Cr+6 Controlled Nucleation in SiO2-MgO-Al2O3-K2O-B2O3-F Glass Sealant (SOFC)
Autor: Mrinmoy Garai, Basudeb Karmakar, Shibayan Roy
Publikováno v: Frontiers in Materials, Vol 7 (2020)
This study highlights the strong effect of chromium (Cr6+) as a nucleating agent for SiO2-MgO-Al2O3-B2O3-K2O-F glass sealant. In the process, Al2O3 from the base glass was gradually substituted by K2Cr2O7, which considerably tuned the crystallization

New-Age Al-Cu-Mn-Zr (ACMZ) Alloy for High Temperature-High Strength Applications: A Review
Autor: Samarendra, Roy, Shibayan, Roy
Publikováno v: Aluminium Alloys-Design and Development of Innovative Alloys, Manufacturing Processes and Applications
One of the prime challenges with age hardened Al-Cu alloys is the strength degradation at high temperatures (above ∼250°C) due to the coarsening of strengthening θ′ precipitates and associated metastable θ′ → stable θ phase transformation

Microstructure evolution and mechanical response of a boron-modified Ti-6Al-4V alloy during high-pressure torsion processing
Autor: Shibayan Roy, Amit Sharma, Atanu Chaudhuri, Yi Huang, Terence G. Langdon, Satyam Suwas
Research was conducted on the microstructural evolution and ensuing mechanical response from high-pressure torsion (HPT) processing of Ti-6Al-4V alloy in the as-cast and β-forged conditions with and without 0.1 wt.% boron addition. The boron additio
