Fatigue performance control strategy of TC11 and TC17 linear friction welded joints via annealing treatment

Frontiers in Materials
A post-weld annealing strategy was developed to control the high-cycle fatigue performance of dissimilar TC11/TC17 titanium alloy linear friction welded joints. By systematically varying the stress relief annealing temperature (590, 605, 630, and 650 °C),

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Experimental Investigation on the Fatigue Life of Ti-6Al-4V Treated by Vibratory Stress Relief

Metals, 2017
Vibratory stress relief (VSR) is a highly efficient and low-energy consumption method to relieve and homogenize residual stresses in materials. Thus, the effect of VSR on the fatigue life should be determined. Standard fatigue specimens are fabricated to
