Influence of volumetric energy density on the tribological behaviors of pure nickel fabricated by laser powder bed fusion (2023)
Journal Article
Yue, T., Zou, Z., Zhang, S., Xu, Y., & Zang, Y. (2023). Influence of volumetric energy density on the tribological behaviors of pure nickel fabricated by laser powder bed fusion. Virtual and Physical Prototyping, 18(1), Article e2262449. https://doi.org/10.1080/17452759.2023.2262449

Laser powder bed fusion (L-PBF) enables the fast fabrication of pure nickel parts with complex structures. Tribological behaviors of the printed pure nickel are crucial to its application, and highly dependent on the volumetric energy density (VED),...

The development of ultrafine grain structure in an additively manufactured titanium alloy via high-temperature microscopy (2023)
Journal Article
Simonelli, M., Zou, Z., Barriobero-Vila, P., & Tse, Y. Y. (2023). The development of ultrafine grain structure in an additively manufactured titanium alloy via high-temperature microscopy. Materialia, 30, Article 101856. https://doi.org/10.1016/j.mtla.2023.101856

Microstructures dominated by acicular α' martensitic phase, such as in the case of Ti-6Al-4V fabricated by laser powder-bed fusion (PBF-LB), are known to suffer from reduced ductility and low toughness. The decomposition of such metastable microstruc... Read More about The development of ultrafine grain structure in an additively manufactured titanium alloy via high-temperature microscopy.

Effect of Heat Treatment on the Microstructure and Mechanical Properties of Additive Manufactured Ti-6.5Al-2Zr-1Mo-1V Alloy (2022)
Journal Article
Zhang, S., Zhang, Y., Qi, J., Zou, Z., & Qian, Y. (2023). Effect of Heat Treatment on the Microstructure and Mechanical Properties of Additive Manufactured Ti-6.5Al-2Zr-1Mo-1V Alloy. Materials, 16(1), Article 160. https://doi.org/10.3390/ma16010160

Ti-6.5Al-2Zr-1Mo-1V (TA15), widely used in the aerospace industry, is a medium- to high-strength, near-α titanium alloy with high aluminium equivalent value. The TA15 fabricated via laser powder bed fusion (L-PBF) normally presents a typical brittle...

The microstructure and tensile properties of additively manufactured Ti–6Al–2Zr–1Mo–1V with a trimodal microstructure obtained by multiple annealing heat treatment (2021)
Journal Article
Zhang, S., Zhang, Y., Zou, Z., Shi, Y., & Zang, Y. (2022). The microstructure and tensile properties of additively manufactured Ti–6Al–2Zr–1Mo–1V with a trimodal microstructure obtained by multiple annealing heat treatment. Materials Science and Engineering: A, 831, Article 142241. https://doi.org/10.1016/j.msea.2021.142241

Unlike acicular martensite, combining a lamellar and equiaxed α microstructure is known to impart high ductility for Ti-6.5Al–2Zr–1Mo–1V (TA15). In this article, we report innovative heat treatment aimed at optimizing the mechanical properties of add...
