“…Studying an HEA with the same composition (TiNbZrHfTa) of one of the alloys studied by Gurel et al [25], the works of Yang et al [45] and Berger et al [19] confirmed the single-phase BCC microstructure. However, the elastic modulus value was much lower than that found by Gurel et al [25]: 66 GPa [19]. For this alloy, a tensile strength of 1050 MPa was obtained.…”

“…The review on high-entropy alloys as biomaterials, with the intention of using them for the varied medical applications (implants, stents, structures, and coatings of conventional alloys), shows that the vast majority have a BCC structure. Generally, refractory elements with Ta, W, Nb, Mo, or V are BCC-phase stabilizers [18,19,37].…”

“…Since then, this term has been applied for multiprincipal element alloys that have been considered for applications in the biomedical field. The challenge is to overcome the limitations of conventional alloys (cp-Ti, Ti6Al4V, 316L, and CoCrMo alloys), and some promising results were reported concerning superior or similar corrosion resistance and implant degradation in a physiological environment [12][13][14], mechanical performance combined with biocompatibility [14][15][16][17][18][19][20], ion release [21,22], magnetic susceptibility [23,24], wear resistance [12,25], and bacterial infection [19].…”

Due to its great amount of microstructure and property possibilities as well as its high thermodynamic stability and superior mechanical performance, the new class of material known as high-entropy alloys (HEAs) has aroused great interest in the research community over the last two decades. Recent works have investigated the potential for applying this material in several strategical conditions such as high temperature structural devices, hydrogen storage, and biological environments. Concerning the biomedical field, several papers have been recently published with the aim of overcoming the limitations of conventional alloys, such as corrosion, fracture, incompatibility with bone tissue, and bacterial infection. Due to the low number of available literature reviews, the aim of the present work is to consolidate the information related to high-entropy alloys developed for biomedical applications (bioHEAs), mainly focused on their microstructure, mechanical performance, and biocompatibility. Topics such as phases, microstructure, constituent elements, and their effect on microstructure and biocompatibility, hardness, elastic modulus, polarization resistance, and corrosion potential are presented and discussed. The works indicate that HEAs have high potential to act as candidates for complementing the materials available for biomedical applications.

“…245–248 Generally, at least five main elements share the equiatomic position in HEO and different structures, such as spinel, perovskite structure, and single-phase rock salt, which coexist in the crystal. 249–251 Despite all the above-mentioned advantages, the understanding of the structural chemistry in HEOs is still unclear, which imposes significant limitations on the design of new performance-oriented materials.…”

“…The material property requirement of these materials being used as biomaterials ranges from biocompatibility [33,139,146,[149][150][151][152][153][154][155][156][157][158][159][160], good mechanical, corrosion, and physical properties closer to the part of the human bone or tissue being replaced [113,139,140,146,[155][156][157][161][162][163][164][165][166][167][168][169][170][171][172][173][174]. There should also be some level of porosity for good cell attachment and great connectivity while interacting with the human cell and to ensure tissue growth and soft tissues such as cartilage, tendons, vasculature, and the skin [175][176][177][181][182][183][184][185][186].…”

Global perspective and African outlook on additive manufacturing research − an overview

et al. 2022

View full text Add to dashboard Cite

Additive manufacturing (AM) technologies and advances made globally in medicine, construction, aerospace, and energy sectors are discussed. The paper further explores the current state of AM innovation and development landscape in Africa as a late comer to this area of smart manufacturing. Peer-reviewed and published literature were retrieved from Scopus database from 2005 to 2021 and analysed. In Africa, out of 500 published articles, South Africa has the highest research throughput, whereas about two-thirds of the continent is not actively participating in this burgeoning field. The main AM techniques most widely used are selective laser melting, fused deposition modelling, and direct energy deposition. Globally, there is an interplay of computational (machine learning and mechanistic models) and experimental approaches to understanding the physical metallurgy of AM techniques and processes. Though this trend is consistent with global practices, Africa lags the world in AM technologies, a niche that could leapfrog the manufacturing sector. Thus, Africa need to foster collaborative partnership within and globally to become an active global player in this industry.
