Yes, it would anneal them.
I have told this before, but it comes to mind every time someone puts up a thread like this. The weirdest thing I saw in the wild was not something I saw, but rather something I smelled.
I was solo hiking Mokelumne Peak in Mokelumne Wilderness in the Sierras, in an area that sees very little human presence. About five miles from the trailhead (which was at the end of five miles of dirt road so narrow that brush was scraping both sides of my car, which was at the end of maybe 10 miles of gravel road), I came to a large deadfall with a lot of trees in a jumble.
I was suddenly hit by an overwhelming smell. The only thing I can compare it to would be if you took a hundred stinky dogs that hadn't had a bath in years, got them all damp, and put them in one cramped room. I could taste it in the air. I walked by the deadfall area, paying very close attention to it. After summiting Mokelumne Peak, I returned the same way. When I got to the deadfall, there was no trace of any odor.
