The rolling and recrystallization texture of B2 type Fe3Al based alloys were systematially investigated by ODF. The results showed that the rolling texture consisted of a strong β-fibre close to {111} and a {001} <110> texture. In annealing process the rolling texture was strengthened at recovery stage and gradually disappeared during primary recrystallization. A strong shear texture was produced by only 20% Pass reduction, indicating that the Fe3Al is sensitive to shear stress. The corresponding room temperature tensile properties were measured. A correlation between texture mode and room temperature mechanical properties was observed.

在真空熔炼炉中于氩气气氛保护下熔炼出Mg-12Li-0.5Al-1Zn(LAZ1201)合金铸锭,开坯后进行了不同变形量(30％,50％,70％)的热轧,研究了轧制变形量对合金显微组织及力学性能的影响,并对铸态和轧制态室温拉伸断口形貌进行了观察.结果表明:随着变形量的增大,合金发生了不完全动态再结晶,晶粒细化,合金的抗拉强度逐渐升高,伸长率先大幅升高,然后有所下降;当轧制变形量为70％时,抗拉强度可达166 MPa;轧制变形量为30％时,合金的塑性最好,伸长率可达50％;铸态和轧制态合金的室温拉伸断口上均存在大量等轴韧窝,为韧性断裂.

对Al-Ga-Mg-Mn-Bi阳极合金固溶处理和常温轧制变形,测量不同处理状态下的电化学阻抗谱、极化曲线、自腐蚀速率等,研究固溶和轧制处理对该合金的组织及电化学性能的影响.结果表明:与铸态试样相比,固溶处理减少了铝阳极组织中第二相的数量,较大程度地降低铝阳极的自腐蚀和析氢速率,改善了合金的腐蚀形貌,使恒流放电的电位负移;轧制处理使恒流放电的电位负移,能够明显改善铝阳极的腐蚀形貌.
