Abstract

Nanostructured bainite-austenite steels are applied in the armours construction due to their excellent combination of strength and ductility which enables to lower the armour weight and to improve the protection efficiency. Mechanical properties of the bainite-austenite steels can be controlled in the wide range by chemical composition and heat treatment. In the paper the results of investigation comprising measuring of quasi - static mechanical properties, dynamic yield stress and firing tests of bainite-austenite steel NANOS-BA® are presented. Reported results show that the investigated bainite-austenite steel can be used for constructing add-on armour and that the armour fulfils requirements of protection level 2 of STANAG 4569. Obtained reduction in weight of the tested NANOS-BA® plates in comparison with the present solutions is about 30%.

Abstract

In numerous 15th and 16th century Fightbooks several sets of teachings appear alongside the glosses of Liechtenauer’s Epitome on armoured fighting and fighting on horseback (Harnischfechten and Rossfechten) often enough to be considered auctoritas on these subjects. However, their authorship from various witnesses are attributed to different authorial figures - Andreas Liegnitzer, Martin Hundsfeld, Jud Lew.

From 1452 until 1570, a number of diverse teachings are ascribed to them or faithfully reproduced without attribution: the most widely copied include the entitled Shortened sword for armoured hand and Shortened sword from the four guards, sword and buckler, dagger, wrestling and fighting on horseback. By a comparative analysis of existing witnesses, and by establishing the filiation tree of the related sources, we attempt to determine their original authorship. The analysis also yields additional conclusions regarding the influence of these authorial figures on other texts, proposes the filiation tree of the examined witnesses and presents the attempted study as a model for further research.
