Uh, no. The instant the pressure is relieved, the metal turns hard again.
And pressure doesn't heat metal. Bending it can warm it up a little, but a pair of scissors cutting through an aluminum can doesn't heat up the
aluminum. What it does is create a highly focused pressure point allowing that point to become liquid. The area that is called "liquid" is
microscopic, and immediately returns to a solid metal once the pressure is reduced back below the threshold of phase change.
As for aluminum looking bright yellow and flowing like a liquid, it just doesn't happen. All metals have a physical property called emissivity. It
is a measurement of how much blackbody radiation they emit relative to temperature.
The color and behavior of that material seen flowing out of the WTC is entirely consistent with a metal consisting of at least 90% iron being heated
to 2,750 F. As you all know, no hydrocarbon fuel can reach this temperature in a 21% oxygen atmosphere.
Blackbody radiation theory (which is well understood in physics) dictates that if a material has this emission spectrum (bright yellow) its
temperature must be around 2750 F. This clearly presents a problem, because no common-sense answer is available to explain the existence of material
at this temperature.
To get something this hot, you must provide an exothermic oxidation-reduction reaction capable of those temperatures. In other words, you need a fuel
which can combine with oxygen and result in something very very hot. All burnable fuels that fall under the category of hydrocarbons (diesel fuel,
gas, jet fuel, wood, plastic, paper, etc) will only reach a maximum of 1800 F in a 21% O2 atmosphere. If you want it even hotter, you gotta up the
oxygen concentration and/or change what type of fuel you're burning.
If you take Iron III Oxide and let it combine with Aluminum, the oxygen on the Fe2O3 gets ripped off by the Al in a chemical reaction. In a sense,
the rust is "burning" the aluminum. This chemical reaction allows a maximum temperature of about 4,500 F. This is the chemical combination in
"Thermite". VERY hot.
If thermite was used in the WTC, then that would explain the source of oxidizer which would be needed to keep the hot spots hot weeks afterward.
If you take a candle and cover it, the flame goes out because it quickly uses up all the oxygen near it. At the bottom of the rubble pile in the WTC,
burning materials would have done the same thing. They would have used up all the oxygen, and gone out like a candle flame before too long. But
explaining how there could be so much heat down there so many weeks later is difficult, unless you add an oxygen source which can supply heat-creating
chemical reactions the oxidizer they need to keep going, producing heat.
