HALL-PETCH RELATIONSHIP AND STRAIN RATE SENSITIVITY OF NANOCRYSTALLINE Mg - 5WT% Al ALLOY
This study investigated the grain size dependence of mechanical properties and deformation mechanisms of microcrystalline (mc) and nanocrystalline (nc: grain size below 100 nm) Mg-5wt% Al alloys. The Hall-Petch relationship was investigated by both instrumented indentation tests and compression tests. The test results from the indentation tests and compression tests match well with each other. ...

Hall-Petch Relationship: Use in Characterizing Properties of Aluminum and Aluminum Alloys*
The mechanical properties of aluminum are shown to be of special importance beginning from the early 20th century production of the material in single crystal and polycrystalline form. Experimental and theoretical researches of the time were concerned with particular influence of polycrystalline microstructure and the presence of crystal (grain) boundaries on both the material strength properti...
