Elastic characterization of platinum/rhodium alloy at high temperature by combined laser heating and laser ultrasonic techniques.
We demonstrate an innovative pump-probe technique combined with laser heating to determine the velocity of a surface Rayleigh wave at high temperature. Laser ultrasonics in a point-source-point-receiver configuration was combined with laser heating to evaluate the elastic properties of micron size specimens. The measurements of the velocity of the surface Rayleigh wave (SRW) were conducted at 1070K.
