“…The same procedure was repeated for the third cycle. The results from [66] showed that the amount of the alloying elements increases after each cycle. After the second one, an intermetallic phase in the system of Ti-Al-Nb, namely body-centered cubic-B2 (BCC-B2) Ti 2 AlNb was formed.…”

“…As already mentioned, the alloying of pure Ti substrate with Al and Nb by using a beam current of 25 mA led to a successful introduction of the alloying elements into the base material, but intermetallic phases within the discussed ternary system have not been observed. The same authors continued their research [66] by realizing a cyclic technique for the incorporation of the alloying elements into the Ti matrix. A scheme of the technique is presented in Figure 12.…”

During the last decades, electron-beam treatment technologies (EBTT) have been widely used for surface modification of metals and alloys. The EBT methods are known as accurate and efficient. They have many advantages in comparison with the conventional techniques, such as very short technological process time, uniform distribution of the energy of the electron beam, which allows a precise control of the beam parameters and formed structure and properties of the materials, etc. Moreover, electron-beam treatment technologies are a part of the additive techniques, which are known as modern methods for manufacturing of new materials with unique functional properties. Currently, modern trends in the surface treatment of metals and alloys are based on the combination of electron-beam technologies with other methods, such as thin film deposition, plasma nitriding, etc. This approach results in a significant improvement in the surface properties of the materials which opens new potential applications and can involve them into new industrial fields. This paper aims to summarize the topics related to the manufacturing and surface treatment of metals and alloys by means of electron-beam technologies. Based on a literature review, the development and growth of EBT are considered in details. The benefits of these technologies—as well as their combination with other methods—are extensively discussed.
