Microstructure Dual-Refinement and Mechanical Properties Manipulation of TiBw/TA15(Si) Composites by Thermo-mechanical Processing and Heat Treatment
… and good high-temperature strength. However, the thermo-mechanical processing is limited by the brittleness of the reinforcement, making it difficult to refine the grain size and control the silicide precipitates. The present work aims to prepare titanium matrix composites with refined grain size …

Computational and Machine Learning-Reinforced Modeling and Design of Materials under Uncertainty
… However, variations arising from the thermo-mechanical processing of materials affect microstructural features and properties by propagating over multiple length scales. To quantify this inherent microstructural uncertainty, this study introduces a linear programming-based analytical …

Evolution of globularisation in Ti-6Al-4V alloy during secondary cogging operations under industrial scale conditions
… parameters and microstructural evolution during thermo-mechanical processing of Titanium alloys is essential to ensure that the desired mechanical properties are achieved in the final component and to reduce production costs. This thesis particularly focuses on the evolution of globularisation in …

Novel approaches for the characterisation of spinodal alloys
… is often accompanied by the formation of more thermodynamically stable phases, through processes such as discontinuous precipitation. This generally leads to softening and embrittlement and has thus precluded more widespread use of spinodal alloys. These limitations have motivated efforts to …

The influence of rough rolling conditions on austenite evolution in peritectic microalloyed plate steels
The thermo-mechanical processing of microalloyed steels has been studied widely. However most of the work has been focused on the finishing stages of hot rolling where pancaking of the austenite is desired for strength and toughness. During roughing, full recrystallization is desired for a uniform, …
