Abstract： Microstructural evolution in a new kind of aluminum （A1） alloy with the chemical composition of AI-8.82Zn-2.08Mg- 0.80Cu-3.31Sc-0.3Zr was investigated. It is found that the secondary phase MgZn2 is completely dissolved into the matrix during a short homogenization treatment （470℃, 1 h）, while the primary phase A13（Sc,Zr） remains stable. This is due to Sc and Zr additions into the A1 al- loy, high Zn/Mg mass ratio, and low Cu content. The experimental findings fit well with the results calculated by the homogenization diffusion kinetics equation. The alloy shows an excellent mechanical performance after the short homogenization process followed by hot-extrusion and T6 treatment. Consequently, a good combination of low energy consumotion and favorable mechanical properties is obtained.

作者： chun-bo HUANG Tian-cheng LIU Xiang-yue WANG Cao-wei LU De-ren LI Zhi-chao LU China Iron and Steel Research Institute Group R&D Center of Advanced Technology and Materials Co. Ltd.

Toroidal shape FeCuNbSiB nanocrystalline alloy powder cores were prepared by cold pressing using me- chanically crushed and ball-milled powders, respectively. The morphologies and their effects on the magnetic proper- ties of the compacted cores were investigated. Compared with ball-milled powders, mechanically crushed ones have more regular shapes and rounder edges, which lead to better inter-particle insulation. FeCuNbSiB nanocrystalline al- loy powder cores fabricated from mechanically crushed powders exhibit remarkably lower core loss of about 248.2 kW/m3 at 100 kHz for maximum flux density Bm 0.1 T, and more stable permeability up to 10 MHz. Moreover, the dc-bias property could be improved significantly using mechanically crushed powders.

针对热强旋过程的变形特点,本文研究了基于平面应变压缩的物理模拟模型对钛合金热强旋过程的组织性能演变预测的可行性.为此本文对TA15钛合金平面应变压缩变形的组织和热强旋过程进行了对比分析,并以平面应变压缩的组织性能演变模型为基础,采用BP神经网络对TA15钛合金热强旋旋过程的组织性能进行了预测.研究结果表明,TA15钛合金平面压缩变形和热强旋过程的组织性能演变规律基本一致,采用平面应变压缩的组织性能模型可有效预测钛合金热强旋过程的组织演变.但是,由于强力旋压的多道次累积变形较平面压缩的单道次变形更为均匀充分,使得大减薄率时的预测误差略有增大趋势.

针对飞机蒙皮搭接处的划痕损伤问题,研究了含划痕缺陷的含铆钉孔2198-T8铝锂合金板材的疲劳性能。首先,利用Abaqus有限元仿真软件,通过正交试验法确定了划痕关键影响参数,优化了疲劳试验方案。其次,预制了9类划痕损伤试样,分析了划痕参数对其疲劳性能的影响,并结合数字图像相关技术对裂纹扩展路径进行了讨论。最后,利用体视显微镜及扫描电子显微镜对断口进行了表征并分析了疲劳断裂机理。结果表明,划痕尖端角度θ对力学性能影响最小;划痕深度D是影响疲劳性能的主要因素。在D=0.8 mm、c=72 mm、θ=45°的损伤条件下,疲劳寿命下降至1795次,较无损试样下降97.66%。当D>D_(s)=0.15 mm时,断裂位置由铆钉孔截面转移至划痕截面,且断裂模式由单一疲劳源扩展的韧性断裂转变为多疲劳源放射状扩展的准解理断裂。

目的定性分析不同基底材料与饰面瓷之间化学结合的方式。方法本研究于2011年3—9月在大连市口腔医院和大连交通大学完成。以上颌侧切牙为模型,选用镍铬(Ni-Cr)合金、氧化锆、金钯(Au-Pd)合金、压铸瓷、钴铬(Co-Cr)合金、混合Au-Pd合金6种基底材料,按照厂家的操作要求在不同基底材料上烧结饰面瓷。然后用扫描电镜观察各基底材料与饰面瓷界面,并用能谱分析仪进行元素分析。结果 Ni-Cr合金、氧化锆、Au-Pd合金、Co-Cr合金、混合Au-Pd合金5种基底与饰面瓷之间均发生了程度不同的元素扩散,扩散范围约1～2μm。随着远离界面,扩散元素含量逐渐降低直至消失。压铸瓷基底在实验条件下未明显观察到饰面瓷与压铸瓷的结合界面。结论 Ni-Cr合金、氧化锆、Au-Pd合金、Co-Cr合金、混合Au-Pd合金及压铸瓷基底在和饰面瓷的烧结过程中均发生了化学结合。
