α+β型钛合金铸锭在大型轧机中进行初轧然后在α+β相区以>50％的加工率进行热轧,经以下工艺处理后为立方晶型。 热轧以后,炉温最好控制在700℃,并以≤150℃/1h的冷却速度进行缓冷。然后将炉温升 α + β type titanium alloy ingot is subjected to preliminary rolling in a large rolling mill and then hot-rolled in the α + β phase region at a processing rate of> 50%. The α + β titanium alloy ingot is processed into a cubic crystal form by the following process. After hot rolling, the furnace temperature is preferably controlled at 700 ° C and slowly cooled at a cooling rate of ≦ 150 ° C / 1h. Then raise the temperature of the furnace
