核能工厂用的锆合金结构件在热轧后、冷加工前,在α+β区进行860～1000℃的固溶处理,最好在惰性气氛中处理。固溶处理后的合金以150～400℃/s的速率快速冷却到700℃以下,以便使合金的晶体结构保持为α+β相。锆合金用于原子能工 Zirconium alloy structural parts for nuclear power plant are subjected to a solution treatment in the α + β zone at 860 to 1000 ° C after hot rolling and before cold working, preferably under an inert atmosphere. The solution treated alloy is rapidly cooled to below 700 ° C at a rate of 150 to 400 ° C / s in order to maintain the crystal structure of the alloy as the α + β phase.
