Mechanical properties of oxidized titanium alloys at low temperatures

The manuscript considers microstructure, mechanical and processing properties (formability and solid state weldability) of sheet titanium alloy VT6(Ti-6Al-4V) with improved superplastic properties production of JSC «VSMPO-AVISMA Corporation" for the process of superplastic forming at low temperatures and new experimental cheaper sheet titanium alloy VST2k. Complex studies of microstructure, mechanical properties, formability and weldability in the solid state of these titanium alloys were carried out. Studies have shown that both alloys in the temperature range 750-850oC have good weldability in the solid state and exhibit good superplastic properties. Technological properties of the alloy VST2k almost as good as the properties of the alloy VT6. This makes it possible to recommend the sheet alloy VST2k along with the alloy VT6 for the manufacture of hollow structures by SPF/DB in low-temperature superplasticity.

Production Conditions

A simple technological method is proposed and tested experimentally, which allows for the improvement of mechanical properties in sheet two-phase high-strength titanium alloys VT23 and VT23M on the finished product (rolled metal), due to impact-oscillatory loading. Under impact-oscillatory loading and dynamic non-equilibrium processes (DNP) are realized in titanium alloys, leading to the self-organization of the structure. As a result, the mechanical properties of titanium alloys vary significantly with subsequent loading after the realization of DNP. In this study, the test modes are found, which can be used in the production conditions.

Abstract The mechanical properties of welded DH36 steel at low temperatures are important to the safety of structures in Polar areas. The purpose of the study is to investigate the static and cyclic behavior of welded DH36 steel at low temperatures based on tensile and fatigue tests. The Ductile to Brittle transition and Fatigue Ductile to Brittle Transition of welded DH36 steel occurred at low temperatures. Finally, some relevant applications of the results within the context of polar engineering and design are discussed in the last part of the present study.
