pressure, causing internal portions of the part to yield plastically, resulting in internal compressive residual stresses once the pressure is released.
