“…6 show that the fractured surface occurs as a typical ductile fracture after the tensile test. The fracture surface is similar to the fracture surface images shown in the literature [71][72][73] and shows a typical ductile material behavior, consisting of coaxial pits alongside fluctuations and micro-voids, implying that there has been localized plastic deformation that occurred before fracture. After the corrosion test, SEM and EDS analyses were performed on the fractured surfaces of the samples with the highest weight change.…”

The corrosion resistance of laser welded samples was carried out in a shaken incubator in body-simulated liquid environments and kept at pH3-5 and 25-50˚C conditions for 24 hours. It was determined that acicular α' martensite structures were formed in the fusion regions and these structures increased the hardness of the alloy by 20% compared to the base metal. The welded samples had the highest tensile strength of 144 MPa. Weight changes after the corrosion test were calculated and the highest weight loss was found to be 0.0025 g for the sample with an initial weight of 4.1394 g. TiO2 oxides and {1 0 0} and {1 1 1} chamber-shaped salt crystals were formed larger and more intensely in the fusion zones than the base metal. Dental metallic implant welding with fiber laser will have higher corrosion resistance in oral use with different temperature and pH environments compared to screw joints.

“…Through microscopic analysis, it was found that high temperatures and low strain rates contributed to increasing the number and depth of dimples. Hu et al [ 28 ] studied the material properties of TC4 titanium alloy and 7075 aluminum alloy under uniaxial tension and compression behavior for typical aerospace alloys. The results showed that the mechanical properties of TC4 were better than those of 7070 aluminum alloy at the same tensile rate.…”

TC4 titanium alloy has excellent comprehensive properties. Due to its light weight, high specific strength, and good corrosion resistance, it is widely used in aerospace, military defense, and other fields. Given that titanium alloy components are often fractured by impact loads during service, studying the fracture behavior and damage mechanism of TC4 titanium alloy is of great significance. In this study, the Johnson–Cook failure model parameters of TC4 titanium alloy were obtained via tensile tests at room temperature. The mechanical behavior of TC4 titanium alloy during the tensile process was determined by simulating the sheet tensile process with the finite element software ABAQUS. The macroscopic and microscopic morphologies of tensile fracture were analyzed to study the deformation mechanism of the TC4 titanium alloy sheet. The results provide a theoretical basis for predicting the fracture behavior of TC4 titanium alloy under tensile stress.
