Authors -F Micheal Raj, Professor Obisian R.K

Abstract- – Cryo-rolling is an advanced metal forming technique performed at cryogenic temperatures, typically using liquid nitrogen, to enhance the mechanical and microstructural properties of metals and alloys. This study presents a comprehensive analysis of the cryo-rolling process, emphasizing its effects on grain refinement, dislocation density, and mechanical enhancement across various materials including aluminum, magnesium, titanium, copper, steels, and high-entropy alloys. Key process parameters—such as rolling speed, reduction ratio, and number of passes—were evaluated alongside the design considerations for cryogenic rolling equipment. The study also explores microstructural transformations including texture evolution, precipitate distribution, and phase changes. Mechanical testing, including tensile, hardness, and impact strength, confirmed improved performance post-processing. Advanced simulation tools like finite element analysis (FEA) were used to model stress-strain behavior and thermal conditions. Applications in aerospace, automotive, biomedical, and cryogenic systems highlight the process’s industrial relevance. Future directions in hybrid rolling techniques, additive manufacturing integration, and cryo-electron microscopy-based analysis further emphasize cryo-rolling’s growing significance in modern material science.
