Abstract

Now that an industrial-scale low-cost production route for ballistic-grade titanium is within reach, the potential use of titanium armour could depend on a solution for the spalling of high strength titanium. This paper addresses a titanium based metal laminate as being a possible solution for the use of titanium in armour concepts. Autodyn-2D is used in a numerical study to qualify possible configurations. This so-called experiment design resulted in a preliminary experimental program and will be presented. Another question to be addressed in this paper is whether magnesium alloys can be used as armour material. Despite current limitations on available magnesium alloys useful for armour applications, its potential ballistic performance is shown by experimental results of armour configurations with magnesium alloys against a limited number of threats
