“…Titanium and its alloys as lightweight metals of high relative mechanical strength and fatigue limit, corrosion resistance, and outstanding biocompatibility at moderate costs are found in different branches of modern industry, as materials for aircraft [1,2], marine applications [3], military equipment, industrial-technological systems, automotive parts, farming fitting, sporting goods, and biomedical engineering [4,5]. In particular, in medicine, titanium-based alloys are mostly applied to fabricate long-term implants, or their parts, such as the dental, hip joint, knee, and other implants, load-bearing applications [6,7]. The most important value of these materials for medicine is in their high strengthto-density ratio, remarkable corrosion resistance, small elastic modulus compared to various metallic biomaterials, and excellent biocompatibility.…”

Surface modification of the titanium and its alloys used in implantology with a long-pulse laser can change the surface topography, but it also leads to changes in the stress sign and magnitude in the resulting subsurface layer. The presented research was aimed at evaluating the state of stress after laser remelting with the Nd:YAG laser of preetched titanium alloys Ti6Al4V and Ti13Nb13Zr and pure titanium.The obtained surface layers were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), optical profilography, and nanoindentation studies. Based on the results obtained after the nanoindentation tests, the character of the stresses generated in the melted layers was calculated and determined. Laser processing resulted in surface layer thicknesses between 191-320 µm and surface roughness Ra between 2.89-5.40 µm. Laser processing caused increasing hardness, and its highest value was observed for the titanium alloy Ti13Nb13Zr -5.18 GPa.The tensile stressesappeared following laser treatment andincreased with elevating laser power up to the highest value for titanium.

After plastic deformation, metals and alloys will be in a thermodynamically unstable high free en-ergy state with a tendency to spontaneously return to a low free energy state. Understanding the laws of occurrence and development of these processes is of great significance in improving and controlling the microstructure and properties of TB18 titanium alloy. In this paper, the recrystalli-sation kinetics is investigated based on the Johnson-Mehl-Avrami equation, and a kinetic model for the grain growth of solid solution TB18 alloy undergoing predeformation at different solid solution temperatures and different solid solution times has been established by combining the Arrhenius formula and Beck's equation to derive a prediction model for the grain size that includes three types of parameters, namely, T, t, and ε, during the solid solution process. Using simulation soft-ware(Deform) based on finite element analysis to simulate the grain size of forging heat treatment, validate the grown-up model, and analyse the deformation of each part of the forging and the grain size deviation of its corresponding position. The results show that the deviation of grain size pre-dicted by the TB18 grain size model for the forging after heat treatment is less than 10%. Overall, the size prediction model of the grain growth has been proven to be accurate and usable.
