Microstructure of Ti_3Al-11Nb alloy after heating at 1040-1120℃ and water quenching has been investigated by TEM and EDS.It was showed that all microstructure consisted of α_2-,B2-and O-phase.The O-phase could be divided into two types,twin-like and plate-like,according to its morphology.Their single crystal SADPs could be indexed according to a NaHg structure with paramerers of a=0.6232nm,b=0.9978nm and c=0.4725nm.The composition of the twin-like O-phase was identical with the α_2-phase.The Nb content of the...

Microstructure of Ti_3Al-11Nb alloy after heating at 1040-1120℃ and water quenching has been investigated by TEM and EDS.It was showed that all microstructure consisted of α_2-,B2-and O-phase.The O-phase could be divided into two types,twin-like and plate-like,according to its morphology.Their single crystal SADPs could be indexed according to a NaHg structure with paramerers of a=0.6232nm,b=0.9978nm and c=0.4725nm.The composition of the twin-like O-phase was identical with the α_2-phase.The Nb content of the plate-like O-phase was near to that of α_2-phase and its Al content was more than that of later. Perhaps,the twin-like O-phase was transformed from quenching α_2-phase under the action of stress.The plate-like O-phase had several types of morphologies and its volume percentage in the structure tended to increase with the decreasing of quenching temperature. Perhaps, it formed in the structure during the quenching heating. Volume percentage, morphology and interaction of α_2-,B2-and O-phase in the structure have obvious effects on the roomtemperature tension property of the alloy.

用TEM和EDS研究了在1040-1120℃加热后水淬的Ti_3Al-11Nb合金热锻棒材样品的组织结构。结果表明,样品组织均由α_2,B2和O相三相组成。O相从形貌上可分为孪晶状和板条状两种。它们的单晶选区电子衍射花样,均可按晶格参数为a=0.6232nm,b=0.9978nm和c=0.4725nm的NaHg结构加以标定。孪晶状O相的成分与α_2相的成分一致。板条状O相的成分中,Nb含量与α_2相的Nb含量相近,而Al含量则较α_2相的Al含量高。孪晶状O相可能是淬火α_2相在应力作用下转变来的。板条状O相组织在形貌上有多种,且随淬火温度降低,在数量上有增加的趋势。它可能是在淬火加热温度就存在,而在淬火过程中保留下来的。淬火组织中3相的数量、形貌及其相互作用显著影响了材料的拉伸性能。

The effect of predeformation degree on tension property of 8090 Al-Li alloy before aging is studied by using transmission and scanning electron microscopes and tensile machine. The result shows that Al-Li alloy has not only much higher strength but also much more plasticity when predeformation reaches 4%~5% degree. TEM and SEM analysis shows the one reason that Al-Li alloy can get optimum combination of strength and plasticity by using proper predeformation is all the action coming from the defferent strengthening...

The effect of predeformation degree on tension property of 8090 Al-Li alloy before aging is studied by using transmission and scanning electron microscopes and tensile machine. The result shows that Al-Li alloy has not only much higher strength but also much more plasticity when predeformation reaches 4%~5% degree. TEM and SEM analysis shows the one reason that Al-Li alloy can get optimum combination of strength and plasticity by using proper predeformation is all the action coming from the defferent strengthening mechanism in and between alloy laminates when Al-Li alloy has been broken on stratify. The other is that predeformation may facilitate compound precipitation at δ′ phases and S′ phases so that Al-Li alloy can gain more strength and plasticity in laminates.

用透射电镜、扫描电镜和拉伸试验机研究了时效前的预变形度对8090 Al-Li 合金拉伸性能的影响。结果发现,预变形为4 % ~5 % 时,Al- Li 合金不但具有较高的强度,也具有良好的塑性。试样的TEM 和SEM 分析表明,适当的预变形之所以能使Al- Li 合金获得最佳的强度和塑性的配合,除了由于预变形可促使δ′和S′相的复合析出,而使层内的强化和韧化作用加强外,也源于Al- Li 合金分层断裂后层间强化韧化和层内强化韧化的协调作用的结果。
