In grain-boundary strengthening, the grain boundaries act as pinning points impeding further dislocation propagation. Since the lattice structure of adjacent grains differs in orientation, it requires more energy for a dislocation to change directions and move into the adjacent grain. The grain boundary is also much more disordered than inside the grain, which also prevents the dislocations fro… kapura hospitality groupWebJun 18, 2024 · @article{osti_1374188, title = {Two modes of grain boundary pinning by coherent precipitates}, author = {Wang, Nan and Ji, Yanzhou and Wang, Yongbiao and Wen, Youhai and Chen, Long-Qing}, abstractNote = {Here, we propose a two-mechanism theory to estimate the pinning effect of coherent precipitates on grain-boundary (GB) … law of insolvency studocuWebThe particles also improve the high-temperature creep strength by pinning grain boundaries which restricts sliding.
