  Have you ever used a waste oil burner in a 55 gall drum to melt cans put a hole in the bottom for the metal to pour out waste oil will melt it engine blocks in 5 minutes that are made of aluminum once it hits temp and that takes about 15 to 20 minutes I'd like to see someone melting barrels of cans in one I'm planing to build one I saw some that use fire bricks in the bottom and all the flag is caught by the fire bricks as the metal runs down around them I'm going to use an old 100 pound propane tank when I build my melting furnace it don't need insulation on the drum the burner is so hot

  I would guess that the orange tent of the ignots is from the orange sticker that was left on the bottom of one of the larger items he melted. It may have been the last item he put in. I was wondering why he didn't remove that orange sticker. I would remove any and all stickers, etc., for purity.

• 
  @backyardfoundryАй бұрын

  I am not a metallurgist, but my reasoning was 1.) the sticker will simply turn to carbon and would be some more slag 2.) or perhaps the carbon does alloy with the pewter but is a small enough amount I wasn't too concerned about it. Truthfully I am not 100% sure if it affects it or not.

  I would think of you out the gallium in the oil let it run the gallium will melt and mix with the oil leaving little gallium crystals all over the place when it cools. Then starting the engine cold might scratch the surfaces it is in contact with causing it to start reacting then leave the engine a few days and try to start it again.

I suggest "disco inferno" burn baby burn :) Anyway, I wonder if you could produce less slag or copper oxide during the remelting to obtain a better yield using various fluxes, nitrogen atmosphere furnace, alumina or zirconia (zircon) crucibles? Also, it would be fun to see various you create various alloya the copper with different metals and ratios (tin, zinc, magnesium, lead, gold, silver, antimony, germanium, bismuth). Then analyze the alloys in various states of crystallization (e.g annealed, work hardened, aged, tempered, solution treated, homogenized) then measure hardness, corrosion resistance (Gibbs equations), ductility, conductivity, ect. :)

  I'm pretty sure precipitation hardening is an other word for quench hardening. Rather, quenching precipitated the dissolved alloying elements to form martensite and other structures. I make knife blades from hardenable bronze. I forge the blades by hand, and temper them on the fire. It's important to note that on a lot of aluminum bronzes for exemple, the hardness doesn't really come from the quenching process (the bronze doesn't harden much after quench) but from the decomposition of the martensite, aka tempering / aging. However tempering aluminum bronze is still pretty unexplored, and even the latest research papers don't give very precise processes. So i personally had to practice and find for myself a method.

  I'm sorry, but precipitation is far from quenching, whereas the latter involves rapid cooling of heated metal. Precipitation is also known as age hardening, which involves slow cooling at room temp (i prefer warmer at 30 degrees celsius), which instead of annealing that happens to steel, in bronze metals it actually increases hardness and strength, and more superior to work hardening.

• 
  @jeanladoire4141Ай бұрын

  @@blueknyght923 thanks for the precision ! Precipitation hardening refers to the formation out of solution of some kind of hard structure (like martensite), and indeed i've seen that it was linked to heating up alloys, but as you said, steel doesn't need to be heated up, it rather needs to be cooled down. However i've seen that high alloyed steels do précipitation harden, around 500C, if you quench it first

  I'd guess the reason the gallium didn't eat the aluminum is the coating of soot. Even a thin layer of oxidation can protect against the reaction of galium from what I've seen in videos. Often people have to scratch up the surface to start the reaction if the metal isn't freshly cleaned beforehand.

  Explanation in easy terms for beginners: Steel hardening: Heating it will change the inner structure from one state to an other (cubed lettice structure will change inside) --> suddenly quenching it will cool the steel rapidly down without giving it´s inner structure enough time to change back again too it´s normal room temp state. This creating inner stress and making it harder. To release the stress yo ucan heat up the material again to about 500°C and let it cool down slowly which will change some but not all structure and release acess stress thus making the material still hard but not brittle. Aluminium hardening: Heating it will relax the material and alloy components like copper can move freely (495°C-505°C with the help of a candle you can reach this temp without melting the part), all the alloy contents will be the same roughly everywhere within the metal --> quenching it will not change that, however the metal structure will now start to change at room temp. The alloys want to create small islands and will clump together and thus hardening the material You will be able to notice a difference already after minutes. It´s full strength will be reached in about 4 days. You can speed up the process by warming the part, simply put it in an oven at 100°C or so for a while. The colder the temp the less the atoms can move. In aircraft design the metal will be cooled down to below freezing ca. -20°C, to prevent it from hardening too much before it can be riveted.

  precipitation hardening isn't age hardening, they are both different steps in the actual hardening. Basically it's like steel, but the opposite. when you quench steel it hardens, and you heat it up to disperse the martensite and have a more souple and flexible structure, but in a lot of non ferrous metals, quenching won't really harden the metal (quenching is precipitation hardening btw, beacause the alloying elements are expelled from the solution and form the martensite), but then heating it back up decomposes the martensite, and oddly enough, it's the decomposed martensite that actually becomes harder and stronger.

As with steels, the nickel aluminium bronze once quenched can be tempered to improve ductility whilst still retaining high tensile strength and hardnes..." generally speaking Al does not do therefore it hardens by age hardening primarily.

I'm a bladesmith, and i forge blades from cual bronze. It doesn't make very hard blades, actually they are both softer than steel, and more brittle, beacause i'm pushing the temper to its hardest to try to get a few more rockwells from it (i'm at about 30 i'd say, tho i've never measured it accurately). However it does make beautiful golden/brown blades that don't rust. It also holds a shaving sharp edge half decently, but i only make table knives or low intensity use blades from it (mainly for the esthetics, not the performance of course). I'd use a san mai of martensitic stainless steel and a core of very high carbon steel for the edge for cooking knives with actually good performance. But don't underestimate non metals for blades, more humans have died under the blows of bronze blades than under steel or bullets. It will hold an edge, just not for that long, and it needs frequent honing on a stone.
