Abstrakt: Titanium and its alloys, such as Ti8Al1Mo1V, have gained significant importance in various industries, including chemical, aviation, aerospace, marine, and medical devices. These alloys are particularly valued for their high strength-to-weight ratio and resistance to adverse environmental conditions. In the aerospace field, titanium alloys find applications in compressor blades, turbine discs, housing inner skin, and nozzle assembly frames for jet engines. However, despite their widespread use, there is a lack of systematic reporting on the structure and properties of Ti8Al1Mo1V. To address this research gap, the present study focuses on investigating the structure and properties of Ti8Al1Mo1V alloy through specific heat treatments integrating the computational analysis. The study of experimental results by the Python programming language improved data insights and made thorough analysis easier. The alloy is subjected to a solutionizing and aging process, followed by air cooling and thermal oxidation treatments. Thermal oxidation is conducted at temperatures of 600°C, 750°C, and 900°C for durations of 6 hours, 15 hours, and 24 hours, respectively. Tensile tests and micro hardness tests are performed on the thermally oxidized samples. The micro hardness tests reveal that the hardness of the Ti8Al1Mo1V alloy is highest at the surface and gradually decreases towards the core. The maximum hardness value of 548.8 is obtained for the sample subjected to a 24-hour duration at 900°C, indicating that hardness increases with both temperature and time duration. This confirms that the extent of oxidation is directly proportional to temperature and time duration. The tensile test results indicate that both the yield strength and ultimate tensile strength decrease by 8% to 15% compared to the as-received (ASR) condition of the alloy. These findings provide insights into the structural changes and mechanical properties of Ti8Al1Mo1V alloy when subjected to specific heat treatments, contributing to a better understanding of its behavior in different environments.
