Abhinav’s work on “Additively manufactured Co–Cr–Ni multi-principal element alloys with excellent strength and ductility at room and cryogenic temperatures,” was recently published in Virtual and Physical Prototyping.

This study explores the directed energy deposition (DED) of two non-equiatomic CoCrNi alloys engineered with tailored stacking fault energies—one high-SFE (HSFE) and one low-SFE (LSFE)—alongside an equiatomic variant for benchmarking. Mechanical testing revealed that LSFE outperformed HSFE in yield strength at both 298 K and 77 K, thanks to its higher Cr content and lower SFE. At room temperature, LSFE showed enhanced work hardening via twinning, while at cryogenic temperatures, both alloys activated dislocation slip, twinning, and ϵ-martensite formation. LSFE achieved >1 GPa strength with ~45% ductility at 77 K, while HSFE retained ~74% ductility with >800 MPa strength.

Chethan's work on "Proton-irradiation and post-irradiation annealing behavior of a CoCrFeMnNi-based multi-principal element alloy," published in Materials Science and Engineering A. Congrats :-)

This work presents a detailed investigation into the effects of proton irradiation on the microstructure, mechanical response, and deformation mechanisms of CoCrFeMnNi-based MPEA, along with its recovery during post-irradiation annealing (PIA). High-resolution TEM analysis offered key insights into defect nature, their evolution, and annealing kinetics, revealing the alloy’s response to extreme irradiation environments.

Chethan presented this research at EMSI 2025, earning the Best Oral Presentation Award for his clarity and scientific impact.

• July 15th, 2025: Conference Update | EMSI 2025

We’re delighted to share that our group members, Shubham, Chethan, and Aparajita, participated in the International Conference on Electron Microscopy and XLIII Annual Meeting of the Electron Microscope Society of India (EMSI 2025), held from July 12 to 14, 2025.

They showcased our group’s recent advances in multicomponent alloy research through talks on:

• Fatigue-resistant FCC MPEAs

• Proton irradiation response of FCC MPEAs

• Deformation mechanisms in BCC+B2 MPEAs

Shubham and Chethan were honoured with Best Talk awards for their outstanding contributions.

Below are some moments captured from the conference:

• July 1st, 2025: 

🌟 Wrapping up a fruitful internship summer at the EEMG, IISc! 🌟

This summer, we hosted two curious interns:

🔹 Ms. Sai Samskruthi Bysani (B.Tech., NIT Warangal), who worked on applying machine learning to predict the mechanical behavior of austenitic steels.

🔹 Mr. Prithwiraj Bhowmick (B.S., IISER Berhampur), who studied how tempering time influences the mechanical properties of extruded ODS steels.

Here are a few snapshots from their final presentations and farewell.

Wishing them all the best as they continue their academic and professional journeys!
