Researchers studied a type of alloy based on tungsten, chromium and yttrium. This material’s high resistance to deuterium makes it promising for use in fusion reactors.
Currently, tungsten is used as material for the walls of such reactors due to its high temperature stability. However, at higher heat and particle fluxes, as is the case in plans for future reactors, tungsten may degrade due to hydrogen absorption.
The experimental alloy developed by scientists passed stringent tests and showed good results. It absorbs less hydrogen, which makes it more durable under operating conditions of the thermonuclear reactor, the press service noted.
