The influence of solid solution treatments on the dissolution of carbides precipitates, the grain size, and the hardness of high strength low expansion alloy were investigated through XRD analysis, microstructure observations, and theoretical computation. It was seen that most primary Mo-2 C type carbide band dissolved in a temperature range of 1 100 - 1 150 degrees C. When the temperature was over 1 200 degrees C, the grain size increased remarkably, which led to the reduction of hardness.
