Medium manganese steels fall into the category of modern third-generation high-strength steels. Thanks to their alloying, they use a number of strengthening mechanisms, such as the TRIP and TWIP effects, to achieve their mechanical properties. The ex

Přestože lamelové zbroje, tzv. brigantiny, patří k pokročilým typům středověkých zbrojí, postrádáme u většiny dochovaných exemplářů, torz či ojedinělých nálezů lamel informace o jejich materiálových vlastnostech, způsobu z
