A cryostat was constructed and installed in a MTS 810 servohydraulic testing machine for studying fatigue properties associated with pseudoelastic cycling of shape memory alloys down to liquid‐nitrogen temperatures. Special attention was focused on eliminating temperature fluctuations during the fatigue experiments. In order to perform long time fatigue tests, an automatic controlled system which supplies the cryostat with liquid nitrogen was developed and described in detail.
