Crystallographic misorientation
WebAug 5, 2024 · According to the previous crystallographic analysis based on the K-S relationship, misorientation angles around 2°–4° and 7°–8° correspond to the lath and sub-block boundaries, respectively. 15, 16, 17, 18 Given this relevance, we can conclude that (1) the slip occurred within a single lath without cutting through any boundaries in the NB … WebThree ranges of misorientation angles of (I) important with regard to the distribution of crystallographic defects. The initial gap size between substrates is shown to affect the density of crystallographic defects in ranges (I) and (III) of misorientation, where dislocations and point defects exist at the interface.
