Abstract
Based on the rheological approach, the paper established the regularities of cold uniaxial deformation of powder materials consisting of Ti‒B and Ti‒Al‒Nb‒Mo‒B layers. The Ti‒B layer was chosen with the following composition: TiB‒30 wt.% Ti (TiB), intermetallic layer ― 51,85Ti‒43Al‒4Nb‒1Mo‒0,15B at. %. 5 types of charge blanks with diameters of 12 and 25 mm were investigated (layers were selected, vol. %: 100 TiB, 100 TNM, 70 TiB / 30 TNM, 50 TiB / 50 TNM, 30 TiB / 70 TNM). Experimental rheological dependences of stress-strain are built for each type of powder blanks. On the obtained dependences, three areas of compaction are distinguished. The effect of the billet diameter on the degree of deformation and the stresses that arise in powder billets is shown. For a workpiece consisting only of intermetallic compounds, an irregular compaction mode was found at stresses above 100 MPa.
