Washington DC/Northern Virginia/Maryland Section Presents: Student Spotlight: Investigation of Perovskite Refractories for Preventing Metal-Mold Reactions in Titanium Metallurgy
NEW DATE: March 30, 2023

Refractory ceramics for metallurgical applications have to withstand severe corrosion and thermomechanical stresses. During investment casting of titanium alloys, metal-mold reactions occur with most conventional refractories. Unfortunately, such reactions impair the knock-out removal process of the cast part, cause detrimental changes in the alloy microstructure, and limit near-net-shape casting. I will discuss different approaches that are taken to mitigate these reactions, and focus specifically on improving ceramic mold materials. For example, I will show results from my research work how an advanced perovskite refractory, strontium zirconate, is a very promising mold material for preventing metal-mold reactions with Ti6Al4V compared to conventional alumina-based molds. I will also present how we developed a robust and relatively uncomplicated procedure to predict and examine the liquid-solid and solid-solid interactions between the titanium alloys and refractory ceramics of interest. Mitigating metal-mold reactions is important for saving time and costs associated with the mechanical or chemical removal of the reaction layers.
Sharon Uwanyuze
Sharon Uwanyuze is currently finishing up her PhD in Materials Engineering, where her research has been on understanding the role of material composition in high-temperature reactions between ceramic oxide molds and titanium alloys during melting and casting.
She is fascinated by the interconnectedness of the structure-processing-properties-performance paradigm of materials, and she seeks to learn and apply her findings to various fields. Sharon worked as an R&D Intern at Reno Refractories Inc., and a Corrosion Intern at Oak Ridge National Lab. She is now searching for full time jobs that require ceramics and non-ferrous metallurgy expertise.
Outside the lab, Sharon serves as the President of the UConn Grad Black STEM, a peer-learning community of graduate students that seeks to increase the number of culturally responsible Black scientists who excel academically, succeed professionally, and positively impact the community.

Washington DC/Northern Virginia/Maryland All Section Meeting minutes and notes from August 19, 2022
The Washington DC/Northern Virginia/Maryland All Section Meeting was August 19, 2022. The Executive Committee reviewed the proposed By Laws changes. The new ByLaws can be reviewed at this link.
The Executive Committee has asked the section membership to review these changes and respond by September 6, 2022. No responses were received and the By-Laws have been accepted. Questions and comments should be directed to Victoria Blair at victoria.l.blair3.civ@army.mil or to ACerS staff liaison, Karen McCurdy at kmccurdy@ceramics.org.
Click this link for the complete meeting minutes. Please note these discussion topics from the all section meeting:
- The officer nomination process will now be a rolling nomination process until all positions through the end of the year.
- The D & I Representative has been added to the leadership roster.
- A Meet and Greet Social Networking Event at the National Mall is being planned.
- Thesis Thursdays has been rebranded Student Spotlight. Presentations will be ad hoc. This is a good opportunity for section students to practice their presentations. A Google form will soon be posted on the webpage for presentation submissions. Student Spotlight presenters can receive a free GGRN membership!
- The section is looking for champions within specific organizations that can help with outreach on a local level. for the section within the geographic area. For example, a POC at specific organizations that can help advertise to the local level. We welcome feedback from these champions about how best to serve their organization.
Section awards MS&T conference registraitons
Congratulations to University of Virginia PhD students Clark Luckhardt and Mackenzie Ridley for being awarded MS &T conference registrations by the Washington DC/Maryland/Northern Virginia Section.
Washington DC/Northern Virginia/Maryland Section hosted meet and greet
The section gathered virtually on June 16, 2021. The Meet and Greet was an opportunity to network and share ideas until in person meetings can begin again.
