Heat Effect in the Metalls During Electropulse Treatment DOI: 10.22184/2499-9407.2023.33.4.34.41
The thermal effect of pulse current in alloys for various purposes: shape memory of Ti49,2Ni50,8, and structural D16 and VT6 has been studied. It was found that the thermal effect during pulse current treatment depends not only on the electrical and heat conducting properties of alloys, but also decreases with increasing dispersion and level of internal microstructure stresses. The heating under the modes similar to the current modes during rolling of the studied alloys has been experimentally modeled.

Kinematic Analysis of a Modified Rotopod Mechanism with Four Kinematic Chains DOI: 10.22184/2499-9407.2023.33.4.70.76
An algorithm for solving the problem of determining the working area of a modified rotopod mechanism with four kinematic chains, the output link of which has six degrees of freedom, is presented. It is shown, that the considered spatial mechanism can find application for robotic complexes for processing of complex-shaped parts and additive technologies, as well as in measuring metrological systems.
