ABSTRACT:
An accelerated method for growing oxide whiskers on aluminum-containing stainless steel foil comprises heating the foil in air at an initial temperature suitably less than 960.degree. C., preferably between 900.degree. C. and 950.degree. C., to initiate whisker growth and thereafter increasing the temperature to above 960.degree. C., preferably between 960.degree. C. and 990.degree. C., to continue whisker growth at an accelerated rate and thereby reduce the time and processing expense required to grow mature whiskers of a desired size.
