Abstract
A fluidized bed of solid particulate material cools a heated workpiece through a temperature range critical to strength property determination. Upon immersion into the fluidized bed container the bed is allowed to collapse around the workpiece forming a universal fixture which firmly supports the workpiece for the remainder of the cooling, allowing cooling to be completed at a slower rate to prevent or minimize distortion caused from differential thermal contractions.
