Investigations of properties and microstructure bimetallic joints titanium-carbon steel, titanium-316L stainless steel obtained by explosive technique

Abstract

Numerous parts of equipment and constructions, which are exposed to work in aggressive corrosive environment and variable loads, required the use of suitable materials. These parts and structures are often made of bimetals, which consist of at least two different metals and are created by explosive welding technique. This technique allows to obtain a permanent and continuous connection with adhesive, mechanical and diffusive character. The aim of this work was to investigate the mechanical and microstructural properties of carbon steel and stainless steel plates cladding with titanium. This thesis presents the test results of the mechanical properties and microstructure of bimetals that were made of carbon steel or stainless steel plates cladding with titanium alloy Grade 1. The scope of the work included the following tests: structural, composition, hardness, fracture and fatigue. The research was carried out by using optical microscope, scanning electron microscope and energy dispersive spectroscope. The fatigue tests and hardness tests allowed to evaluate the quality of the joints and compare the mechanical properties of manufactured bimetals. Moreover, the fatigue tests allowed to define bimetal with higher mechanical properties. The change of the mechanical properties in the cross section of joints were studied using microhardness tests, whereas the changes in structure were examined based on the metallographic tests. The fractography tests served as an evaluation of the cracking process. The summary allowed to evaluated the microstructural and mechanical properties of bimetals, and choose bimetal of which durability parameters are better.
