Capstone Design Expo Posters

The senior design project ‘Alternative Materials and Methods for Dental Restoration’ has a purpose of addressing the unmet need or engineering problem related to dental restoration by determining the available manufacturing methods and materials as an alternative to ‘Intra-oral digital scanners’. The project deliverables for this project were the tooth crown prototypes with the tolerance within 50 microns. The CAD model for this tooth was tested for its strength, physical properties, and suitability. The prototypes were developed through an additive method, i.e., 3D printing. The constraints for this project were related to budget and printer. Buying a highly qualitative 3D …

Deformation Induced Martensitic Transformation In 304 Stainless Steels, Junliang Liu

Theses and Dissertations

304 stainless steel is an austenitic steel widely used for various applications due to a good combination of strength and ductility and relative low cost. It is known to be metastable as the austenite phase can transform into martensite under stress. In this work, a new method (in-situ tensile TEM) and the traditional method (ex-situ tensile tests and TEM, XRD characterization) were used to investigate the mechanisms of deformation-induced martensitic transformation in 304SS samples at different temperatures.

The ex-situ tensile tests were conducted under a strain rate of 10-3 s-1 until rupture. After the tensile tests, the fractured area was …
