Effects of Composition on Microstructural Stability and Hardness of New Nickel-based Alloys

Dr. Pedro Peralta, a Professor for the School of Mechanical and Aerospace Engineering of the Ira A. Fulton Schools of Engineering has a research opening for the following project:

Existing metallic materials for demanding conditions, e.g., Nickel-based superalloys, have excellent mechanical and corrosion properties over a wide temperature range. A key characteristic of these alloys is the stability of their microstructure as both load and temperature increase. However, many of these alloys are reaching the upper limit of their capability to withstand the extreme environments typical of energy generation applications, i.e., high temperature, high stress, and corrosion. This project aims to fabricate, heat treat and test a new class of Nickel-based alloy using alloying elements that are different from those traditionally used in commercial Ni-based alloys, with emphasis on studying microstructural stability and hardness of the new alloys as a function of composition to find optimum microstructures. Some of the techniques involve include arc melting, heat treatments under controlled atmospheres, metallography, hardness testing, optical and electron microscopy, to mention a few. Training will be provided.

Sub-Themes:

  • Mechanical properties
  • Heat treatments
  • Advanced alloys

Student qualifications/requirements: 

Motivated individuals, with strong skills for self- and guided learning are needed for this project. Must have an A in MAE 213 or MSE 211 (for undergrads) or an A in either MSE 523 (preferred), MAE 520 or MAE 529 (for graduate students). Those with lab experience will be given preference. Strong interest in structure-property relations GPa of at least 3.5. Materials, mechanical, or aerospace engineering students can apply.
