Special Issue Information

Dear Colleagues,

As we all know, Ti and Ti-alloys offer a wide range of properties such as high strength, low density, biocompatibility, and good corrosion resistance. These properties are unique advantages for Ti-alloys to be used in various engineering fields, such as the aerospace, biomedical, automotive, and oil and gas industries.

At present, all countries are developing new Ti-alloys with low cost and high performance, and strive to make Ti-alloys enter the civilian industrial field with huge market potential. New applications of Ti-alloys require significant improvements in their physical and mechanical properties, which can be achieved through the use of new technologies (especially laser processing, additive manufacturing, nanotechnology, etc.). Traditionally, alloy design is based on the foundations of physical metallurgy, in particular a deep understanding of structural evolution and structure-property relationships. On the other hand, the rapid development of digital technologies has enabled intelligent engineering and design systems (eg, finite element simulations, neural networks and artificial intelligence, thermodynamic calculations) to play a greater role in the development of advanced materials and technologies.

This Special Issue of Materials aims to present recent original research on the design, mechanical properties and micromechanisms of Ti-alloys. The scope includes microstructures, mechanical properties, deformation mechanisms, and thermodynamics of Ti-alloys.

This work involves studying the effects of applying various designed hot-rolling strategies, using the uniaxial hot compression regimes of the Gleeble 3500 thermo-mechanical simulator on the microstructure, flow behavior, and productivity of Ti-6Al-4V alloy. These strategies were then practically implemented using a rolling mill to produce finished sheets with a thickness of 3 mm. The tensile properties of these finished Ti-6Al-4V sheets were examined, aiming at attaining the optimum rolling strategy conditions that result in upgrading the mechanical performance of the alloy. The undertaken hot-rolling strategies can be divided into two main groups; both comprise applying a total amount of deformation of 75% at a constant strain rate of 0.1 s−1. The first group, isothermal hot rolling regime (IR), includes three strategies and involves applying the total amount of deformation at constant temperatures, i.e., 900, 800, and 750 °C. The second group, non-isothermal hot rolling regime (NIR), includes three strategies and involves partitioning the total amount of deformation into multi-step deformation at variable temperatures in a range of 900–750 °C. The dynamic flow softening is dominant in all IR strategies after the flow stress attains the peak at a low strain value. Then, dynamic flow softening occurs due to the dynamic recrystallization and α phase spheroidization, while a combination of flow softening and hardening takes place on the different passes of the NIR strategies. The designed hot-rolling strategies result in finished sheets with a fine multimodal microstructure that fructifies different mechanical properties that can be employed for different industrial purposes.

The evolution of a local strain of the Ti-6Al-4V alloy subjected to tensile loading was investigated in situ by using the digital image correlation technique. The results show that some local strain concentration areas have already appeared in the elastic deformation stage, which then connected and became concentrated in the gauge region when the specimen yielded. The strain compatibility of grains in the macroscopic region is kept constant. The deformation process is further divided into six parts based on the development of the maximum strain gradient, and the strain compatibility of each stage of the alloy is summarized and analyzed. The quasi-in situ experiment reveals that the primary α(αp) grains undertake the main deformation at the micro-scale. Full article
