WebNov 18, 2024 · It is shown that the slope of Hall-Petch relationship of IF steel processed by HPT is larger than that processed by ECAP [4, 5]. In this study, IF steels with a wide grain size range were fabricated by ASR and subsequent annealing. Accordingly, the Hall-Petch relationship over a wide range of grain size was established and discussed. ...

Engineering science aspects of the Hall–Petch relation
WebNov 1, 1996 · The results provide no evidence to support the claims of a negative Hall-Petch slope when the average grain size is very small, but there is evidence of a decrease in the slope of the Hall-Petch plot at the very finest grain sizes (<150 nm); this is attributed to the increased participation of mobile extrinsic dislocations in the boundary ... WebJun 25, 2024 · Hall–Petch analysis revealed a high frictional stress (170MPa) and a high positive slope (0.13 MPa m) as compared to pure Al, which has a frictional stress (15–30MPa) and a slope (0.06–0.09 ... WebFeb 4, 2014 · Hall and Petch had established in the early 1950s a linear inverse square root of grain diameter dependence for yielding and cleavage of polycrystalline iron and steel materials, with ordinate intercept stress, σ 0, and slope value, k.
