High entropy alloys (HEAs) earned the attention of the scientific community since their discovery in the year 2004, while the progress in this field has been realized since the year 2010 when a drastic increase in demand for HEAs was observed due to their unique characteristics and ability to form several compositions. As universally acknowledged, the immense potential in compositions, microstructures, and properties has sparked a great interest in this field. Researchers primarily focused on equiatomic HEAs, but the paradigm eventually shifted to non-equiatomic alloys. As the research progressed, four core effects were identified as the most important aspects in enabling the distinct characteristics. Mechanical alloying (MA), followed by the sintering approach, has piqued the interest of all researchers focusing on HEA processing. Accordingly, the main objective of this review is to critically discuss mechanically alloyed HEAs in the view of mechanical properties, tribological behavior, and functional properties. Furthermore, the predominant challenges and their conceivable prospects are also deliberated that offer novelty to this review article.

“…In the study of the α phase, it was found that the high dislocation density and a large number of non-equilibrium grain boundaries/sub-grain boundaries generated during the ECAP process, which provide a good nucleation site for α-phase precipitation, and the ultrafine equiaxed α grains were formed in the β matrix. Moreover, vacancies and non-equilibrium grain boundaries in the microstructure enhance atomic diffusivity and accelerate the formation of the α-phase [111]. Dyakonov et al argued that the evolution of the primary α phase was driven by continuous dynamic recrystallization [112].…”

Applications of a metallic material highly depend on its mechanical properties, which greatly depend on the material’s grain sizes. Reducing grain sizes by severe plastic deformation is one of the efficient approaches to enhance the mechanical properties of a metallic material. In this paper, severe plastic deformation of equal channel angular pressing (ECAP) will be reviewed to illustrate its effects on the grain refinement of some common metallic materials such as titanium alloys, aluminum alloys, and magnesium alloys. In the ECAP process, the materials can be processed severely and repeatedly in a designed ECAP mold to accumulate a large amount of plastic strain. Ultrafine grains with diameters of submicron meters or even nanometers can be achieved through severe plastic deformation of the ECAP. In detail, this paper will give state-of-the-art details about the influences of ECAP processing parameters such as passes, temperature, and routes on the evolution of the microstructure of metallic materials. The evolution of grain sizes, grain boundaries, and phases of different metallic materials during the ECAP process are also analyzed. Besides, the plastic deformation mechanism during the ECAP process is discussed from the perspectives of dislocation slipping and twinning.

Titanyum alaşımları sahip oldukları üstün mekanik özellikler sebebiyle havacılık ve medikal endüstrileri başta olmak üzere çok sayıda sektörde kullanılmaktadır. Ancak titanyum malzemelerin üretim maliyetlerinin yüksekliği ve sınırlı şekillendirilebilirlikleri bir dezavantaj olarak kullanım alanlarını sınırlamaktadır. Titanyum alaşımlarının şekillendirilebilirlik kabiliyetlerini artırmak için faz durumuna ve alaşım oranına göre uygun sıcaklık ve süreyle malzemeye ya da şekillendirme kalıbına müdahale etmek gerekebilmektedir. Bu çalışmada; titanyum alaşımlarının şekillendirilebilirlik kabiliyetlerini artırmak için yapılan çalışmalar, kullanılan ekipmanlar ve geliştirilen yöntemler ile sıcaklığın alaşımın mikroyapısına etkileri farklı faz gruplarına göre derlenmiştir.
