Popis: | Results of the microstructural modeling of high strain rate isothermal straining of an equiatomic TiNi alloy at different structural conditions using the formulae for strain rate dependencies of dislocation yield limit are presented. Simulations were conducted in the temperature range of 20–300°C. It was shown that the calculated values of the phase and dislocation yield stress in the martensitic and austenitic conditions with a good accuracy correspond to the experimental values. The mechanical behavior of the alloy in the entire investigated temperature range was described using only one pair of constants in strain rate sensitivity of dislocation yield limit. |
