Abstract

Voestalpine Böhler Bleche GmbH & Co KG, located in Mürzzuschlag, Austria, is known as a world’s leading manufacturer of cross-rolled stainless-steel sheets. Also part of company’s portfolio are sheets and plates of tool steels, high speed steels and corrosion and heat resistant steels and especially by offering nickel base and titanium alloys, the aviation and aerospace section is accessed as well. Titanium, with its own processing requirements from the slab to the finished sheet is becoming more and more important. In the course of the development and characterization of sheet metal for the interior protection of vehicles a better understanding of Titanium and especially its Ti-6Al-4V (m%) alloy should be acquired. The long-term goal is to use the parameters of the rolling process, the subsequent heat treatment and also the prematerial to generate tailored mechanical properties. At the beginning of this work, three hot-rolled sheets which in the present form are bullet-resistent, or more precisely two Ti-6Al-4V alloys and one Ti-4Al-2.5V-1.5Fe alloy, were available. A main task was to do a microstructural characterization of these sheets. Furthermore, another sample, also hot-rolled, with a known history and knowledge of the starting material was examined to make a direct comparison with the three benchmark alloys available on the market. Because for such extreme conditions, as common in the mentioned application, no correlations to classic mechanical properties are known, another major objective of the present work was to gain a deeper understanding in this area. In a literature study, examples and solutions were worked up to carry out useful estimations for this case.
