Thermal Modeling Of Additive Manufacturing Using Graph Theory: Validation With Directed Energy Deposition, Jordan Severson

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Metal additive manufacturing (AM/3D printing) offers unparalleled advantages over conventional manufacturing, including greater design freedom and a lower lead time. However, the use of AM parts in safety-critical industries, such as aerospace and biomedical, is limited by the tendency of the process to create flaws that can lead to sudden failure during use. The root cause of flaw formation in metal AM parts, such as porosity and deformation, is linked to the temperature inside the part during the process, called the thermal history. The thermal history is a function of the process parameters and part design.

Effect Of Shot Peening On Stress Corrosion Behavior Of Biodegradable Magnesium We43, Tejaswita Patil

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Conventionally used metals for orthopedic devices made of titanium, stainless steel, and Co-Cr alloys are designed to be permanently implanted. However, long-term complications arise and a secondary implant removal surgery is often necessary. A mismatch in stiffness between the bone and implant results in stress shielding that negatively affects bone density. To overcome these problems, magnesium alloys (e.g., WE34) are favored due to a lower Young’s modulus (45 GPa) and biodegradability. The critical technical barrier with magnesium alloys is their high corrosion rate in physiological (salt-based) environments. One solution is to use surface treatments, such as shot peening (SP), to …
