Chapter 3HEAs’ Stability

Gromov, V. E.; Konovalov, S. V.; Ivanov, Yu. F.; Osintsev, K. A.

Pages: 53 –57

[In this chapter, the problem of stability or metastability of HEAs was analysed. This problem is one of the main ones in analysing the influence of temperature on a whole range of properties. The factors determining the structure and stability of multicomponent disordered solid solutions are...

Chapter 4Prospects of High-Entropy Alloys Application

Gromov, V. E.; Konovalov, S. V.; Ivanov, Yu. F.; Osintsev, K. A.

Pages: 59 –62

[In this chapter, the prospects of high-entropy alloys’ application were observed. There are several the most promising spheres of applications of HEAs such as nuclear power industry, as they have high resistance to radiation, as refractory (due to high strength at elevated temperatures and...

Chapter 6High-Entropy Alloys of AlCoCrFeNi-System

Gromov, V. E.; Konovalov, S. V.; Ivanov, Yu. F.; Osintsev, K. A.

Pages: 79 –110

[In this chapter, the high-entropy alloy of Al-Co-Cr-Fe-Ni system was manufactured by the wire-arc additive manufacturing technology and irradiated with high-intensity electron beams. The as-manufactured alloy has high microhardness but a brittle structure. The compression tests have shown that...
