A novel near-α Ti-5Al-2Zr-1V-1Sn-1Mo alloy with Twining Induce Plasticity (TWIP) and Transformation (TRIP) effects was designed. The excellent combination of yield strength Rp0.2 ∼834 MPa fracture toughness KIC ∼114 MPa·m0.5 is achieved by tailoring multi-scale α phase, that includes micron primary grains (αp), sub-micro lath in the βtrans matrix (αlath) nano-scale platelets (αs) βlamellae. high tensile mainly stems from solution strengthening αs precipitation strengthening. βlamellae can...
The plastic deformation modes of commercially pure titanium (CP-Ti) were studied using an in situ tensile test monitored by electron-backscatter-diffraction (EBSD) assisted slip trace analysis. strain was primarily accommodated prismatic slip, followed twins and pyramidal slip. transmission between two adjacent grains predicted the geometric compatibility factor m′, which influenced not only degree stress concentration but also activity dislocation systems. Stress mainly occurred at GBs with...
In existing simulations of the Almen intensity test, arc height is indirectly obtained by an equivalent method including a representative cell, few shots and loading. Most these methods cannot consider transverse deformation strip, complex stress state plastic hardening layer process parameters, resulting in deviation from actual test. This paper introduces improved experimentally validated discrete element model (DEM)-finite (FEM) to predict intensity. The improvement this mainly reflected...
The gradient nanostructured (GNS) layer forms beneath the surface of Zr-4 samples by mechanical grinding treatment (SMGT) process, which increases fatigue strength apparently due to synergistic effect and compressive residual stress. SMGTed are subjected annealing remove stress (A-SMGT) individual GNS can be clarified. results show that nanostructure in is stable after at 400 °C for 2 h but removed. Both A-SMGTed exhibit higher than coarse-grained (CG) alloy. fracture alloy indicates hard...
