I hope your home freezers are colder than +32F because the colder it is the longer you can keep food .It should be no warmer than +10F and preferably -10F. However even if it's -10F the influence on heat treating will be minor......AwP, you're confusing terms .Austempering gives you bainite. Marquenching or martempering gives you martensite.Typically the retained austenite will decompose to martensite at typical tempering temperatures [ below Ms ] I wouldn' try to produce duplex structures.... Also I should mention here that excessive austenitizing temperature will produce excessive retained austenite .
