    摘要:

    以6013型鋁合金為試驗(yàn)對象，研究了反復(fù)鐓壓工藝制備細(xì)晶材料，消除合金各向異性的可行性。采用金相顯微鏡，透射電鏡研究了6013型鋁合金反復(fù)鐓壓對合金組織和性能的影響。結(jié)果表明：反復(fù)鐓壓使合金內(nèi)部產(chǎn)生取向各異、彼此交錯(cuò)的變形帶，有利于細(xì)化合金組織，經(jīng)480 ℃, 2 h的退火處理后，合金發(fā)生再結(jié)晶，合金晶粒等軸化，大小分布均勻，與未反復(fù)鐓壓合金組織相比，晶粒顯著細(xì)化，減輕了組織各向異性；合金強(qiáng)度隨鐓壓道次的增加，先降低后升高，對鐓壓后的合金進(jìn)行T6處理（560 ℃, 2 h+191 ℃, 4 h），反復(fù)鐓壓3道次和12道次合金的硬度分別為1418.5和1503.5 MPa。研究表明：反復(fù)鐓壓工藝可以有效細(xì)化晶粒，消除組織各向異性，多道次鐓壓后，合金強(qiáng)度有所提高

    Abstract:

    6013 type aluminum alloy produced by cyclic channel die compression (CCDC) process was investigated to explore whether the fine grain and elimination of anisotropy can be obtained. Microstructures and properties of 6013 type aluminum alloy were tested by optical microscopy (OM), transmission electron microscopy (TEM) and hardness tester. The results indicate that CCDC process can effectively refine the grains and eliminate the anisotropy. Different-orientation, staggered belts are observed, which is conducive to refining the microstructure when the alloy is subjected to CCDC process. Recrystallization, equiaxed grains, and homogeneous distribution are gotten when the alloy is annealed at 480 oC for 2 h. The grains are significantly refined and the microstructural anisotropy is reduced compared with the alloy without CCDC. The strength of the alloy decreases first and then increases with increasing the passes of CCDC. The hardness (HV) of the alloy is 1418.5 MPa and 1503.5 MPa compressed by 3 passes and 12 passes, respectively, when the alloy was treated by T6 solution-aging (560 oC /2 h+191 oC /4 h). It is shown that the fine grain and elimination of anisotropy can be obtained and the strength would be increased after multi-passes CCDC
