A Nigerian materials engineer based in the United States, Engr. Reuben Zakari Kabantiyok, FNMS, has presented new research demonstrating how the performance of advanced metallic materials can be improved without compromising their durability, in a development that aligns with Nigeria’s drive towards value addition and industrial transformation.
Kabantiyok, who is affiliated with the University of Tulsa, United States, presented the findings as a plenary speaker at the 41st Annual Conference and Annual General Meeting of the Nigerian Metallurgical Society (NMS), which was held in Abuja.
His research focused on nickel-titanium (NiTi) shape memory alloys, demonstrating that their functional performance could be enhanced through surface modification and aging without reducing their fatigue life under repeated loading.
The conference, tagged “Abuja Hybrid 2026,” was held from October 28 to 31 at the Raw Materials Research and Development Council (RMRDC), Abuja, in collaboration with the Council and other organisations in the metallurgical, minerals, materials and mining sectors.
The Minister of Steel Development, Prince Shu’aibu Abubakar Audu, was the Chief Host and Keynote Speaker.
Speaking virtually from the United States, Kabantiyok explained that his research addressed an important challenge in materials engineering: how to improve the functionality of advanced alloys while preserving their ability to withstand prolonged use.
“The results show that the functional response of NiTi can be tuned without a measurable penalty to structural fatigue life up to 10 million cycles,” he said.
NiTi shape memory alloys are widely used in biomedical devices and engineering applications because of their unique ability to recover their original shape after undergoing substantial deformation. They also possess superelastic properties that make them valuable in applications requiring flexibility, resilience and durability.
However, improving the functional properties of these materials has raised concerns about whether surface modifications and other treatments could negatively affect their long-term structural performance.
To investigate this challenge, Kabantiyok’s research involved coating NiTi samples with a thin titanium dioxide (TiO₂) film using Atomic Layer Deposition (ALD), a specialised technique that produces highly controlled coatings one atomic layer at a time.
The study also examined aged samples and employed fatigue testing alongside Digital Image Correlation (DIC), an advanced imaging technique used to monitor strain localisation and track damage development as materials undergo repeated loading.
The findings demonstrated that the functional response of NiTi alloys could be tailored while maintaining their structural fatigue performance for up to 10 million cycles.
The research is particularly relevant to the theme of this year’s conference, “Innovative Metal Production and Strategic Minerals’ Value Addition for Economic and Industrial Transformation.”
It reinforces the growing importance of moving beyond the extraction and processing of raw materials to developing high-performance, value-added products capable of meeting demanding industrial, engineering and biomedical requirements.
The presentation also highlighted how advanced materials research can contribute to Nigeria’s industrial development by strengthening local technical knowledge, encouraging innovation and creating opportunities for higher-value applications of strategic metallic resources.
Beyond its scientific significance, Kabantiyok’s participation underscored the importance of the conference’s hybrid format in connecting Nigerian professionals and researchers in the diaspora with developments in the country’s metallurgical and materials industries.
The four-day conference brings together metallurgists, materials engineers, researchers, industry practitioners and policymakers to exchange ideas, showcase innovations and explore partnerships across Nigeria’s metals, minerals and materials value chain.
Participants are engaging through oral presentations, poster sessions, virtual presentations and exhibitions, while accepted research papers are expected to be published in the Society’s journals.
Kabantiyok, a Fellow of the Nigerian Metallurgical Society, specialises in the fatigue behaviour and surface engineering of nickel-titanium shape memory alloys, with research interests focused on improving the performance and reliability of advanced engineering materials.
The Nigerian Metallurgical Society, the flagship professional body for the metals, minerals and materials industries in the country, uses its annual conference as a platform for professional networking, knowledge exchange and discussions on policies and practices capable of advancing the sector.
His presentation has added an important research perspective to the national conversation on strategic minerals and industrial transformation, demonstrating how scientific innovation and advanced materials engineering can help convert materials into higher-value products for specialised applications.
