The Microstructure Evolution and Mechanical Properties of (FeCoCrNi)100‐x(AlCu)x High‐Entropy Alloys
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT This study systematically investigates the effects of AlCu addition on the microstructural evolution and mechanical properties of (FeCoCrNi)100‐x(AlCu)x (x = 0, 5, 10, 15, 20; at%) high‐entropy alloys (HEAs). The results reveal that the microstructure evolves from coarse equiaxed to refined equiaxed, dendritic, and ultimately dual‐phase ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT NiFe‐based MIL‐55 metal‐organic frameworks (MOFs) face challenges in achieving atomically precise composition and reliable methods for uniform growth. This study addresses these challenges by applying a slow evaporation crystallization technique to crude colloidal MIL‐55 products from hydrothermal synthesis, resulting in highly uniform ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

Gongye shui chuli, 2008 针对钠离子交换树脂再生过程排放的高含盐废水，研究了沉淀法的脱盐效果。比较了不同沉淀剂复配的处理效果，筛选出适于处理高浓度含盐废水的药剂HJ-C/B并进行了分步沉淀实验。结果表明：该法对钙离子去除率可达100%，镁离子去除率为99%以上。分离出沉淀后的澄清液可回用于树脂再生过程，其中氯离子(Cl~-)回用率为77%。该法不仅可大大减少高浓度含盐废水的排放，而且节约部分工业盐，并可回收纯度较高的沉淀。

Gongye shui chuli竖流沉淀依靠絮体自然沉淀和悬浮区拥挤沉淀实现固液分离，适度絮凝能充分发挥二者的协同作用，降低药剂投加量，提高沉淀效果。为了明确悬浮区的作用，开展了连续流竖流沉淀试验，考察测试不同工况下絮体的形态、悬浮区状态、沉淀效果等变化规律，重点分析了轻度絮凝、中度絮凝和重度絮凝3个典型的工况。结果表明：轻度絮凝的絮体自然沉降效能和悬浮区拦截效果均不佳；重度絮凝虽然絮体自然沉降效果好，但是悬浮区拦截效果较差；只有中度絮凝可以较好地平衡絮体自然沉降和悬浮区拦截的协同作用，沉淀效果最好，对应的絮体分型维数为1.83 ...

, 2012 应用电化学方法研究了混价铁氢氧化物对磷的吸附/沉淀及主要环境因素的影响。结果表明,混价铁氢氧化物通过吸附/沉淀可将水溶性磷维持在较低水平,该吸附较好地符合Langmuir方程(R2=0.9742),混价铁氢氧化物对磷的最大吸附容量为56.8 mg/g;亚铁比例越高,单位铁的磷吸附/沉淀容量越高;混价铁氢氧化物氧化导致磷吸附容量降低;pH为中性时,混价铁氢氧化物的磷吸附容量最大,弱酸、弱碱性则不利于磷的吸附;钙离子可增加混价铁氢氧化物的磷吸附容量;硫离子则相反,原因是硫离子促进了三价铁还原及硫化亚铁的形成;
