Special Issue Information
Dear Colleagues,
Biomaterials are used for diagnosing, treating, repairing or replacing damaged tissues and further enhancing the function of organisms, thus improving the quality of life of the patient. Bone implant materials are an important part of biomedical materials, and about 70% - 80% of implants are made of biomedical alloys. The demand for biomedical alloys is rapidly increasing as the world population is getting older. The most representative biomedical alloys are stainless steels, cobalt (Co)-chromium (Cr) alloys, and titanium (Ti) and its alloys for their applications in artificial hip joints, bone plates, spinal fixation rods, cardiovascular applications (stents), catheters, MRI, dental applications, etc. Among these, Ti alloys exhibit the highest biocompatibility, corrosion resistance, and specific strength (ratio of tensile strength to density). Co–Cr alloys exhibit the highest wear resistance and relatively higher strength compared with stainless steels and Ti alloys. Stainless steels generally exhibit higher ductility and cyclic twist strength compared with Co–Cr and Ti alloys. Stiffness is greatest for Co–Cr alloys, while it is the lowest for Ti alloys. Other metallic biomaterials, such as magnesium (Mg) alloys, iron (Fe), tantalum (Ta), and niobium (Nb) are also important, although their share of this field is small. These representative biomedical alloys can be processed via conventional melting and alloying as well as 3D additive manufacturing which enables complex implant shapes for specific applications.
This Special Issue will compile the recent developments in materials for biomedical applications. The articles presented in this Special Issue will cover various topics, ranging from but not limited to the microstructural design of alloys, their processing, detailed characterization, mechanical properties, corrosion resistance, and, biocompatibility and functionality.
We invite you to contribute to this Special Issue by submitting papers on your best research activities.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
