Thank you for making this video, I got a crazy out of the blue notion that I should learn about metal forging. You made things very clear and explained it so I can understand what you meant without blacksmithing jargon. I am about to watch part 2.

Another question - are dendrites smaller than grains, i.e. grains are formed of dendrites? I saw illustrations of grains with dislocations and the grains seemed uniform in their atomic arrangement, with the arrangement only changing direction at grain boundaries. This does not seem possible to me if grains are composed of dendritic structures. So dendrites are then larger than the grains, and formed of many grains?

@TheMudfly80 4 жыл бұрын

I thought cold worked materials that have smaller grains are more brittle, I did not think that larger grained materials were more brittle like in 5:20

Interesting how the grains at 4:30 resemble megalithic stone structures that fit together.

Forging is very quite sight to see. I saw some other video video. The red hot metal was punched and pressed. It is quite a sight.

So what the difference between forging method and heat treatment methods and why heat treatment method still been used widely? Why the not skip it for forging method

@infinitymfg5397 5 жыл бұрын

Hi Al Malki Heat treating is a process to change the properties of metal, makes it harder, tougher, etc. Forging is primarily meant to change forms and shape. It just happens to take place at the recrystallization stage.

Im pretty sure you are wrong about forging taking the material to a temperture of the 'mushy zone' forging can occur at like half the melting point.

@infinitymfg5397 3 жыл бұрын

Hi Ed, the mushy zone or recrystallization stage of a metal is below the melting point, as a matter of fact, its a broad range that between the metal in a solid state and when it is fully liquid. And you're correct it's possible for this to be 1/2 of the melting point. I will provide you with a link for more information. www.forgemag.com/articles/83794-forging-materials-plain-carbon-and-low-alloy-steels#:~:text=While%20typical%20hot%20forging%20temperatures%20are%20between%202150%C2%B0F,will%20significantly%20reduce%20mechanical%20properties%20and%20forging%20ductility.

"While typical hot forging temperatures are between 2150°F and 2375°F - well below the melting temperature of more than 2500°F - deformation (adiabatic) heating results in local heating. "

@edwardalborghetti4315 3 жыл бұрын

@@infinitymfg5397 I understanding forging can take place at a range of temperatures. The purpose of a successfully forged component is for there to NOT be any liquid and therefore NOT any mushy zone on deformation. Also your point about the purpose of forging is to reach recrystallisation is not the main point, to reshape and strengthen the material is the main goal. Also: after recrystallisation the 'grain flow' in not aligned. The structure should be equixed and uniform if rolled at an appropriate temperature.

So why are smaller grains less brittle?

@guanhan898 3 жыл бұрын

I thought smaller grains are much more brittle because it is better at resisting movement. So at 5:11 it should be less brittle?

@TheMudfly80 4 жыл бұрын

Is the recrystallisation temp really above the solidus line and in the 'mushy' state? I read it was below the melting point in pure solids. It seems strange / dangerous to hot roll a material/alloy that's partly liquid.

@infinitymfg5397 4 жыл бұрын

In an alloy a metal recrystallizes above the solidus but below the liquidus. The metal hasn't reached a molten state at this point so when it is rolled the crystals form with the new shape. It is dangerous simply due to the fact that you're forging metal but there is no concern of a 'splash' since it is not molten.

@@infinitymfg5397 thanks I always thought that above the solidus line it would still fill any container you put it into like a liquid, I visualised it more as a bowl of cornflakes
