High temperature mechanical behavior of a new Nickel-based alloy

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:

Metallic alloys used for high temperature applications, e.g., energy generation, have been pushed to the upper limit of their capabilities. However, there is a substantial need for stronger alloys that can withstand higher loads at high temperatures than those possible with today’s alloys. The response of any new alloy to load under high temperatures, e.g., from 500 to 1000 °C, is of extreme interest, particularly how fast they deform under constant load at temperature, e.g., thermal creep. In this project, a nickel-based alloy where two alloying elements added to the limit of their solubility in the nickel matrix will be processed from the melt and heat treated to produce precipitates. Then, samples will be fabricated from the heat treated material to perform creep experiments at different temperatures and loads so that key mechanical properties such as activation energies and stress exponents for creep behavior can be quantified experimentally and compared to those of existing commercial alloys. Some of the techniques involve include arc melting, heat treatments under controlled atmospheres, metallography, general mechanical testing, high temperature creep testing, and optical microscopy, to mention a few. Training will be provided.

Sub-Themes:

  • Energy generation
  • Gas turbines

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 MAE 529 (preferred), MAE 520 or MSE 523 (for graduate students). Those with lab experience will be given preference. GPa of at least 3.5. Mechanical, aerospace or materials engineering students can apply.
