Acta Metallurgica Sinica(English Letters) 2024年第7期37卷 1186-1200页

Here, the composition of TaMoNbZrTiAl refractory high entropy alloy (RHEA) is optimized by increasing Ti content to improve its mechanical property especially the ductility, through comparing two RHEAs with different Ti content. The RHEAs contain two body-centered-cubic (BCC) phases. The BCC phase in the dendritic region is rich in Ta, Mo and Nb, and the BCC phase in the interdendritic region is enriched in Zr, Ti and Al. The as-cast RHEA with a higher Ti content remains dendritic microstructures, and Ti is mainly enriched in the interdendritic region. After annealing treatment at 1300 ℃ for 48 h, the dendritic microstructures change into equiaxed-grain morphology, accompanied by needle-like micron precipitates at grain boundaries in the RHEA with higher Ti content. For the as-cast RHEAs, the fracture strain increases by ~ 6.6% and the uniform plastic strain increases by ~ 5.9% at the compression test due to the increase of Ti content. Our work offers a reference for the composition design of RHEAs and makes a preliminary exploration of the optimization of the microstructures and mechanical properties.

混凝土细集料的主要来源天然砂被过度开采导致资源枯竭和环境破坏,采用机制砂替代天然砂是解决途径之一。石粉是机制砂生产中的副产品,适量的石粉可改善混凝土级配,但石粉含量过高会导致混凝土强度降低、强度离散性增大等问题,因此,《建设用砂》(GB/T 14684)中规定机制砂的石粉含量应不高于10%,但机制砂的石粉含量是实际工程中较难控制的问题。文章研究了硫酸钙晶须(CSW,5kg/m~3)对机制砂混凝土中石粉的改性作用:设计了在不同石粉含量(10%、15%、20%)下掺入硫酸钙晶须的机制砂混凝土的力学性能试验,并采用聚丙烯纤维(PPF,1kg/m~3)进行了对比,结果表明,未掺入纤维时,10%石粉含量的试件组力学性能高于15%和20%石粉含量的试件组;掺入CSW与PPF后,15%石粉含量的试件组力学性能最优,且CSW的改性作用较PPF明显。在试验基础上,基于可压缩堆积理论,考虑CSW的改性作用,建立了CSW改性高石粉机制砂混凝土强度模型,并进行了模型参数分析。

钢筋混凝土桥梁在服役期间,梁体受荷载作用可能会产生开裂,这种开裂会使外界环境的侵蚀作用更加严重。文章开展弯曲荷载作用下硫酸钙晶须混凝土的碳化试验研究,分析加载级别、硫酸钙晶须掺量对混凝土碳化速率的影响。试验结果表明:掺加硫酸钙晶须的混凝土抵抗碳化的能力比普通混凝土有明显提升;随着晶须掺量的增加,混凝土抵抗碳化的能力有所下降;弯曲荷载作用下,试件受压区碳化深度明显小于受拉区碳化深度,并随着弯曲荷载的增加,差距更为显著;基于硫酸钙晶须在混凝土中的荷载分担作用和弯曲荷载作用下混凝土梁截面的受力特性,考虑应力在截面上的不均匀分布,建立弯曲荷载作用下硫酸钙晶须混凝土的碳化计算公式。

当前,机制砂是代替天然河砂最普遍的材料,但机制砂存在级配不均匀、石粉含量过高、生产过程消耗能源和污染环境等问题。该文结合我国西部地区沙漠砂资源丰富的情况,开展了沙漠砂+机制砂混凝土(Desert sand+Machine-made sand Concrete, DMC)的力学性能试验,分析了不同沙漠砂替代率对混凝土强度和弹性模量的影响规律:DMC的强度与弹性模量随龄期逐渐增长,养护14d和28d时DMC轴心抗压强度随着沙漠砂替代率的增加呈现出先增大后减小的趋势,当沙漠砂替代率为20%时达到峰值。试验发现,DMC抗压强度受沙漠砂替代率的影响要大于弹性模量的影响。基于混凝土可压缩堆积理论,考虑沙漠砂和机制砂混合后堆积密度的变化及机制砂与沙漠砂在外观几何形状上的差异,并将混凝土二元混合料堆积模型扩展到细骨料堆积物理参数的分析中,建立了DMC抗压强度预测模型,模型精度较高。通过案例分析,在保证车站结构材料具有较好的力学性能前提下,当采用20%DMC时,由于减少了细骨料中机制砂的使用,案例的材料碳排放较低。
