Abstract

The outcome of researches in the field of the methods of brazed joints of dissimilar metals – beryllium and monel silver-based alloy and advanced development model of silver substitution copper-based alloy, developed by Federal State Unitary Enterprise VIAM is the subject of the article. As a matter of course vacuum brazing data was cited as well as vacuum tightness of brazed windows. The researches suggested the possibility of obtaining vacuum-tight brazed joints which provide resistance of thermal cycles simulating welding of beryllium windows into body of pipe and when in operating heating process up to 500°C while brazing alloy 72Ag–28Cu «Cusil», up to 650°С while brazing alloy 92,5Ag–7,5Cu «Sterling Silver» and advanced development model of silver substitution copper-based brazing alloy Cu–Be–Ni. The cause of increasing resistance to the effects of thermal cycles is the result of silver increase and alloy melting point 92,5Ag–7,5Cu, increase of elasticity and heat-absorptive capac
