Annealing with induction heating

[lilbubka]

what if someone took a steel gas tank or a tank of welding gas and put it through the coil.. awsome explosion =)

[Arjoonmoal]

wtf????? nothing happened so you described the color.changes

[TheOnedeadguy]

what would happen if you put a magnet in there? ._.

[lilbubka]

@TheOnedeadguy .. good question!!.. when the steel cools are the atoms of the steel alligned just like they were with the magnetic force acting on it.. does it change the magnetic properties of the steel once cooled.. i have always wondered about this.. p.s. im only 17 so i hope no engineer or smart guy decides attacks jumps me through the comments list for asking such a question.. lol jk.. but seriously. it happeens a lot lol

[abcas1990]

@lilbubka its an ac power source ( in the kilohertz range ) the magnetic field alternates direction i don't think the atoms would have enough time to allign .. i'm no material engineer either

[rebel1211888]

@TheOnedeadguy you can't explain that.

[joblessalex]

@Imaginarycupcake123 nothing, your finger isn't metal or magnetic.

[imaginarycupcake123]

what if u stuck your finger in there?

[Slic3R1]

@imaginarycupcake123 nothing would happen unless your finger was metal or you had a metal part in it

Pretty voice

@karlsruheprotest Annealing will in fact improve ductility, the residual stresses from work hardening are a part of what makes it harder, add to that all of the dislocations and you get a much harder material, annealing relieves theses stresses and decreases dislocation, and in doing so improves the ductility. If your using alloys tempering will lead to precipitate hardening if you've ever tried to bend tempered aluminum you believe me.

[dotShinoda]

Holy!

[Evaseven]

i do watch part lathe work, gota anneal steel and whatnot, why did i not know about this? We just stick with a oxygen/gas torch to anneal

[Rakamonk]

hammering, stretching is cold work. But cold work causes stresses and energy is stored in the dislocated atoms (or slip systems), making it rather brittle. Annealing enables the recrystallization of grains (atoms shift and dislocations do no longer exist) . This means that the material becomes again ductile!

[peckiledorf]

@Rakamonk good one dude!

[deathblooms8324]

I use to work in a Heat Treating Plant. We did Stress Relief and Annealing

[artgoat]

With copper, you actually get a softer anneal by quenching it (opposite from steel). Slowly cooling it makes it harder.

[RRMetals]

@artgoat This is the case for copper alloys, and the reason is because the other metals in the solution precipitate as the alloy is cooled slowly, if it were pure copper slow cooling would produce more ductility, however most copper that people work with is in alloy form. This process is usually referred to as precipitate hardening.

[artgoat]

@RRMetals Actually it has to do with the crystal size in the copper. Annealing temperatures above 400C, recrystallization occurs, breaking larger crystals (especially in forged copper where crystals are elongated) These crystals only occur in pure copper. It's the work hardening of drawing that give pure copper wires their tensile strength.

[Ambrellinduction]

Annealing is used in a wide variety of manufacturing processes. Annealing is a heat treatment in which a material is exposed to an elevated temperature for an extended time and then slowly cooled. Annealing heat treatments are largely characterized by induced microstructural changes which are ultimately responsible for altering the material's mechanical properties. The ultimate goal of this process is to reduce the hardness of the metal and improve its ductility.

@Ambrellinduction And bring down heavy towers without explosives.

[XCptCarnageX]

sweet but whats the point

[bykashka75]

agree, very stupid vid

[nonigs007]

Numb nuts! Are you serious!? You can anneal, braze, solder, etc..in seconds without even contacting the work piece. Other applications would include inductive heating of a furnace, welding, etc...

[XCptCarnageX]

dude u have no life stfu
