Performance Comparison of Al–Ti Master Alloys with Different Microstructures in Grain Refinement of Commercial Purity Aluminum
Three types of Al-5Ti master alloys were synthesized by a method of thermal explosion reaction in pure molten aluminum. Performance comparison of Al-5Ti master alloy in grain refinement of commercial purity Al with different additions (0.6%, 1.0%, 1.6%, 2.0%, and 3.0%) and holding time (10, 30, 60 and 120 min) were investigated. The results show that Al-5Ti master alloy with blocky TiAl₃ partic...
متن کاملMechanical properties and microstructures of dental cast Ti-Ag and Ti-Cu alloys.
In this study, experimental Ti-Ag alloys (5, 10, and 20 mass% Ag) and Ti-Cu alloys (2, 5, and 10 mass% Cu) were made in an argon-arc melting furnace. The alloys were cast into magnesia molds using an argon gas-pressure dental casting machine, and the mechanical properties and microstructures of the castings were investigated. As the concentration of silver or copper in the alloys increased, the...
متن کاملDIFFICULTIES IN GRAIN REFINING ALUMINUM LITHIUM ALLOYS USING COMMERCIAL Al-Ti AND Al-Ti-Bor MASTER ALLOYS
High strength aluminum alloys, especially those containing zirconium, are historically difficult to grain refine. Early efforts by Alcoa indicated that the addition of lithium to these alloys increases difficulty with grain refinement. Although grain refining of alloys 2090 and 2091 was possible, consistent results were not obtained. Statistically-designed experiments were used to quickly ident...
متن کاملMechanical Properties of a Newly Additive Manufactured Implant Material Based on Ti-42Nb
The application of Ti-6Al-4V alloy or commercially pure titanium for additive manufacturing enables the fabrication of complex structural implants and patient-specific implant geometries. However, the difference in Young's modulus of α + β-phase Ti alloys compared to the human bone promotes stress-shielding effects in the implant-bone interphase. The aim of the present study is the mechanical c...
متن کاملCharacterization of Additive Manufactured Objects
Hybrid Layered Manufacturing (HLM) combines the benefits of both subtractive and Additive Manufacturing (AM). In this paper authors did characterization of AM components by using Kernel Average Misorientation (KAM), Electron Backscatter Diffraction (EBSD) and hardness tester. The main focus is on matrix integrity during Gas Metal Arc Welding (GMAW) deposition and surface quality during machinin...
