镍基高温合金长期在高温、高压、高速和交变载荷等复杂的环境中服役,容易产生周期性应变集中的塑性变形,引起应变控制的低周疲劳(LCF)损伤。镍基变形高温合金服役过程中产生的低周疲劳严重降低了热端部件的服役性能和寿命。因此,阐明镍基变形高温合金LCF塑性变形行为及疲劳断裂机制对于涡轮盘等热端部件的可靠性和安全性服役具有重要的现实意义。综述了晶粒和析出相微观组织等内部因素,以及温度、加载频率、加载波形和应变幅等外部因素对镍基变形高温合金低周疲劳性能的重要影响;揭示了循环硬化、循环软化产生的各种微观机制;叙述了几种
采用GH4169粉末对航空发动机材料GH4169合金进行激光修复试验,测试修复试样与母材试样的室温、高温拉伸性能、疲劳性能,将两者之间以及和材料标准进行对比,并进行组织分析。研究表明,在合适的工艺参数下,热影响区很窄,仅为0.1~0.2 mm,熔覆区冶金质量良好,未见明显空洞和熔合缺陷等;修复试样的室温拉伸强度达到1299 MPa,高温拉伸强度达到1069 MPa,与母材相当,且高于材料标准;塑性降为母材的50%;修复试样横向取样疲劳性能高于母材标准,纵向取样疲劳性能稍低于母材标准,但同属于一个数量级。激
采用化学选择性浸出方法对沉积型胶磷矿中稀土元素的赋存状态进行研究。研究发现沉积型磷矿主要由碳酸盐相、磷酸盐相和硅酸盐相三相组成。各相最佳分相反应条件为:碳酸盐相控制乙酸浓度0.3%~0.5%,浸出温度为60℃,浸出时间90 min,分步浸出两次;磷酸盐相浸出条件是在10%~20%硝酸,浸出温度为60℃,浸出120 min,硅酸盐相采用四酸(盐酸、硝酸、氢氟酸及高氯酸)消解。结果表明,沉积型磷矿(昆阳、晋宁、贵州)中稀土元素少量以独立矿物的形式存在,主要以类质同像存在于磷灰石中,磷灰石中稀土含量占总量的98
锂辉石赋存的伟晶岩矿床因风化蚀变作用,矿石易于泥化,而细泥因表面积大、表面能高、吸附特性强烈,易吸附罩盖于矿物表面,降低矿物可浮性及矿物间表面性质差异,致使锂辉石与脉石矿物难以高效分离。为提高锂辉石-脉石-细泥多元体系中矿物浮选分离效果,通过浮选试验、浊度分析、扫描电镜分析、Zeta电位分析及X射线光电子能谱(XPS)分析,开展了锂辉石矿浆流体环境优化研究,结果表明氢氧化钠、碳酸钠协同调浆及延长搅拌时间,可使硅酸盐矿物表面元素自发溶解并键合大量阴离子,提高矿物表面电位负值,增加矿物颗粒间静电斥力,强化矿物
