Phase transitions in shock-loaded titanium at pressures up to 150 GPa

Shock-Wave Properties and Deformation-Induced Structure of Commercial-Purity Titanium

“…The α → ω transformation in VT1-0 titanium begins at 12.2 GPa. This value agrees quite well with the data of [9]. The velocity of the plastic wave increases naturally with increasing shock compression pressure, whereas the time when the plastic wave reaches the target surface decreases regularly.…”

“…A rather large number of works are devoted to the investigation of titanium behavior under shock loading [1][2][3][4][5][6][7][8][9][10][11][12]. A major part of them deals with the investigation of the mechanisms of plastic deformation and fracture under plane shock-wave loading of commercial-purity VT1-0 titanium.…”

“…Impact compression of titanium causes the α → ω transformation. According to different data [6][7][8][9], this transformation occurs at different pressures. The pressure depends on impurities in titanium, in particular, the presence of oxygen [8].…”

“…There are virtually no structural studies of VT1-0 titanium after different loading conditions. The structural data available in the literature are often limited only to X-ray diffraction patterns and optical images [5,9].…”
