the sound path in solid with temperature graident

According to Snell's law, the sound wave will refract if it incidents (not perpendicularly) onto a interface of different material with different sound velocity. And normally the sound velocity of the solid is dependent on the temperature. so, the sound path is not a line but a curve when the ultrasonic wave enter (not perpendicularly) into the solid with temperature gradient. is this conclusion right? where can I find the detailed data about sound velocity dependent on temperature for metals, such as aluminum and steel?

SONOAIR - air-coupled Phased Array Ultrasonic Inspection System

For highly attenuating materials, the performance of the system is critical. The ultrasonic sensors,
...
the scanning area and the system settings should be flexibly adapted to the test task and the material. These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers.
