Effect of rejuvenation heat treatment on re-service aging stability of γ′phase in directionally solidified superalloy

open access: yesJournal of Aeronautical Materials, 2021
High temperature aging treatment was first conducted on the rejuvenated directionally solidified superalloy to simulate the re-service aging damage of turbine blades and the virgin directionally solidified superalloy respectively.

Cell aging preserves cellular immortality in the presence of lethal levels of damage. [PDF]

open access: yes, 2019
Cellular aging, a progressive functional decline driven by damage accumulation, often culminates in the mortality of a cell lineage. Certain lineages, however, are able to sustain long-lasting immortality, as prominently exemplified by stem cells.

Relaxation dynamics of Fe55Cr10Mo14C15B6 metallic glass explored by mechanical spectroscopy and calorimetry measurements [PDF]

open access: yes, 2016
In this work, the mechanical relaxation dynamics of Fe55Cr10Mo14C15B6 metallic glass is explored by mechanical spectroscopy. The temperature-dependent loss modulus E″(T) shows the features of β relaxation well below glass transition temperature Tg.
