Titanium (Ti) — 10-Year Trends

As of 2026-09-11 · the last 10 years

Titanium’s research intensity currently sits at about 96% of its own all-time peak, a level reached within this window in 2021.

Research intensity ran from about 97% of the element's own all-time peak in 2016 to about 96% in 2026 — essentially flat across the window, and the all-time peak (2021) falls inside this window. Over the same span its share of research attention across all elements rose. Among the 118 elements, titanium has a larger-than-average research literature.

The number of papers involving the element rose from about 49,664 in 2016 to about 91,597 in 2025 (1.84x). That is slower than the literature as a whole grew over the same years, so the element lost ground in the wider body of research even as its own count rose.

The largest share of titanium’s recent research belongs to Electron Beam Additive Manufacturing of Titanium Alloys, a community focused on electron beam melting of Ti-6Al-4V and pure titanium, analyzing microstructure evolution and mechanical properties. Titanium is one strand of a broader community, with about 15% of its papers involving the element. This group accounts for about 20% of the element's recent research, a steady share compared to the previous period. A key anchor is a 2022 review on high-strength titanium alloys for aerospace engineering, cited over 760 times, alongside a 2024 Nature paper on high fatigue resistance in 3D-printed titanium, cited over 280 times.

Titanium Surface Engineering for Orthopaedic and Dental Implants forms the second major pillar, where work centers on modifying titanium surfaces, coatings, and porous structures to enhance implant integration. Here, titanium is also a specific strand within a broader biomedical community, representing about 14% of those papers. It holds about 13% of titanium’s recent research, remaining steady over the last decade. A 2019 review on titanium alloys as biomaterials for orthopaedic applications, cited over 1,400 times, remains a foundational text, while a 2024 comprehensive review of titanium-based alloys and composites for orthopedic implants, cited over 460 times, reflects current interest.

The third material community is Titanium Dioxide Nanomaterials for Photocatalysis, which focuses on synthesizing and doping TiO2 nanoparticles and thin films for photocatalytic degradation and hydrogen production. Titanium is central to this specific subfield, though it constitutes about 15% of the broader photocatalytic community. This area represents about 10% of titanium’s recent research, a steady share. The 2017 Chemical Reviews paper on the generation and detection of reactive oxygen species in photocatalysis, cited over 4,700 times, is the most cited work in this group, while a 2024 review on anatase and rutile TiO2 nanoparticles, cited over 250 times, highlights ongoing applications.

Across these three named communities, the composition of titanium’s research has remained remarkably stable, with no single group gaining or losing significant ground relative to the others. The remainder of the element's research, which includes diverse applications in energy storage and thin films, holds about 57% of the total, a share that has also remained steady. This stability suggests a mature field where core applications in manufacturing, biomedicine, and photocatalysis continue to dominate the literature.
