The results of the experiments show that the ti3al-tcll dual alloys, by vacuum-electron-beam weld, hot die forging and 680c / 12h, ac, heat treatments, have satisfied synthesis properties of intensity, plasticity, hardness . and also it is the feasiblie way . this will establish the supporting technology for the manufacture of the compress disk in the areoengine 實驗結(jié)果表明,經(jīng)真空電子束焊接ti_3al?tc11雙合金經(jīng)過熱模鍛造和68012h,ac或8151h+7008h,ac熱處理后,焊接區(qū)組織過渡均勻,可以使得焊縫處強度在室溫拉伸時高于ti_3al,而在600拉伸時高于tc11合金,獲得強度、塑性、硬度均令人滿意的綜合性能,且是一條可行的工藝路線。
What's more, the application of tc11 two phase alloys to the compress disk of areoengine alredy is relatively mature, and tc11 alloy may work safely for very long time below 500 c . ti3al matrix alloy and ( a + b ) two phase alloy is connected by weld . the request of the temperature and stress can be satisfied by dual alloy disk with isothermal forged ( or hot die forging ) 選用ti_3al基合金tac-1b和tc11兩相鈦合金用焊接工藝連接起來,通過熱模鍛或等溫鍛鍛造和不同的變形熱處理制度,制造出雙合金盤可以滿足溫度、應力對盤件的要求。
compress disk is the very important rotational component in the areoengine . when the compress disk is working, the grads of temperature and stress between the rim and the center of the disk are great . in order to raise the thrust-weight ratio of the disk and reduce oil consumption . the best prospective way is the dual alloys disk used 壓氣機盤是航空發(fā)動機上一個很重要的轉(zhuǎn)動部件,壓氣機盤工作時,輪緣和輪轂溫度梯度和應力梯度較大,為了提高飛機發(fā)動機推重比、減低耗油量,要求壓氣機盤的工作溫度、使用性能更高,雙合金盤制造是最有發(fā)展前景的技術(shù)。
