“…For example, Zhang et al [11] examined the effect of cold-rolling deformation and aging treatment on the mechanical properties of Cu-0.45Cr-0.14Ti (wt%) alloys and concluded that the time required for the alloys to reach maximum strength is shorter as the degree of deformation increases. A similar conclusion, that higher strength and a shorter time to reach maximum strength was obtained with the greater deformation after aging treatment on Ti-Nb-Zr alloy, was drawn by He et al [12]. Sadeghi-Nezhad et al [13] conducted a study on AA2024 alloy, whereby they reached the conclusion that the rolling and aging treatment possessed the capability to augment the mechanical properties of the alloy.…”

A systematical exploration of the effect of aging time on the microstructure and mechanical properties of cold-rolled Ni-W-Co-Ta medium–heavy alloy with 90% thickness reduction at the aging temperature of 700 °C was performed. The results demonstrate that the volume fraction of the precipitation (Ni4W), which persists under various aging times, increases from 13.7% (2 h) to 28.7% (32 h) with the extension of aging time. Meanwhile, the microstructure after aging treatment is still dominated by dislocation entanglement and dislocation walls, although the degree of lattice distortion and dislocation density attributed to heavy deformation decreases. The maximum tensile strength, yield strength, and microhardness (2286 MPa, 1989 MPa, 766 HV) of the cold-rolled Ni-W-Co-Ta medium–heavy alloy under the 16 h aging treatment at 700 °C are reached, respectively. The ductile–brittle mixed fracture morphology is maintained in the fracture morphology of the medium–heavy alloy before and after aging treatment.

“…Increasing the aging temperature gradually replaced the ω phase with α phase, changing its morphology and size. Feng He et al 144 compared solution treatment and aging, finding that aging followed by cold rolling exhibited high strength. Cold deformation promoted α phase precipitation due to the inhibition of ω phase nucleation by dislocations and grain boundaries.…”

Over the past few years, significant research and development in the manufacturing industry related to the medical field has been done. The aim has been to improve existing biomaterials and bioimplants by exploring new methods and strategies. Beta titanium alloys, known for their exceptional strength-to-modulus ratio, corrosion resistance, biocompatibility, and ease of shaping, are expected to play a crucial role in manufacturing the next generation of biomedical equipment. To meet the specific requirements of human bone, researchers have employed key techniques like compositional design and thermomechanical processing routes to advance biomaterial development. These materials find extensive applications in orthopedic, orthodontic, and cardiovascular biomedical implants. Several studies have shown that precise material composition, with appropriate heat treatment and suitable mechanical approaches, can yield the desired mechanical properties for bone implants. In this review article, we explore the evolution of alloys at different stages, with a particular focus on their preparation for use in biomedical implants. The primary focus is on designing low-modulus β Ti alloy compositions and employing processing techniques to achieve high strength while maintaining a low young modulus suitable for biomedical applications.

“…b titanium alloys exhibit desirable characteristics in the eld of biomedical engineering, including a low elastic modulus, high elastic strain allowance, and favorable biocompatibility. [1][2][3] These attributes make them attractive for various applications such as dental implants, cranial bone repair implants, heart valves, and spinal xation devices. [4][5][6] However, the mismatch in elastic modulus between the alloy and bone tissue, [7][8][9] as well as its biologically inert surface properties, 10,11 impose limitations on its wider usage.…”
