為了揭示變形程度和變形溫度對β預制坯針狀組織的影響規律，在800、820、840和860 ℃這4個不同溫度以及20%、40%、60%和80%這4個不同應變量進行小餅等溫壓縮試驗。

為了揭示變形程度和變形溫度對β預制坯針狀組織的影響規律，在800、820、840和860 ℃這4個不同溫度以及20%、40%、60%和80%這4個不同應變量進行小餅等溫壓縮試驗。研究結果表明：變形程度是影響TC17鈦合金球化的主要因素。在變形量為40%~60%時，片狀α組織受到剪切作用并發生動態再結晶；當變形量大于60%時，組織發生有效球化。在800~860 ℃溫度范圍內，變形溫度越高，越有利于組織球化。
In order to disclosure the influence of deformation temperature and deformation degree on β preforming acicular structure, small pie isothermal compressing test with different strain levels from 20% to 80% was carried out at four different temperatures ranging from 800 to 860 ℃. The results show that deformation degree is the key factor which influences the spheroidization of TC17 alloy. When the deformation rate is 40%?60%, lamellar structure of α phase is broken by the shear force and dynamic recrystallization takes place. When the deformation rate is higher than 60%, the spheroidization is effective. In the tempeature range of 800?860 ℃, the higher the temperature, the better the spheroidization.
