摘要：

Design details and performance of a combined cryostat and oven for an Instron TT-CM universal testing machine are described. The cryostat is suitable for tensile testing in the range 83 to 473 degrees K and has a test chamber 5.5 in. x 5.5 in. and 20 in. deep which could be used for testing specimens 7 in. wide. Special attention is drawn to the ease of specimen insertion which may be performed while the cryostat is cold. The temperature within the test chamber is controlled, by admitting dry air, to +/- 1 degrees C of any desired test temperature for periods of at least 20 min. A specimen transfer device is also described for transferring a pretreated specimen at -26 degrees C to the cryostat with a temperature rise of less than 1 degrees C. The transfer device provides a method of rapid specimen insertion once the cryostat is cold.
