This study addresses the longstanding absence of a comprehensive phylogenetic backbone for apple tribe Maleae, deficiency attributed to limited taxon and marker sampling. We conducted an extensive sampling, incorporating 563 plastomes from diverse range 370 species encompassing 26 presently recognized genera. Employing inference methods, including RAxML IQ-TREE2 Maximum Likelihood (ML) analyses, we established robust framework Maleae tribe. Our phylogenomic investigations provided compelling...
Oxidation behavior of the uncoated base, Ni–Al coated and Re–Cr-Ni plus single-crystal (SC) Ni-based TMS-82+ superalloy is studied under cyclic air at 900 °C for 200 h to assess oxidation resistance. Regardless coating processing, effective in improving resistance due formation a continuous α-Al2O3 layer scale. For base superalloy, mass-gain curves are fitted by subparabolic relationship, complex oxide products including predominately NiO, some CrTaO4, α-Al2O3, Cr2O3, minor spinels (Ni,...
Abstract The characteristics of the deformation bands (DBs), formed in cyclically deformed copper single crystals with various orientations, were summarized systematically. formation mechanism DBs was also explored. It shown that appearance seems to be a general phenomenon slip especially double- or multiple-slip for which critical plastic strain amplitude needed is rather low (about 10−3). DB denoted by DBI develops roughly along primary plane {111}, and habit DBII close conventional kink...
Abstract The features of the deformation bands (DBs) in copper single crystals under cyclic straining were surveyed. A simple model was proposed to account for formation DBs. In this model, both crystal rotation and dislocation density variation induced by considered. gradual lattice caused tension compression irreversibility is main driving force drastic release mobile dislocations resisted primary slip direct trigger From analysis, one may understand why DBs easier with double-...
Ultrafine‐grained copper samples produced by equal channel angular pressing were cyclically deformed at different temperatures under a constant stress amplitude of 200 MPa, and the corresponding microstructures investigated transmission electron microscope. The increase in temperature during cycling facilitated grain coarsening led further to general change from dislocation walls well‐defined cells as well occurrence few annealing twins final fatigued UFG above recrystallization.
The fatigue behavior of ultrafine-grained copper produced by equal channel angular (ECA) pressing was investigated at temperatures between room temperature and 573 K under a constant stress amplitude 200 MPa. Cyclic softening found to be much more evident the corresponding life decreases rapidly as increases. This phenomenon considered being result grain coarsening microstructural changes in coarsened grains associated with testing temperature. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
Abstract The internal and external stresses around a triple junction of copper have been analysed by disclination model three-dimensional anisotropic finiteelement method respectively. results indicate that the stress depends on whether line is an I-line or U-line. At elastic strain energy concentrations caused depend both orientations component grains loading directions. For direction parallel to line, concentration usually large. perpendicular complex; in some cases, dispersion can occur...
The surface deformation features in ultrafine-grained copper produced by equal channel angular (ECA) pressing, which was cyclically deformed at temperatures between room temperature and 573 K under a constant stress amplitude of 200 MPa, were investigated. It found that the damage behaviour are strongly dependent upon testing temperature. For examples, large-scale shear bands (SBs) formed temperature, whereas finer discontinuous SBs, instead to become dominant feature with increasing (below...
