That is, the thermite reaction between Al and [Fe.sub.2][O.sub.3] was not triggered under quasi-static compression.
The melting/exothermic reaction starts from these interfaces between Al and iron oxide interface and the thermite reaction progresses regarding the following stoichiometric equation:
The reaction is known as a thermite reaction, and is used to weld metal together or create ceramics.
It is also possible that the presence of the aluminum with burning magnesium created a thermite reaction that cut through some steel beams in certain areas.
