Definitions
- the method of heat treating a metal article which is subject to objectionable surface deterioration from contact with air at elevated, heat-treating temperatures, and of inhibiting such deterioration which comprises enclosing the article in the air in a bag of a thin, flexible oxidizablemetal sheet open along one edge only, pressing the bag about the article to reduce the air content of the bag, closing said open edge of the bag and without including in the bag any separate oxygen-removing material, thereafter heat treating the article by subjecting the article and bag in an atmosphere deleterious to the surface of the article to a heat-treating elevated temperature without previously having exhausted the air from within the bag and so as to substantially inhibit said atmosphere at the heat treating temperature from reaching said article in its deleterious form, and While said bag contains air at atmospheric pressure, and thereafter removing the bag from the article.
