Abstract: The paper describes main directions of application of pulse magnetic fields in the technological purposes which (directions) are developed at Samara State Aerospace University. In addition to the traditional application of pulse-magnetic processing in blank-stamping production, the paper presents new directions of action of the pulse-magnetic field on the melt, hybrid and combined technologies, changes in properties of metals, special technologies of space, deep-sea, metallurgical and oil purpose. The paper is illustrated with examples of technological application of the pulse-magnetic field in these areas.

Abstract: The paper presents examples of use of the created actuators in engineering - development of various test equipment including that for the needs of space materials-science (devices for measuring of hardness, devices for testing of samples in the conditions of the complex stressed state, testing of assembling joints and others); deforming equipment and devices (presses, dies for cutting - punching, calibration and others); devices used for elimination of consequences of hazard situations.

Abstract: The report provides designs of actuators from the shape memory material-nitinol. It is proposed to use rods, wire, sheets and tape as working elements of the actuators. Special attention is paid to the designs of composite multil-element actuators, working elements of which are connected in parallel or in series. The experimental technique and results of experiments on evaluation of stresses developed by such actuators are given. It is shown that using the composite actuators from thin working elements facilitates control over their heating and cooling.

Abstract: The paper is dedicated to description of the design of special-purpose small-scale pulse-magnetic installations. Recommendations are given on the choice of the element base of energy storages and the high-voltage charging unit for various embodiments. The paper presents main parameters of small-scale pulse capacitors and of current switches of foreign and domestic manufacturers.
