#10 Impact of the Nanoscale on the Hall Petch Relationship | Nanotechnology, Science & Applications

Welcome to 'Nanotechnology, Science and Applications' course ! This video examines how the Hall Petch relationship changes at the nanoscale.It explores the mechanisms of grain boundary strengthening and how they are affected by grain size reduction.The video introduces the concept of the inverse Hall Petch effect, where strength decreases below a critical grain size. NPTEL Courses permit certifications that can be used for Course Credits in Indian Universities as per the UGC and AICTE notifications.
