At least classically, it's the process of compressing that yields the extreme temperatures, not the state of having been compressed. If you maintain the pressure, the hot compressed material will transfer thermal energy to its surroundings until it has cooled back down to room temperature, and it does not require further work to be done on the compressed material to keep it compressed.
