About this Research Topic
Hexagonal close-packed (HCP) metals and alloys, which include titanium, zirconium, magnesium, etc., are extensively used in a variety of industrial sectors. For example, titanium and titanium alloys are widely employed in aerospace, marine, chemical engineering and biomedicine industries due to their high specific strength, high corrosion resistance and high biocompatibility; zirconium and zirconium alloys are used in the nuclear industry owing to high resistance to waterside corrosion and a low absorption cross section for thermal neutrons; magnesium and magnesium alloys receive significant attention in automobile, aerospace, and computer industries because of their low density, desirable mechanical property and thermal conductivity.
Relative to face-centered cubic (FCC) and body-centered cubic (BCC) metals and alloys, HCP metals and alloys show some distinct characteristics, such as anisotropic microstructure, few slip systems, and deformation twinning due to their HCP crystal lattice structures. As such, there is an increased need to improve the understanding of the relationships among the processing procedures, microstructures and resultant properties. Furthermore, due to various surface property requirements, surface processes are frequently applied to HCP metals and alloys. Research into these various surface-modification methods is still ongoing, as there are many unsolved challenges.
This Research Topic aims to highlight recent advances related to the processing, microstructure and properties for hexagonal close-packed metals and alloys. We wish to collect a series of high-quality work on this topic to better understand the relevant mechanisms and facilitate engineering applications. We welcome contributions addressing all aspects of HCP metals and alloys toward tackling the above considerations. As such, we welcome submissions in the form of Original Research, (Mini) Review and Perspective articles, including but not limited to the following themes:
