Would have been interesting if you had a temperature probe on each ingot while they were in the press to see them heat up due to the friction during compression. See if some heat up more than others and how quickly.
Just use thermal camera geez. A temperature probe won't give an accurate reading because the metal constantly bending so good luck maintaining a good contact on that
The thing about brass and bronze (that looked like brass, btw) is that they're to copper what steel is to iron, with the atoms of the other, lighter element taking places in the structure and making it more rigid. Unlike steel, however, they're not hardened by heating and rapidly cooling (heating softens them reguardless of how they're cooled), but by work hardening through applied pressure. That's why it started with a soft deformation but became increasingly hard and brittle the longer pressure was applied.
@@Alltopicreader no it doesn't always became fragile... The properties of alloying elements outputs the alloyed property like brittle, malleable, thought, hard etc
If it was pure aluminum it'd probably look more like the tin in the end, it's real soft, you can scratch it with your fingernail. Pure is very expensive though so he probably had an aluminum alloy like 2024, 6061 or 7075.
@@snohoguerilla it's funny how Aluminium is expensive when it's more common than Iron in world-supplies.. Only it's properties makes it seen as more valuable than it is
Maybe someone has posted this already, but this yellowish-golden metal looks like brass (Copper and Zinc alloy) and not like bronze (Copper and Tin alloy)
My thought as well. Also, it seemed too brittle for bronze or brass. It could be an aluminum bronze. I wonder what type of bronze was used in this demo.
Bronze is tougher than iron. It's steel that is harder than bronze. There was a period in history where iron and bronze were both used extensively. High quality items would be made from bronze, but were expensive because Tin is only found in a few places in the world. Iron was far more common, but not quite as strong. Steel eventually replaced both as metallurgical science continued to advance, and steel product became consistent.
How a material responds under pressure depends on its atomic and crystal properties. Metals and alloys form crystals within the atomic lattice. Atomic properties set limits on what crystals can form. The properties of the crystals determine how ductile or brittle the metal is. Note that this is different from strength. A material may be generally weak or strong yet be more brittle or more ductile, depending on the crystal and environmental properties. This is why mechanisms made to be strong and not too ductile or brittle may still suddenly fail in very hot or cold situations. I would like to see this experiment repeated, but to include steel, an alloy of iron and carbon. Steel is stronger than iron but can be almost as ductile depending on how it is prepared. I would be curious to see separate comparisons of slow/air cooled bronze and fast/water cooled bronze made in otherwise the same way. Also, different bronzes prepared using different techniques but collection the same way. Also I would like to see different kinds of steel compared with iron, from different steel making techniques, and both slow and fast cooled. Fast cooled steel can form Marsenite (?spelling) which has a very brittle crystal lattice. Increasing ductility from Marsenite Steel involves phases of intense heating and careful cooling, an example of what I mean about environmental effects. Lastly I would like seeing crushed samples of Damascus steel, Katana steel, and modern tool steel. Thank you for the interesting video!
I meant, the bronze prepared with different techniques should be cooled down the same way. Different techniques can create different arrangements of crystals, and cooling in the same way prevents the environment being a factor in making the arrangements of crystals.
To me, this sample of yours does not look and behave like bronze, rather the color and brittleness indicate brass. Unless the video shows a bronze alloy with a high brass content.
Tungsten is a strong and very dense metal wich starts melting at a very high temperature of about 3,000 C°. I don’t think this hydraulic press would even get to deform tungsten, maybe by a centimeter but not more than that.
I'm almost sure that it is brass, and not bronze, as bronze is not that yellowish, and most of all, it is not that brittle if not heat treated. Brass instrad is very brittle
maybe some millionaire have a hydraulic press in their garage, even thought. it was atempted to those that have one not try. for the rest, just, you know.
Excelent demonstration, a very useful info, but if you add a device to show the heat parameters, may give a different perspective of investigation, never crazy, just a intuitive mind,
Did I told you only to imagine I am saying that after putting our hand under that what will happen . Understood!!!!!!!!??!??!!!!!???????!!!!!!😠😠😠😠😠😠😡😡😡
@@nandamonginis9966 and if you want to know what will happen after putting your hand under it you can go and try it out and yes, don't worry it's free😋😎😉
