Description/Abstract | Recent work on a new glass-ceramic/alloy for pyrotechnic components is discussed. A newly developed family of austenitic stainless steels has been hermetically sealed to a widely used lithia-alumina-silica (LAS) glass-ceramic. These alloys, originally developed for high oxidation resistance, contain 4-5 wt% Al. The presence of Al offers several advantages from a glass or glass/ceramic sealing point of view: presence of a tenacious, stable oxide (Al{sub 2}O{sub 3}) on the alloys` surface as well as the fact that they can be strengthened during sealing via precipitation of a secondary phase, NiAl. In addition these new alloys offer lower material and machining costs and improved weldability compared to the widely used Ni-base superalloys. |
