Microstructure,texture,and mechanical properties of the extruded Mg-2.49Nd-1.82Gd-0.2Zn-0.2Zr alloy were investigated at different extrusion temperatures(260 and 320℃),extrusion ratios(10:1,15:1,and 30:1),and extrusion speeds(3 and 6 mm/s).The experimental results exhibited that the grain sizes after extrusion were much finer than that of the homogenized alloy,and the second phase showed streamline distribution along the extrusion direction(ED).With extrusion temperature increased from 260 to 320℃,the microstructure,texture,and mechanical properties of alloys changed *** dynamic recrystallization(DRX)degree and grain sizes enhanced as the extrusion ratio increased from 10:1 to 30:1,and the strength gradually decreased but elongation(EL)*** the extrusion speed increased from 3 to 6 mm/s,the grain sizes and DRX degree increased significantly,and the samples presented the typical-rare-earth(RE)*** alloy extruded at 260℃ with extrusion ratio of 10:1 and extrusion speed of 3 mm/s showed the tensile yield strength(TYS)of 213 MPa and EL of 30.6%.After quantitatively analyzing the contribution of strengthening mechanisms,it was found that the grain boundary strengthening and dislocation strengthening played major roles among strengthening *** results provide some guidelines for enlarging the industrial application of extruded Mg-RE alloy.

为了提出断层弯曲破碎带概念,并探讨其对岩溶储集层发育的控制作用,调研了前人对断层破碎带的研究成果,以塔中北斜坡的三维地震数据体为基础,对断层弯曲破碎带进行识别,并利用均方根振幅属性等多种储集层预测技术对岩溶储集层进行预测。结果表明,断层弯曲破碎带是断层破碎带的一种重要类型,走滑断层破碎带可划分为端部、连接、弯曲、围岩4种破碎带类型。塔中ZG8-ZG11井区发育走滑断层弯曲破碎带,破碎带区域内奥陶系深部岩溶储集层发育。分析认为,弯曲破碎带内发育与主干走滑断层大角度相交的伴生断层,形成连通的网状断层系统,深部热液通过主干走滑断层进入网状断层系统,在埋藏溶蚀作用下围绕断层交叉区域形成优质岩溶储集层。综上所述,走滑断层弯曲破碎带对塔中深部岩溶储集层发育有控制作用。
