WebWhen embrittling metals are solid, embrittlement can still occur (by SMIE) but it is much less severe than LME, in that times to failure are much longer, the crack velocities are much slower, and the extent of crack growth is much less (Fig. 6)[5, 18, 19]. Web28 mrt. 2004 · This investigation showed that failure of the 6061 Al-alloy was due to corrosion attack by liquid metal embrittlement (LME). Mercury corroded and embrittled the 6061-T6 Al-alloy resulting in several crack initiations along the edges of several blades and inside the expander wheel holes. LME also caused a loss of toughness, which led to ...
