chamber and "sub zero" systems lead towards an oxidation free and low distortion vacuum heat treatment for a broad range of parts and materials. Short and energy saving processes guarantee a high economic efficiency and environmental compatibility.The "sub zero" system which is integrated into the standard vacuum furnace achieves a heat treatment result with a high conversion of retained austenite......

ratio. 2) Temperature distribution totally depends upon the pressure distribution into OHP. Repeated pressure fluctuation reduces heat flow resistance, and high evaporative temperature and the optimum filling ratio cause high rate of pressure fluctuation. Nomenclature References [1] AKACHI H. Structure of a heat pipe. US Patent No. 4921041 [P]. 1990. [2] ZHANG Y W, FAGHRI A. Advances......
