Self-quenching effect

WebMar 9, 2024 · The controversial phase, metastable austenite, is deliberately retained in advanced quenching and partitioning (Q&P) sheet steels. Superficially, the plasticity of Q&P steels is enhanced through the transformation induced plasticity (TRIP) effect to a large extent. However, the role of retained austenite on the crack resistance of Q&P sheet steels … WebA common variant of this process is triplet quenching, when the donor is initially in the T 1 state. The excited states of typical quenchers like I are usually too high in energy for e cient resonant excitation transfer from dyes that emit in the visible, however, there can still be directed electron transfer from one molecule to another.[1]
