Abstract

Abstract

An in-situ temperature loading system was designed. It can control the samples temperature from 25 ℃ to 800 ℃, and the temperature controller applied improved Dahlin algorithm to inhibit temperature overshoot. The system was tested with neutron beam on the residual stress neutron diffractometer. The result shows that the structure suits for neutron diffraction experiment, and the temperature keeps not higher than the target during the ascending period, and the precision is 1 ℃ during the stable period, which meets temperature loading requirements for shape memory materials.
