Engineering Framework to Transfer the Lower Bound Fracture Toughness between Different Temperatures in the DBTT Region

Procedia Structural Integrity, 2016
AbstractIn this paper, an engineering framework to transfer the lower bound fracture toughness between different temperatures in the ductile–to–brittle (DBTT) temperature region is proposed and validated for 0.55% carbon steel using 0.5TSE(B) specimens. The framework requires only stress–strain curve for different temperatures as experimental data. The

Partitioning and Coarsening Dynamics of Precipitate‐Strengthened Cr‐Si Alloys: The Role of Ge, Pt, and Mo

Advanced Engineering Materials, Volume 27, Issue 9, May 2025.
The microstructure of Cr‐rich Cr‐Si‐alloys is maintained by alloying with Ge, Pt, and Mo. The effects of these elements on A15‐phase fraction, partitioning, microstructural stability, grain size, and hardness are combinable. Molybdenum is found to be the most promising alloying element for microstructural stability during high‐temperature exposure.
