The development of methods for improving heat transfer in a metal hydride tank is an important task. At present, two main methods have been proposed to solve the problem of heat transfer inside the metal hydride bed - this is the use of a heat exchanger or the use of additives that increase thermal conductivity. This article is devoted to possible options for improving heat transfer inside the metal-hydrides cylinder using efficient heat exchangers or by adding materials with high thermal conductivity to the hydride-forming metal. As confirmation of the possibility of improving thermal conductivity by adding material with high thermal conductivity, the data obtained in the study of the composite MgH2 + CNT are given.

In this study, the effect of additional heat treatment on the microstructure and mechanical properties of the titanium Ti-6Al-4V alloy produced by the method of electron beam melting was studied. It has been established that additional heat treatment of samples allows reducing the friction coefficient and decreasing internal stresses in the material. At the same time, a decrease in microhardness, as well as the strength and plastic characteristics of EBM Ti-6Al-4V alloy, is observed. Simultaneously, heat treatment leads to a reduction in the rate of hydrogen accumulation by EBM Ti-6Al-4V alloy during saturation from a gaseous medium. [ABSTRACT FROM AUTHOR]
