Thermo-physical behavior of Ti45 Nb titanium alloy was described by nondestructive test

laser pulse

comparative analysis

non-steady method and ejector pins.The results reveal that the Poisson’s ratio of Ti45 Nb alloy is affected slightly by temperature in the range from room temperature to 300 ℃

while the Young’s modulus and shear modulus are decreased rapidly with the increase of temperature.In addition

the thermal diffusivity and thermal conductivity are increased linearly with increasing in temperature.The specific heat is increased in form of the parabola as the temperature increase.The linear thermal expansion curve is increased in form of parabolia before 50℃and increased linearly after 50℃.The instantaneous linear expansion curve is increased linearly with the increase of temperature before100 ℃

and stabilized after 100 ℃.
