摘要	TITANIUM ALLOY BLANKS OR THE LIKE ARE SUCCESSIVELY COATED WITH A HIGH TEMPERATURE LUBRICANT, PREHEATED IN A PREHEAT OVEN TO A FORMING TEMPERATURE (ABOUT 1000-1500* F.), PRECISION FORMED INTO A DESIRED SHAPE IN A PRESS WHICH INCLUDES INDUCTIVELY HEATED FORMING TOOLS, SERVING TO MAINTAIN THE METAL AT THE FORMING TEMPERATURE THROUGHOUT THE FORMING OPERATION, AND SLOWLY COOLED, FIRST IN A POSTHEAT OVEN DOWN TO A LOWER ELEVATED TEMPERATURE (E.G. ABOUT 600* F.) AND THEN UNDER COVER OF AN ASBESTOS BLANKET DOWN TO AMBIENT TEMPERATURE. THE HEAT FORMING TOOLS INCLUDE A FIXED DIE, A MOVABLE DIE AND A MOVABLE CLAMPING PAD. THE MOVABLE TOOLS ARE MOUNTED FOR PRECISION MOVEMENT BY LEADER PINS AND BUSHINGS. INSULATION AND WATER JACKETS ARE INTERPOSED BETWEEN THE HEATED TOOLS AND THE LEADER PINS AND BUSHINGS TO PREVENT HARMFUL HEATING OF THE LATTER. THE FORMING TOOLS COMPRISE WATER COOLED TUBULAR CONDUCTORS EMBEDDED IN INSULATIVE MATERIAL WHICH IN TURN IS EMBEDDED IN FERROMAGNETIC CORES, AND DIE PARTS OF LONG LIFE METALS ON WHICH THE FORMING SUFACES ARE MACHINED.
