Improved functional fatigue resistance of single crystalline NiTi micropillars with uniformly oriented Ti3Ni4 precipitates

Fei Xiao et al.

Summary: Superelasticity is a promising functional property of shape memory alloys, and one important issue to solve in order to utilize it is to achieve sufficient fatigue life during the mechanical cyclic phase transformation. This study successfully manufactured NiTi single crystalline micropillars with different crystalline orientations and Ti3Ni4 precipitates. The micropillar with the [20 2_ 9]B2 crystalline orientation showed stable superelasticity during cyclic compression, with minimal decay over 107 phase transformation cycles. By analyzing the effects of cyclic martensitic transformations, the study suggests that tailoring aligned precipitates and preferred crystal orientation can lead to fatigue resistant shape memory alloys.

High strength and high ductility achieved in a heterogeneous lamella-structured magnesium alloy

Tong Wang et al.

Summary: This research has achieved excellent strength-ductility synergy in magnesium alloys by introducing a heterogeneous lamella structure. Strengthening and enhanced ductility were achieved through the non-uniform distribution of hetero-deformation induced stress, grain-boundary disclinations, and intergranular slip transfers. This provides a new approach to address the strength-ductility trade-off dilemma in magnesium alloys.

Enhanced twinning-induced plasticity effect by novel {315}α/{332}β correlated deformation twins in a Ti-Nb alloy

Xianbing Zhang et al.

Summary: A new {315}(alpha '') type deformation twinning system was discovered in a full alpha '' Ti-23Nb alloy, in addition to the {130}< 310 >(alpha '') system. After annealing, it was found that the {315}(alpha '') and {130}(alpha '') deformation twins transform into {332}(beta) twins of the beta parent phase. The study concluded that the presence of these deformation twins enhances work-hardening and plasticity in the alloy.

Enhanced superplasticity achieved by disclination-dislocation reactions in a fine-grained low-alloyed magnesium system

Min Zha et al.

Summary: Superplastic forming is crucial for producing complex-shaped components in Mg-alloys, especially in high-alloyed systems. However, stabilizing small grains and facilitating grain boundary sliding in low-alloyed systems is challenging due to insufficient precipitates. Through a unique design strategy involving solute segregation, an Mg-1Zn-0.2Ca-0.2Zr-0.1Ag (wt.%) alloy achieved ~450% superplastic strain by absorbing intragranular dislocations through stress-driven grain boundary migration mediated by disclination-dislocation reactions. This study provides insights into the relationship between microstructural defects evolution and strain accommodation during superplastic deformation, shedding light on the nature of superplasticity mechanism.

Dual-interface model for twinning in the coupled crystal plasticity finite element-Phase field method

Hanxuan Mo et al.

Summary: In this study, a dual-interface model is proposed to simulate the migration of interfaces and plastic deformation in crystals. The model integrates a constrained-sharp interface in finite element method for deformation fields and a refined-diffuse interface in phase field method for domain evolution. By utilizing a multi-classifier neural network fitting, the dual-interface model effectively diminishes the mesh sensitivity and improves the accuracy of simulation.

Summary: This study presents an experimental and theoretical investigation on twin nucleation in HCP metals, specifically identifying the {11(2) over bar1} twin nuclei in HCP rhenium originating from a <c+a> dislocation. The analysis rationalizes the favorability of dislocation-based nucleation mechanism and offers insights into design strategies for enhancing the balance between strength and ductility in HCP alloys.

Prominent role of multi-scale microstructural heterogeneities on superplastic deformation of a high solid solution Al-7Mg alloy

Min Zha et al.

Summary: This paper focuses on the superplastic response of a high solid solution Al-7Mg alloy processed by equal-channel angular pressing (ECAP) under uniaxial tension. The study reveals that the evolution of microstructural heterogeneities can be regulated to favor superplastic deformation, achieving impressive elongation of approximately 523%. The high superplasticity is attributed to the cooperated mechanism of dislocation slip accommodated by continuous dynamic recrystallization (CDRX) and grain boundary sliding (GBS) during deformation.

Enhanced ductility of Mg?1Zn?0.2Zr alloy with dilute Ca addition achieved by activation of non-basal slip and twinning

Nan Xia et al.

Summary: In this study, a Mg?1Zn?0.2Zr (ZK10) alloy sheet was prepared by multi-pass hot rolling and annealing, with the addition of dilute Ca to tailor the basal texture and reduce plastic anisotropy. Microstructural characterizations showed improved ductility due to the occurrence of pyramidal c+a slip in the deformed alloys. This work may offer a new strategy for developing wrought Mg alloys with enhanced ductility.

Formation of {11(2)over-bar2} contraction twins in titanium through reversible martensitic phase transformation

Amir Hassan Zahiri et al.

Summary: This study reports the discovery of a non-conventional twinning mechanism in alpha-titanium through reversible alpha -> omega -> alpha martensitic phase transformations. It demonstrates the important role of the intermediate omega-phase in the twinning process, adding critical details to the existing mechanism of {11 (2) over bar2} twinning. The study also confirms strict orientation relations between the parent alpha-, intermediate omega-, and twin alpha-phases.
