A recent breakthrough in steel manufacturing has been achieved by Dr. Kingsley Amatanweze, a 2025 Ph.D. graduate from Missouri University of Science and Technology (Missouri S&T).
His research offers innovative solutions to reduce cracking and distortion during the heat treatment phase — issues that have long plagued industries like automotive, defense, and heavy manufacturing.
Focus on Strength and Efficiency
Amatanweze concentrated on a high-strength, lightweight steel alloy composed of chromium, molybdenum, and nickel.
Under the mentorship of Dr. Laura Bartlett, Associate Professor of Metallurgical Engineering, he investigated methods to optimize induction melting, pouring, and cooling — crucial stages in the steelmaking process.
His most significant advancement was in the quenching phase, where steel is rapidly cooled to harden it. He compared a spray water-quenching method developed at Missouri S&T to traditional oil or water immersion.
The spray technique delivered more uniform cooling, minimized crack formation, and proved especially effective for complex-shaped components.
“Water spray quenching offers a safer, cleaner, and more sustainable solution for manufacturers,” said Amatanweze.
Cleaner Steel, Fewer Defects
Amatanweze also tackled defects in earlier manufacturing stages:
- In the melting phase, he discovered that argon gas shielding and dome covers significantly reduce nitrogen absorption, which can lead to gas pockets and weakened steel.
- He optimized alloy addition timing and minimized holding times at high temperatures to enhance steel purity.
- In the mold-filling stage, he tested redesigned gating systems to limit turbulence and better trap impurities.
Global Recognition and Academic Excellence
His dedication earned him global accolades:
- Named a student trustee of ASM International in 2023.
- Winner of the 2024 ASM Best Student Paper Award.
ASM International, formerly the American Society for Metals, is a leading organization for materials engineers and scientists worldwide.
Amatanweze credits much of his growth to his academic support system at Missouri S&T.
“My professors truly cared and prepared us for real-world success,” he said.
Through his pioneering work, Dr. Kingsley Amatanweze is shaping the future of steel production by promoting stronger, cleaner, and more efficient methods.
His innovations not only reduce waste and cost but also advance sustainability and safety in manufacturing. With leaders like Amatanweze, the field of metallurgical engineering continues to evolve, powering industries that rely on cutting-edge materials science.
