The design and experimental research of a mechanical testing apparatus for ultralow temperatures
Abstract In future potential outer-space applications, the temperature of outer space associated with cosmic microwave background radiation is around 2-3 K. A mechanical testing apparatus was designed and manufactured for ultralow temperatures below 4.2 K by liquid helium evacuating refrigeration. The minimum temperature of this apparatus could reach ~1.8 K. Using 304 stainless steel validates the equipment’s test ability at ultralow temperatures below 4.2 K. The results showed that the tensile strength of 304 stainless steel decreased anomalously compared with 4.2 K.
