“…Some spread from the <110> texture towards <113> is also seen in Fig.3. This texture is similar to those obtained after heavy compression of pure fcc metals with medium and high SFE values [14,15].…”

Average microstructural parameters and the extent of microstructural heterogeneity in nickel deformed at a high strain rate have been characterized quantitatively and compared to those after compression at a quasi-static strain rate. The microstructure in the high strain rate sample was found to be more refined and less heterogeneous than that in the sample compressed at a low strain rate. The greater refinement in the former sample was achieved due to subdivision by a high frequency of finely-spaced low-angle boundaries.

“…5 both (a) without and (b,c) with dynamic testing. Thus, the alloy has a random texture after solution treatment but it develops a deformation texture after dynamic testing at (b) 298 and (c) 673 K. This texture is typical of fcc metals with high stacking fault energies after compression testing and it is characterized by a fibre-type texture where the compression axis is the fibre axis [69,70]. As is evident from Figs.…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. AbstractExperiments were conducted to evaluate the flow properties of an Al-3Mg-0.2Sc alloy both without and with processing using equal-channel angular pressing (ECAP). The initial grain size was ~300 m and this was reduced to ~250 nm by ECAP and then increased to ~600 nm by annealing at 673 K for 10 min. Tests were conducted to determine the mechanical properties over seven orders of magnitude of strain rate from ~10 -4 to ~10 3 s -1 .The results confirm the validity of the Hall-Petch relationship in the material processed by ECAP. Shear banding occurred in the coarse-grained material during dynamic testing but in the ECAP-processed alloy there was only minor grain coarsening. There was evidence for dynamic strain ageing in both the coarse and the ultrafine-grained (UFG) alloy with a transition in flow mechanism at high temperatures from dislocation climb in the coarsegrained material to superplasticity in the UFG alloy.

“…For body-centered cubic (bcc) iron-based systems, the deformation texture after compression is dominated by h100i and h111i fiber texture components aligned with the compression axis (CA), and it is generally found that the h100i component weakens during recrystallization, whereas the h111i fiber texture strengthens significantly. [1][2][3][4] In a previous study [3] on a modified ferritic/martensitic 9Cr-1Mo steel where samples were deformed to a strain of 0.5 either by quasistatic compression (QSC) or by dynamic plastic deformation (DPD), [5,6] it has been found that DPD resulted in a stronger h111i + h100i fiber texture and in faster recrystallization than QSC. The faster recrystallization was attributed to a finer boundary spacing and, therefore, a higher energy stored during DPD as compared to QSC.…”

The evolution of the microstructure and texture during annealing of a modified ferritic/martensitic 9Cr-1Mo steel compressed by dynamic plastic deformation (DPD) to a strain of 2.3 has been investigated using transmission electron microscopy and electron backscatter diffraction. It is found that the duplex h111i + h100i fiber texture formed by DPD is transformed during annealing to a dominant h111i fiber texture, and that crystallites of the h111i component have an advantage during both nucleation and growth. Detailed characterization of the microstructural morphology, and estimation of the stored energies in h111i-and h100i-oriented regions in deformed and annealed samples, as well as investigations of the growth of recrystallizing grains, are used to analyze the annealing behavior. It is concluded that recrystallization in the given material occurs by a combination of oriented nucleation and oriented growth.
