- Abstract
A test machine has been designed for studying the thermomechanical properties of shape-memory-alloy microwires in a temperature range from −190 to +270°C, under mechanical stresses as high as 2000 MPa, and with deformations of up to 50%. The operation of the test machine is based on the method of sample stretching at a variable temperature and a constant load. The elongation of the sample is measured by an optical displacement sensor. The machine was tested on microwires made from the well-known Ni49.8Ti50.2 alloy with the shape memory effect. Using the machine, it is possible to investigate the functional properties of microwire samples with a shape memory effect, which are promising for applications in microsystem engineering, nanotechnology, and medical technology.
