The Effect of Elastic–Plastic Mismatch and Interface Proximity on the Fracture Toughness of Ti‐TiN Thin Films

open access: yesAdvanced Engineering Materials, EarlyView.
Multilayering of TiN film with metallic Ti film is adopted to enhance the fracture resistance of TiN thin films. Plastic dissipation within Ti with process zone size of ≈250 nm, along with elastic–plastic mismatch driven changes to crack driving force enhances the crack growth resistance by ten times, enabling physics informed design of optimized ...

Metallurgy in the Early Steppes [PDF]

open access: yesArtibus Asiae, 1970
In Europe copper appeared in the middle of the third millennium B.c. in the framework of a developed technology in two marginal regions, in Spain and Portugal and on the shores of the Aegean. From both centers ready-made implements were exported over large areas mostly by sea trade.
