An experimental investigation on the influence of geometrical configuration of copper patches on mechanical strength of cracked titanium components using diffusion method
The orientation and shape of joints in cracked structures significantly impact the mechanical behavior of components and the optimization of the construction process. This study investigates the mechanical behavior of titanium grade 2 cracked components under quasi-static tensile loads, considering the crack length (central cracks of 1, 2, and 3 cm) and patch type (rectangular, oval, and hexagonal shapes) parameters. patch connections to the 50 × 40 × 0/5 mm titanium grade 2 base plate are examined according to ASTM E 8/E 8M – 08 and ASME SA-370 standards. A novel approach to patch connection is employed using the advanced diffusion method (SPS) at a temperature range of 820-850 degrees Celsius and a pressure of 47-50 megapascals, with potential applications in the aerospace industry. A scanning electron microscope (SEM) is used to investigate the quality of the joint area of the cracked pieces joined together. Results show that an increase in crack length leads to a decrease in component resistance under static tensile loading. The hexagonal patch demonstrates better resistance with averages of 0/534 and 0/691 compared to rectangular and oval patchs, respectively, due to its superior stress distribution along the entire length of the cracks.
