TLDR
In this article, the effects of varying welding procedures on HAZ toughness of 12 % Cr martensitic-ferritic steels were examined, and two commercial base metals were selected of 12mm (0.5in) thickness, varying in martensite-ferrite balance, and stabilized by Ti additions.Abstract:
The present work was done to examine the effects of varying welding procedures on HAZ toughness of 12 % Cr martensitic-ferritic steels. Two commercial base metals were selected of 12-mm (0.5-in.) thickness, varying in martensite-ferrite balance, and stabilized by Ti additions. Shielded metal arc (SMA) square-groove welds were made using 23 % Cr-12 % Ni electrodes, with Charpy impact tests on specimens notched through the thickness in the high-temperature HAZ. Further toughness testing was carried out on simulated HAZ samples produced using thermal cycles derived from actual weld runsread more

Mechanisms of Epithelial Cell–Cell Adhesion and Cell Compaction Revealed by High-resolution Tracking of E-Cadherin– Green Fluorescent Protein
TL;DR: A model is proposed to explain how, through strengthening and compaction, E-cadherin and actin cables coordinate to remodel initial cell–cell contacts to the final condensation of cells into colonies.
