    • 摘要: 采用X射线衍射法测定了TA34钛合金管材经不同Q值冷轧后的宏观形变织构和退火织构,分析了冷轧Q值对管材织构、工艺性能和室温力学性能的影响。结果表明:冷轧Q值对管材的塑性影响不大;冷轧TA34钛合金管材形变织构和退火织构的总体类型相同,均为轴向织构;提高冷轧Q值会使完全再结晶退火后的TA34钛合金管坯产生周向织构,有助于提高成品管材的压扁工艺性能。

    • 摘要: 将6.5%Si高硅钢薄板在1000°C下保温1 h后,以不同冷却方式冷却,通过XRD测试分析试样的宏观织构和残余应力,采用EBSD测量试样的微观织构,并通过磁性测量仪测量磁感B8,研究冷却速度对6.5%Si高硅钢再结晶织构、残余应力以及磁感的影响.结果表明,再结晶退火后的冷却速度对6.5%Si高硅钢薄板再结晶织构的类型、含量以及分布无显著影响,但是随着冷却速度的降低,{100}和{110}面织构与理想取向的偏离程度减小,对提高磁感B8有利.(100)和(110)面的残余应力远大于(111)面的残余应力,且随着冷却速度的降低,试样中的残余应力逐渐减小,这是织构偏离程度发生变化的主要原因.随着冷却速度的降低,残余应力引起的晶格畸变减小,则磁化过程中磁畴壁的位移阻力减小,磁感B8逐渐增加.

    • 摘要: 采用晶体塑性有限元模拟与实验相结合的方式,研究无取向硅钢冷轧过程中不同初始织构组分的取向流动与形变储能累积.结果表明:冷轧后形成了较强的α,γ形变织构和较弱的λ形变织构.再结晶织构由γ,α,η和λ织构组成,其取向密度依赖于冷轧压下率.随冷轧压下率增大,λ再结晶织构逐渐增强,η织构先增强后减弱,γ织构先减弱后增强,α织构稍有弱化.冷轧过程中形变储能累积具有明显的初始取向依赖性,初始γ取向储能累积速率在低于50% 压下率时与初始α取向接近,高于50% 压下率时则明显大于后者,初始λ取向储能累积速率始终显著低于γ和α取向,转至同一形变取向的不同初始取向间的储能累积也会产生差异.冷轧过程中不同初始织构组分的取向流动与形变储能累积规律,决定了无取向硅钢再结晶织构组分的发展.

    • 摘要: 采用EBSD技术研究Al?(Mn)?Fe?Si合金等温退火后的再结晶晶粒结构.统计研究表明,在无沉淀反应条件下,在大于临界直径(约1.1μm)的颗粒相周围形成P取向({011}〈566〉)晶粒的频率约为2%.晶粒总数量密度与P、立方取向({001}〈100〉)晶粒的数量成线性关系.再结晶晶粒的总数量密度及典型取向(P、ND旋转立方{001}〈310〉、立方)晶粒的数量密度随轧制应变量增加而增加,并服从指数规律.%The recrystallized grain structure of Al?(Mn)?Fe?Si alloys after isothermal annealing was studied by electron backscatter diffraction (EBSD) technique. Statistical correlation suggests that the frequency of forming P-oriented ({011}〈566〉) grains at a particle larger than the critical diameter (about 1.1μm) is about 2% when the effect of fine dispersoids and concurrent precipitation is negligible. The overall grain number density is correlated linearly with the number densities of P and Cube ({001}〈100〉) grains. The grain number densities of typical orientations (P, ND-rotated cube {001}〈310〉 and Cube) and the overall recrystallized grains increase as rolling strain increases, following a similar exponential law.

    • 摘要: 将87%单向轧制钽板分别在800°C预退火0 min、5 min、15 min和30 min,然后把所有样品在1200°C退火30 min使其发生完全再结晶.采用电子背散射衍射(EBSD)、金相显微和显微硬度等技术表征了不同预退火时间后的微观组织及后续高温退火再结晶微观组织,结果表明,预退火30 min后再经后续高温退火的样品,其表面和中心的再结晶晶粒尺寸最为均匀细小,这主要是由于随着预退火时间的增加,形变晶粒内部的储存能不断的释放,这在一定程度上降低了后续高温退火过程中晶粒的长大速率.同时,低温退火时亚晶形核是主要的再结晶机制,预退火时间到30 min时,{100}形变基体内部出现较多的{100}取向再结晶晶粒,这有效弱化了后续高温退火{111}再结晶织构的强度,从而有利于随机织构的生成.

    • 摘要: 为了得到高份额立方织构金属基带,同时兼顾居里温度和屈服强度的要求,设计了Ni-7.8%Cr-1.1% Mo-1.6%W(原子分数)合金.采用冷坩埚悬浮熔炼技术冶炼合金铸锭,铸锭经过锻造、热轧、冷轧和再结晶退火,最终得到厚度为100μm的合金薄带.采用电子背散射衍射(EBSD)技术对合金薄带再结晶织构进行了表征,并研究了其磁性能及力学性能.结果表明:经大变形量冷轧和优化的两步法退火后Ni-7.8%Cr-1.1%Mo-1.6%W合金薄带立方织构份额为93.4%,小角晶界体积分数为84.5%;合金薄带的居里温度为25 K,远低于77 K;合金薄带室温下的屈服强度为182MPa,与Ni-5%W合金相当,且抗拉性能十分优异.%Quaternary Ni-7.8at%Cr-1.1at%Mo-1.6at%W alloy was designed based on the requirements of sharp cubic texture,lower Curie temperature and moderate yield strength for the substrate of 2G high temperature superconductor wire.The alloy ingot was prepared by using cold crucible induction levitation melting and a tape with a final thickness of 100 μm was obtained after forging,hot rolling,cold rolling and recrystallization annealing.The recrystallization texture of the alloy tape was characterized by electron back scatter diffraction (EBSD) technology and its magnetic and mechanical properties were also evaluated.The results show that the cubic texture percentage and the small angle grain boundary volume fraction of Ni-7.8at% Cr-1.1at% Mo-1.6at% W alloy tape reach 93.4% and 84.5%,respectively,after heavy cold rolling and two-step annealing.The Curie temperature of the alloy tape is 25 K,far below 77 K,and the yield strength of the alloy tape at room temperature is 182 MPa,equivalent to that of Ni-5at%W alloy tape.All this indicates that Ni-7.8at%Cr-1.1at%Mo-1.6at%W alloy tape possesses advantages over the available Ni-based alloy tapes and would substitute Ni-5at%W alloy tape for the coating of 2G high temperature superconductor.

    • 摘要: 采用取向分布函数(ODF)分析了无取向电工钢冷轧板施加不同张力时再结晶退火后组织织构的变化.结果表明,随着退火张力的增加,再结晶晶粒尺寸逐渐增大,当退火张力为4 MPa时,晶粒平均直径达最大值75 μm,且尺寸均匀,Cross织构和立方织构组分也增强,其铁损P1.5/50降低到4.34 W· kg-1,同时磁感Bs.升至1.684 T;当张力增加到6 MPa时,晶粒直径减小至40 μm,{110}和{001}织构组分减弱,γ线织构组分明显增强,磁性能恶化.%The recrystallization texture of non-oriented electrical steel under different annealing stress was investigated by orientation distribution function analysis.The result showed that the size of the recrystallization grain increased with the increase of annealing tension.When annealing tension was 4 MPa,the average diameter of grain reached the maximum of 75 μm with even size,and Goss texture and cube texture component were enhanced,as P1.5/50 was reduced to 4.34 W · kg-1 and B50 increased to 1.684 T.When annealing tension increased to 6 MPa,the grain size would decrease to 40 /μm,leading to the decrease of intensity of { 110 } (001) and { 001 } (100) texture,the increase of density of { 111 } fiber and the visible deterioration of magnetic property.

    • 摘要: 以不同高斯取向度的取向硅钢成品板为初始原料,采用一次冷轧法制备0.06~0.12mm厚的取向硅钢薄带.利用EBSD取向成像技术研究冷轧压下率以及初始高斯晶粒取向度对超薄取向硅钢织构演变与磁性能的影响.结果表明:随着冷轧压下率增大和厚度减小,退火后再结晶织构增强,当压下率为70%时,再结晶织构中RD∥〈001〉织构最锋锐,磁性能最佳;初始样品高斯取向度越高,制备的薄带样品磁性能越好;因此,生产高性能的取向硅钢薄带应选用初始高斯晶粒取向度较高的成品板.%The ultra-thin grain-oriented silicon steel strips with a thickness of 0.06-0.12mm were produced by one-step-rolling methods with different Goss-orientation of grain-oriented silicon steel sheets.The effect of cold rolling reduction and initial Goss-orientation of samples on texture evolution and magnetic performance of ultra-thin grain-oriented silicon steel strips was studied by EBSD.The result shows that with the increase of cold rolling reduction and decrease of strips thickness, the recrystallization texture is enhanced after annealing.When the cold rolling reduction is 70%,RD∥〈001〉 recrystallization texture is the sharpest, and the magnetic performance is the best.The higher degree of Goss orientation in initial sample is, the better magnetic performance of ultra-thin grain-oriented silicon steel.Therefore, for producing an ultra-thin grain-oriented silicon steel with high performance, a material with a concentrated orientation of Goss grains can be used.

    • 摘要: The texture evolution and the magnetostriction response of the recrystallized Fe81 Ga19 alloy thin sheet cold rolled with different reductions were investigated. It is revealed that the recrystallization texture is composed of Goss ({110} ) and γ ( //ND) texture, the characteristic of recrystallization texture is affected greatly by the reduction, attributed to the variation of deformed microstructure and texture. As the cold rolled reduction increases from 60%to 70% , Goss texture and magnetostriction value are enhanced by the increasing shear bands and strong {111} texture in deformed matrix. However, when the reduction is 80% , the Goss texture becomes weakened and the γ texture has been enhanced, resulted in a lower magnetostriction, because of the orientation deviation of nucleated grains in shear band caused by the texture variation in deformed matrix and shear bands, as well as more nuclear sites for recrystallized γ grains supplied by grain boundary with a higher storage energy.%对Fe81 Ga19合金进行冷轧与再结晶退火,考察了压下率对再结晶织构及磁致伸缩性能的影响.再结晶织构主要由Goss({110})和γ(//ND)织构组成,再结晶织构特征随压下率增加出现明显的改变,归因于变形微结构与冷轧织构的差异.冷轧压下率从60%增加到70%时,剪切带密度增加且{111}形变织构增强,提高再结晶Goss织构强度与磁致伸缩性能.压下率为80%时,剪切带与形变基体取向变化使剪切带晶核取向漫散,且晶界储能提高为再结晶γ织构提供更多形核位置,导致再结晶Goss织构减弱而γ织构增强,降低薄带磁致伸缩性能.
