Summary: In this study, Ti-20Zr-(8-12)Nb-3Sn shape memory alloys were fabricated and their phase constitutions, texture characteristics and superelastic behaviors were investigated. It was found that the texture characteristics of the alloys can be tuned by varying Nb content, and the presence of Nb enhances the stability of the beta phase. The Ti-20Zr-(11, 12)Nb-3Sn specimens exhibited superior superelasticity, and the simultaneous presence of beneficial texture and superelasticity in the Ti-20Zr-11Nb-3Sn specimen is advantageous for biomedical applications.

Summary: Thanks to its unique superelastic response, Nitinol has become the preferred material in many critical applications, especially in the medical implant field. However, the reversible phase transformation that gives rise to its exceptional behavior also makes its mechanical characterization complex, hindering the assumptions underlying common uniaxial tensile testing. This study analyzes the spurious effects introduced by the unconventional material behavior during uniaxial tensile testing using digital image correlation (DIC), and proposes a more accurate and systematic testing approach.

Summary: This experimental study examines the use of pre-stretched pseudoelastic NiTi shape memory alloy wires in a new energy dissipation damper. The device demonstrates self-centering ability and good damping properties due to the pseudoelastic effect and structural parameters. Experimental tests with a prototype comprising of four 1.5 mm diameter pseudoelastic NiTi SMA wires confirm these desirable features. The results indicate that the proposed pseudoelastic SMA damper can effectively be used in structures subjected to cyclic loading in terms of post-yield strength, energy dissipation, and re-centering capability.

Summary: This study achieves multimodal locomotion of soft robots using highly compact and dynamic bistable soft actuators. These actuators can swiftly transform between two oppositely curved states and generate a force of 0.3 N. The consistency and robustness of the actuator response are experimentally validated.

Summary: In this study, an excellent two-way shape memory effect (TWSME) with large magnitude and small cyclic degradation of NiTi wires is achieved by combining martensite deformation and nanocrystallization. The wires exhibit a maximum TWSME strain of 7.37% after being pre-deformed to 11% and maintain a stable strain of 6.88% after 20 cycles. The excellent TWSME is attributed to the dislocation structures induced by martensite deformation and the nanocrystalline strengthened matrix.

Summary: Isothermal compression tests, EBSD observations, and quantitative analysis were conducted to investigate the effect of process parameters on microstructure variables during isothermal compression of NiTi shape memory alloy. The results showed that dynamic recovery is the dominant softening mechanism at lower strains, while dynamic recrystallization plays a significant role in softening the alloy at higher strains, leading to a steady state of flow behavior. Additionally, the occurrence of dynamic recrystallization during deformation promotes the formation of a strong gamma-fiber texture in the alloy.

Summary: This study evaluated the microstructure evolution in two arc-welded multi-principal element alloys using electron microscopy and high energy synchrotron X-ray diffraction coupled with thermodynamic calculations. By correlating microhardness maps with microstructure characterization, the strengthening phases in the welded materials were identified, aiding in fine tuning of the alloy microstructure for targeted strengths. A comparison between thermodynamically predicted microstructure and actual welded joints highlighted the difficulty of predictions in complex, scarcely studied multi-principal element systems.

Summary: The aim of this study is to detect flaw formation in the wire-based directed energy deposition (W-DED) process using in-situ sensor data. The W-DED is similar to metal inert gas electric arc welding. The study develops and applies a novel wavelet integrated graph theory approach to detect flaw formation in W-DED parts using data acquired from an acoustic sensor. The approach achieves a false alarm rate of less than 2% in detecting the onset of various types of flaws.

Summary: A non-equiatomic interstitial-strengthened high entropy alloy (iHEA), Fe49.5Mn30Co10Cr10C0.5 (at.%), is manufactured by laser powder-bed fusion (LPBF) with stripe and chessboard scanning strategies. The relationship between laser scanning strategies and resulting microstructure, textures, and anisotropic mechanical properties in as-built iHEA is investigated. Results show that LPBF processed iHEA exhibits excellent strength-ductility synergy due to combined deformation mechanisms. The mechanical anisotropy is more evident in samples printed by the stripe scanning strategy compared to the chessboard-scanned samples, attributed to heterogeneous grain morphology and crystallographic texture resulting from different scanning strategies.

Summary: Hot corrosion studies were conducted on pristine and abrasive water jet peened (AWJP) Ti-6Al-4V surfaces. Both surfaces developed oxide scales when coated with NaCl and exposed to 600 degrees C for 100 h, but the oxide scale on the AWJ peened surface had lower thickness and roughness. The hot corrosion rate on the pristine surface was 2.5 times higher compared to the AWJ peened surface. The improved hot corrosion resistance of the latter can be attributed to compressive residual stresses on the surface, which hinder chloride diffusion in the material.

Summary: In this study, keyhole-tungsten inert gas (K-TIG) butt welding was used to join 10 mm thick Invar 36 alloy plates, and the effects of heat input on the microstructure, morphology, and mechanical properties were investigated. The results showed that regardless of the heat input, the material consisted solely of austenite, although the grain size changed significantly. The change in heat input also resulted in texture changes in the fusion zone, which were qualitatively determined using synchrotron radiation. Increases in heat input led to a decrease in the impact properties of the welded joints. The coefficient of thermal expansion of the joints was measured, demonstrating the suitability of the current process for aerospace applications.

Summary: The wire and arc additive manufacturing (WAAM) process combines the fusion and solidification of metal wire with electric arc to create and repair complex structures. However, the high number of depositions increases the likelihood of defects, and high temperatures and surface irregularity make inspection difficult. Recent studies have shown that non-destructive testing (NDT) based on different physical phenomena can significantly reduce the rejection rate, allowing for in-line repair and waste reduction.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
