Dyuti is working on enabling Laser Directed Energy Deposition (L-DED) additive manufacturing of Nickel-Titanium Shape Memory Alloys with a goal to manufacture multifunctional materials by grading compositions.
Her research interest includes advanced materials manufacturing and characterization of metallic materials for the development of next-generation materials for the automotive industry, aerospace, and defense sectors. Over the past decade, her research focused on material processing, alloy design, and characterization of materials including various types of steels, magnesium, aluminum, titanium, and nickel alloys for different applications of protective environment, and lightweight structural materials in automotive and aerospace industries. Her research work comprises a variety of manufacturing processes, such as Additive Manufacturing (AM), Casting, Cladding with TIG torch, and Powder Metallurgy (PM). Material characterization is conducted using high tech equipment including Electron Microscopy (SEM, EBSD), X-ray diffraction (XRD), Differential Scanning Calorimetry (DSC), MTex tool. The multidisciplinary nature of the project allowed her to gain experience with physical, and mechanical metallurgy of metallic materials, as well as gain insight into the structure-property relationship necessary for the industrial application field.
Her interest in AM and material characterization was developed during MSc work (by research) where she proposed an alternative method for metal cladding in powder preplacement processes. The materials characterization has been further extended through the experience gained during her PhD programs, where she focused on microstructure and crystallographic texture development in magnesium alloy to design lightweight structural component for the automotive industry to improve energy efficiency. Her Postdoctoral Fellow project in collaboration with Fiat Chrysler Automobiles USA, where the auto parts processed in PM technique using ferrous and non-ferrous alloys were characterized in terms of microstructure and mechanical properties. Also, her interest in physical and mechanical metallurgy in AM is expanded further through the Postdoctoral Fellow at the University of Waterloo, where the projects focused on solidification behavior related to microstructure development and characterization of 3D printed ferrous and non-ferrous alloys using Laser Powder Bed Fusion (L-PBF) AM technique.
The future work will focus on the development of next-generation advanced materials for energy, transport, marine, aerospace, and defense sectors. These advanced materials will be considered for cyclic, quasi-static, impact, corrosion, and thermal properties.
