Incoherent twin boundary
WebJan 1, 2012 · It is worth noting that boundaries close to the CTB (<112> and <110> tilt boundaries with inclinations less than about 40° from the CTB) completely facet along the coherent twin plane, while... WebAccording to the research of Hongyuan Wen et al. , the coherent twin boundary (CTB) interface is not easier to nucleate and precipitate than incoherent twin boundary (ITB) and normal grain boundary (NGB) interfaces due to the difference in interface energy and diffusion rate in high-temperature service. 4.

WebThe carbides precipitated at incoherent twin boundary and Σ9 GB were identified as M 23 C 6. The bar-like carbides grow parallel to each other and into each side of grain nearby incoherent twin boundary, while only growth into one side nearby Σ9 GB is observed. The carbides precipitated at incoherent twin and Σ9 GBs contain twins.
