1. The long-term strength of molybdenum alloys subjected to cyclic changes of temperature is considerably lower than the long-term strength at constant temperature. The long-term strength of each alloy decreases in a certain temperature range if the

1. For alloys in the recrystallized condition with an increase in rhenium content from 7 to 36% there is an increase in strength and ductility at normal temperature. For metal in the worked condition with an increase in ultimate strength the ductilit

1. Melting of Mo−W alloys with >20% W requires more power than melting of unalloyed molybdenum or tungsten. The power required is highest for melting alloys with 80–85% W. 2. Alloys with 17–85% W have considerably finer grains as-cast than unal

1. The alloy of Mo+30% W is susceptible to hot brittleness at 1400–1800°C. 2. Varying the tungsten content from 28 to 35% has little effect on the susceptibility to hot brittleness. Raising the carbon content from 0.002 to 0.007% sharply reduces t

An attempt was made to determine an indirect criterion of the plasticity of the weld joint of molybdenum alloys revealed in inspection of the properties of the welded sheets themselves. The possibility of use as such a criterion of the parameters of

1. Inverse pole figures were plotted to study the texture of the weld seam and transition zone as well as the original sheet of low-alloy molybdenum alloy TsM-10. To a certain extent the weld metal “inherits” the texture of the original metal. If

1. Addition of rhenium in quantities from 0.5 to 36% into molybdenum does not result in monotonic reduction of the metal cold brittleness threshold in its cast condition (Tbu), as this is usually suggested in technical literature [5, 6, 9]. 2. In int

1. The temperature dependence of the mechanical properties is correlated with structural transformations that occur during high-temperature testing. The extremal properties (highest strength and lowest ductility, and also lowest resistivity) depend o
