Jiangsu Key Laboratory of Green Process Equipment, Changzhou University, Changzhou 213164, China) Abstract: The brass was induced by laser shot peening (LSP) with the laser pulse energy of 2.5 J and 4.5 J......
, Ministry of Education Central South University, Changsha 410083, China) Abstract: A new elastic alloy Cu-Zn-Al aluminum brass containing Ni and grain refiner was produced by casting and rolling... aluminum brass; nickel; microstructure; performance 铜基弹性材料中应用最广泛的是锡磷青铜和黄铜.锡磷青铜用途广,用量大,但由于世界锡资源短缺,同时锡磷青铜难以热加工,退火次数多,成品率低而造成能源大量消耗[1-2],导致合金成本较高.黄铜合金成本低,易制造,但其强度不高,脱锌及应力腐蚀开裂的倾向大,材料的综合性能较差[3-5].因此,需要通过添加微量元......
specimen were Brass {011} <211> and Cube {100} <100>. Textures of Brass {011} <211> and Goss {011} <100> were observed in specimen after deformation at room temperature; while textures of Brass {011} <211>, Goss {011} <100> and S {123} <634> were detected after deformation at cryogenic temperature. It is believed that the additional Al2O3 nanoparticles can......
that for the axisymmetric compressive deformation, Brass along the α-fiber and Goss present in the sample deformed at 350 ℃, Rotated-Cube was present and Brass transformed to Goss along α-fiber after annealing; Rotated-Cube appeared only in the deformation at 420 ℃, which decreased and Brass appeared after annealing. For the planar compressive deformation, Rotated-Cube and Brass aligned to α and β fibers present......
分布函数(ODF)以及晶粒取向汇集目标线(α,β取向线)研究合金冷轧板材中织构的形成及其在退火过程中的演变规律.结果表明:Al-Mg合金冷轧板材中主要存在Brass织构{011}á211?和Copper织构{112}á111?,退火温度升高到300 ℃时,Al-Mg合金板材的形变织构逐渐消失,Brass织构和Copper织构分别向立方织构{001}á100?以及旋转立方织构{001}á110?转变；添加Sc元素没有改变Al-Mg合金板材冷轧织构组分,但织构极密度和取向密度明显增强；退火温度升高到450 ℃时,Al-Mg-Sc合金板材的部分Brass织构和Copper织构才向立方织构和旋转立方织构转变,表明Sc的加入使Al-Mg-Sc合金在退火过程的再结晶温度显著提高. 关键词:Al-Mg-Sc合金；织构；退火；取向分布函数 中图分类号:TG146.2 ......
solutionization is not recrystallized and contains 55.28% deformation textures of Brass and S. In the cold-rolled sheet after solutionization, massive recrystallization occurs and S component disappears. Due to the higher fraction of Brass and S textures with higher Schmid factor and lower equivalent sliding system number, the extruded plate possesses an yield strength not higher or even lower......
nucleation and recrystallization occur in 6016 aluminum alloy during hot compressing, and strong rolling textures such as h110 i fiber texture, Brass, S, and Goss form. With the deformation passes increasing, h110 i fiber texture, Brass and S are enhanced. In the heat preservation stage after deformation, recrystallization continues until heat preservation for 60 s, and a duplex microstructure......
