The utility model is just achieved through the following technical solutions.
A kind of molybdenum and molybdenum alloy tube, the tensile testing device of bar, the equipment include universal testing machine, are arranged on omnipotent
High temperature furnace between the upper and lower crossbeam of testing machine, the extensometer in stove, the temperature being connected with high temperature furnace are stretched into from the high temperature furnace sidewall
Degree controller, two structure identical upper fixtures and lower clamp, the upper fixture are fixed on the entablature of universal testing machine, institute
State lower clamp to be fixed on the sill of universal testing machine, the bare terminal end of two fixture stretches into high temperature furnace and relative
Set；Characterized in that, the equipment also includes inert atmosphere protection device, the inert atmosphere protection device is arranged on omnipotent
The side of testing machine, the escaping pipe of the inert atmosphere protection device is two segment pipes, and the two segment pipes docking is fixed, wherein
One segment pipe is metal tube, and the metal tube is stretched into high temperature furnace from high temperature furnace bottom.
According to above-mentioned equipment, it is characterised in that the inert atmosphere protection device is for argon device.
