The Ti-6Al-4V alloy is considered one of the most widely used titanium alloys in various industries, including aerospace, medicine, and others, due to its high strength, low density, suitable fatigue resistance, and desirable thermal stability. The desirable mechanical performance of this alloy is largely dependent on the final microstructure and the conditions of the forming processes. In this study, the mechanical behavior of a forged Ti-6Al-4V blade under tensile loading was investigated with a focus on the analysis and optimization of forging process parameters. The forging operation was performed in both longitudinal and transverse directions, and tensile test specimens were extracted from the forged regions in accordance with the relevant standards. Mechanical properties, including yield strength and ultimate tensile strength, were evaluated at room temperature and under a constant strain rate. The results indicated that specimens forged in the longitudinal direction exhibited a yield strength of 993.1 MPa and an ultimate tensile strength of 1003.4 MPa. These values represent an approximately 5.9% increase compared with those of the specimens forged in the transverse direction, demonstrating the significant effect of forging direction on microstructural alignment, strain distribution, and ultimately the enhanced mechanical performance of Ti-6Al-4V alloy blades.
