“…Cylindrical specimens with a diameter of 6±0.1 mm and a height of 9±0.1 mm were made from the investigated metal matrix composite (MMC). We compressed these specimens by a plastometric unit at a temperature of 500 °C according to the technique described in detail in [2]. The specimens were heated up to the test temperature for 1 hour.…”

The paper studies the effect of strain rate on the formation of grains and low-angle boundaries in an aluminum matrix composite based on the 1950 alloy (analogous to the AA7075 alloy) with 10 vol% SiC. The deformation of the metal matrix composite, produced by a powder technique, is investigated at a temperature of 500 °C. The specimens are investigated by electron backscatter diffraction before and after deformation at strain rates ranging from 0.1 to 5.5 s -1 . It has been established that continuous dynamic recrystallization occurs in the composite at 500 °C in the whole strain rate range considered. The recrystallization is followed by a decrease in the average grain diameter and an increase in the density of the low-angle boundaries with increasing strain rate.

“…The value must be known to assess the heterogeneity of strength and mechanical properties in the volume of the metal, to calculate the power parameters of the process, which determine the stable flow of the metal deformation process. Many works are devoted to the development of adequate mathematical models for strain resistance calculations [1][2][3][4][5][6][7][8][9][10]. Most of the studies based on the plastometer tests, which allow to consider the influence of degree , rate and temperature of deformation on .…”
