The laves phase embrittlement of ferritic stainless steel type aisi 441

The laves phase embrittlement of ferritic stainless steel type aisi 441

The effect of Laves phase (Fe2Nb) formation on the Charpy impact toughness of the ferritic stainless steel type AISI 441 was investigated. The steel exhibits good toughness after solution treatment at 850°C, but above and below this treatment temperature the impact toughness decreases sharply. With...
