Grahic Jump Location
Experimental correlation and least-square fit of the flow or fracture stress, Yn, of hard alpha as a function of nitrogen content. The least-square fit applies to the fracture stress only.
Grahic Jump Location
Semi-log plot of flow, Y, or fracture stress, Yi, as a function of pressure, P=σkk/3; both Yi and P are normalized by the uniaxial compression flow or fracture stress, Yn
Grahic Jump Location
Engineering stress-strain curves of hard alpha Ti with various nitrogen contents tested by plane strain compression at a strain rate of 0.01 s−1
Grahic Jump Location
Comparison of the calculated fracture stress of the intact materials and the “flow” stress of the failed material
Grahic Jump Location
Calculated and measured flow stress of hard alpha Ti as a function of nitrogen contents for two strain rates
Grahic Jump Location
Comparison of calculated and measured true stress-strain curves of hard alpha Ti with 2 wt. percent N for two strain rates
Grahic Jump Location
Measured true-stress-strain curves compared to model calculations for two strain rates. The experimental data (GE data) were corrected for adiabatic heating.
