Superelasticity degradation of NiTi shape memory alloy in wide ranges of temperature and loading level: Experimental observation and micromechanical constitutive model

Di Song et al.

Summary: In this study, cyclic tension-unloading tests were conducted to investigate the effects of temperature and loading level on the cyclic deformation behavior of NiTi shape memory alloy wires. The superelasticity degradation was observed and aggravated with the increase of temperature and loading level, attributed to the complex interactions among different deformation mechanisms. A micromechanical cyclic constitutive model was proposed based on irreversible thermodynamics and Eshelby's inclusion theory. The model was validated and used to discuss the dominant plastic deformation mechanisms and their effects on the cyclic deformation of NiTi SMA.

Achieving superelasticity in additively manufactured Ni-lean NiTi by crystallographic design

Jia-Ning Zhu et al.

Summary: In this study, a novel framework of multi-scale models enabling texture and microstructure design is proposed for high-performance NiTi fabrication. By creating a (001) texture and employing Ni-lean Ni(49.4 at. %)-Ti alloy, a 4% high-temperature compressive superelasticity is achieved for the first time. The unprecedented superelasticity can be maintained up to 453 K and has a wider temperature range compared to previous alloys.

Superelastic response and damping behavior of additively manufactured Nitinol architectured materials

Zhaorui Yan et al.

Summary: In this study, NiTi architectured materials with anisotropic superelastic response, recoverable energy absorption and damping were successfully manufactured using laser powder bed fusion (L-PBF). Numerical models showed that the superelastic and effective transformation stress of NiTi materials can be controlled by relative density and cell architecture. Cyclic compressive tests demonstrated stable reversible strain and damping behavior without yielding damage or plastic buckling, indicating that progressive martensitic transformation is the main mechanism for deformation and energy dissipation. The integration of computational and experimental approaches allows tailoring of superelasticity through structural design and microstructural control.

Exceptional fatigue life and ductility of new liquid healing hot isostatic pressing especially tailored for additive manufactured aluminum alloys

Julie Gheysen et al.

Summary: Porosity and hot cracking are still obstacles to the introduction of new additive manufactured alloys on the market, which requires high reliability. Hot Isostatic Pressing (HIP) is commonly used to eliminate these defects, but it is detrimental to aluminum alloys. Liquid assisted healing during HIP is applied to compress and completely heal the pores, leading to a substantial increase in fracture strain and fatigue life. This healing HIP treatment shows promise for post-treatment of other Al alloys and in-service healing.

The limit of hot isostatic pressing for healing cracks present in an additively manufactured nickel superalloy

M. Vilanova et al.

Summary: This paper discusses the issue of cracking in Inconel 738LC superalloy during Laser Powder Bed Fusion manufacturing, and the significant reduction of these cracks through Hot Isostatic Pressing post-treatment. The research reveals a crack width limit of 6 microns, beyond which the HIP treatment is unable to heal the cracks.

Controlling microstructure evolution and phase transformation behavior in additive manufacturing of nitinol shape memory alloys by tuning hatch distance

Jia-Ning Zhu et al.

Summary: The effect of hatch distance on microstructure and functional properties of L-PBF NiTi shape memory alloys is investigated. It is found that the phase transformation temperatures do not decrease proportionally with hatch distance, but rather relate to a critical value. Below this critical value, epitaxial grain growth and in situ recrystallization are enhanced, while above, irregular grains and decreased dislocations are formed. However, the critical value exhibits high dislocation density and fine grain size, resulting in superior thermal cyclic stability.

Review of high-strength aluminium alloys for additive manufacturing by laser powder bed fusion

Paul A. Rometsch et al.

Summary: In recent years, there has been a growing demand in industries for the development of high-strength aluminium alloys for LPBF, but challenges remain in printability and defect control. To achieve high strength with printability, possible strategies include adapting existing high-strength alloys, designing new alloys specifically for LPBF, and developing aluminium-based composites.

Effects of process parameters on microstructure and cracking susceptibility of a single crystal superalloy fabricated by directed energy deposition

Zhipeng Zhou et al.

Summary: In this study, multi-track block samples were fabricated using the directed energy deposition technique. The effects of process parameters on cracking susceptibility were analyzed, and crack-free SX blocks were successfully achieved by adjusting the parameters. These findings provide guidance for reducing cracking susceptibility and fabricating large-scale crack-free SX blocks using the DED technique.

Micro-cracking, microstructure and mechanical properties of Hastelloy-X alloy printed by laser powder bed fusion: As-built, annealed and hot-isostatic pressed

Hui Wang et al.

Summary: This study analyzed literature data to identify optimized print parameters and evaluated the consolidation, microstructure, and mechanical properties of Hastelloy-X printed by laser powder bed fusion. The results showed that hot-isostatic pressing (HIP) was more effective in removing internal micro-cracks and pores, as well as optimizing mechanical properties through recrystallization and precipitation compared to annealing.

Lattice Defects Generated by Cyclic Thermomechanical Loading of Superelastic NiTi Wire

Ondrej Tyc et al.

Summary: The cyclic instability of stress-strain-temperature functional responses of NiTi is likely due to plastic deformation accompanying martensitic transformation under external stress. Systematic experimental evidence on this was obtained through cyclic thermomechanical loading tests on superelastic NiTi wires with nanocrystalline microstructure, showing that responses were stable at low stresses during martensitic transformation and unstable at high stresses with large accumulated unrecovered strains and deformation defects.
