Regularities of the Effect of Process Parameters of SHS-Extrusion on the Structure and Properties of Long-Dimensional Rods from TiB / 30 wt. % Ti Materials

Abstract

In this paper, the effect of the process parameters of the SHS-extrusion method (the delay time before applying pressure, the speed of movement of the press plunger) on the length and quality of extruded cylindrical rods with a diameter of 3 mm, obtained from TiB – 30 wt. % Ti materials, was studied. Their optimal values were determined: the delay time interval was 3–3.5 s, the press plunger speed interval was 40–50 mm/s. Using the results of SEM and XRD, the structural features of the obtained materials were studied, and their texture was determined. The physical and mechanical characteristics of the obtained materials were measured: porosity, hardness, microhardness.
