The Assessment of Mechanical Properties of Titanium Sheets Applied to Building Elevations and Roofs

Article Preview

Abstract:

Dynamic development of various industries is tightly coupled with development of new technologies and materials which are increasingly dedicated for a particular application. This regards also titanium materials, which were often applied in aerospace and maritime industries. Gradually their applications spread into automotive, energy, civil engineering industries and medicine. Titanium and its alloys are characterized by unique properties that facilitates their wide adoption in different industries. Initially application of titanium materials was constrained by its high production and processing costs. The factors contributing to application of titanium in civil engineering include high corrosion resistance, low density and low thermal conductivity. High resistance to the elements is very important when durability and long term maintenance costs of a structure are considered. In case of components exposed to action of sea water, acid rains, pollutions, application of titanium materials is advantageous in long term perspective despite its high initial costs. Additionally titanium doesn’t require protective anticorrosive coatings unlike steels and copper. Titanium sheets are applied to large area architectural structures. There are many examples of technical grade titanium applications in building elevations and roofs. For these purposes thin (0.3÷3.0 mm) sheets are selected which allow for weight reduction. In this work properties of commercially pure titanium Grade 2, 3 and 4 were researched. During experimental research the following technological and mechanical properties were determined: offset yield strength Rp02, ultimate tensile strength Rm, elongation A, planar anisotropy Δr, normal anisotropy r, and strain-hardening exponent n.
