Metastable Beta-Titanium Multi-Principal-Element Alloys

<b>Metastable beta-titanium multi-principal-element alloys (β-Ti MPEAs) are paving the way for exciting materials science advancements, particularly for aerospace and automotive engineering industries. These alloys stay stable in the beta phase under normal conditions and transform into a martensitic phase when impacted, making them tougher and more durable thanks to the TRIP (Transformation-Induced Plasticity) mechanism and increased dislocation density. Our approach involves casting the material with minor compositional variations and optimizing it through heat treatment or thermomechanical processes. We will use XRD for phase identification, EBSD for phase and orientation analysis, and EDS for elemental composition to analyze our results. Exploring martensitic reactions, including TRIP, superelasticity, and shape memory, has practical benefits for industry and academia. In industry, such materials could make auto bodies better at absorbing energy during crashes. Fundamentally, this research helps us understand phase transitions more deeply and pushes the boundaries of materials science.</b>
