Cobalt-Controlled Interphase Partitioning Regulates Matrix Solute Transport and Coarsening in Ti-Rich NiCoCr-Based Superalloys
Sudeepta Mukherjee, Surendra Kumar Makineni, B. S. Murty +1
The microstructural stability and mechanical response of superalloys at elevated temperatures are governed by solute chemistry and elemental partitioning across the h…
High-strength and ductile lightweight cast aluminium alloys with superlattice nano-layered fibres (SNL) and core-shell nano-particles
Hemant Kumar, Praveen Kumar, Dierk Raabe +2
Lightweight, high-strength structural materials are component enablers in transportation and aerospace, reducing carbon footprints and enhancing fuel efficiency. Cast aluminium all…
An Experimental Estimation Method of Diffusion Coefficients in Ternary and Multicomponent Systems from a Single Diffusion Couple Profile
Suman Sadhu, Anindita Chakraborty, Surendra Makineni +2
Until recently, it was textbook knowledge that the diffusion coefficients could not be estimated in a multi-component system following the widely practised diffusion couple method.…
Chemical heterogeneity enhances hydrogen resistance in high-strength steels
Binhan Sun, Wenjun Lu, Ran Ding +7
When H, the lightest, smallest and most abundant atom in the universe, makes its way into a high-strength alloy (>650 MPa), the material's load-bearing capacity is abruptly lost. T…
Microstructural engineering of medium entropy NiCo(CrAl) alloy for enhanced room and high-temperature mechanical properties
Nithin Baler, Abdulla Samin M, Akshat Godha +1
This work demonstrates the development of a strong and ductile medium entropy alloy by employing conventional alloying and thermomechanical processing to induce partial recrystalli…
Understanding creep of a single-crystalline Co-Al-W-Ta superalloy by studying the deformation mechanism, segregation tendency and stacking fault energy
Nicklas Volz, Fei Xue, Christopher H. Zenk +9
A systematic study of the compression creep properties of a single-crystalline Co-base superalloy (Co-9Al-7.5W-2Ta) was conducted at 950 °C, 975 °C and 1000 °C to reveal the influe…
On the effect of Re addition on microstructural evolution of a CoNi-based superalloy
P. Pandey, A. K. Sawant, B. Nithin +4
In this study, the effect of rhenium (Re) addition on microstructural evolution of a new low-density Co-Ni-Al-Mo-Nb based superalloy is presented. Addition of Re significantly infl…
On the segregation of Re at dislocations in the γ' phase of Ni-based single crystal superalloys
Xiaoxiang Wu, Surendra Kumar Makineni, Paraskevas Kontis +4
We report evidence of Re and Mo segregation (up to 2.6 at.% and 1 at.%) along with Cr and Co to the dislocations inside of γ' precipitates in a second generation Ni-based single cr…
