A description is given of a device which uses the thermal expansion of a metal rod to bend at a constant strain rate alkali halide single crystals for use in piezoelectric and internal friction studies. Plastic strains of approximately 10<sup>−2</sup> have been produced in potassium chloride and lithium fluoride at strain rates of about 10<sup>−7</sup> s<sup>−1</sup>.
