摘要

An accelerated method for growing oxide whiskers on aluminium-containing stainless steel foil comprises heating the foil in air at an initial temperature suitably less than 960oC, preferably between 900oC and 950oC, to initiate whisker growth and thereafter increasing the temperature to above 960oC, preferably between 960oC and 990oC, 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.
