“…In addition to metal forming processing or turning, other original technological solutions using pulsed current are known. These include cutting [ 105 , 106 , 107 ], pressure welding of metals [ 108 ], equal-channel angular pressing [ 109 ], and the possibility of structural refinement [ 3 ]. We also note the recently published review of the directions of EPE application [ 6 ] and the specific application of deep drawing technology using electric current on the example of an Al–Mg alloy ( Figure 16 ) [ 110 ].…”

A review of studies on the electroplastic effect on the deformation process in various conductive materials and alloys for the last decade has been carried out. Aspects, such as the mode and regimes of electric current, the practical methods of its introduction into materials with different deformation schemes, features of deformation behavior accompanied by a pulsed current of different materials, structural changes caused by the combined action of deformation and current, the influence of structural features on the electroplastic effect, changes in the physical, mechanical, and technological properties of materials subjected to plastic deformation under current, possible mechanisms and methods of physical and computer modeling of the electroplastic effect, and potential and practical applications of the electroplastic effect are considered. The growing research interest in the manifestation of the electroplastic effect in such new modern materials as shape-memory alloys and ultrafine-grained and nanostructured alloys is shown. Various methods of modeling the mechanisms of electroplasticity, especially at the microlevel, are becoming the most realistic approach for the prediction of the deformation behavior and physical and mechanical properties of various materials. Original examples of the practical application of electropulse methods in the processes of drawing, microstamping, and others are given.

In this paper, we design DeLottery, a decentralized lottery and gambling system based on block chain technology and smart contracts. Lottery is a classical form of entertainment and charity for centuries. Facing the bottleneck of the combination between lottery and information technology, we use smart contracts and blockchain in decentralized, intelligent, and secure systems for lottery industries. Moreover, we are inspired by the algorithm of RANDAO, an outstanding way of random number generation in blockchain scenario. The components and the functions of the novel system are described in details. We implement DeLottery in a blockchain network and show functioning procedure and security of the proposed lottery system.

The mechanical properties of metals change temporarily or permanently under the influence of a high density electric current in the deformation zone. This phenomenon is called electroplasticity, and its use makes it possible to intensify the process of pressure treatment of electrically conductive materials, including those that are difficult to machine using existing technologies. By now, there is no established point of view on the physical nature of the manifestation of electroplasticity, although this effect itself has already found practical application. The electrical plasticity of metals and their alloys was studied under various loading conditions, including tensile, compression, and bending tests. The article analyzes the theoretical mechanisms of the occurrence of electroplasticity described in scientific publications, the results of studies of the electroplastic properties of various metals or metal alloys, and recommendations for the practical application of the electroplastic effect.
