The liquidus projection of the B-Fe-Mo system in the Fe-rich region has been proposed based on the microstructural characterization of arc-melted alloys through powder X-ray diffraction measurements, differential thermal analysis, and scanning electron microscopy observations complemented by energy dispersive X-ray spectroscopy.Five different primary solidification regions were observed: α-Fe, γ-Fe, FeMo2B2, Fe2B, and Fe3Mo2.The following ternary invariant reactions are proposed to occur in the region of Fe-rich corner: U1: L+α-Fe(=)y-Fe+FeMo2B2;E1: L(=)-Fe+Fe2B+FeMo2B2;E2: L(=)R+FeMo2B2+α-Fe.

It is well known that many aluminium alloys attain optimum properties due to the formation of age-hardening precipitates, most of which are metastable from the thermodynamic point of view.Those age-ha
Due to its shape memory effect and superelastieity, shape memory alloy is one of the attractive smart materials which has been paid attention on for decades.Especially in Ni based, Cu based, CoNi base
TbMnO3是一种被广泛研究具有ABO3钙钛矿结构的多铁化合物.在其A或B位掺杂一些其它元素可以明显改变材料的多铁特性.先前的研究表明TbMnO3中位于A格位的Tb可以被Mn取代,这样可以获得组成为(Tb1-xMny)MnO3-的固溶体.初步研究表明其中x,y值不同的两个样品在低温下具有各自不同的磁结构.于是对整个固熔体进行了细致的研究.在低温下，这类化合物具有三种有序磁结构A(Tb的螺旋反铁磁有

通过向不同成分的Zn-Al熔池中添加一定量的Mg元素,研究了热浸镀Zn-Al-Mg镀层中周期层状组织的形成条件,利用扫描电镜SEM及能谱EDS观察分析了各个样品的镀层组织.结果表明,在Zn-Al-0.5％Mg的熔池中,当Al含量为30％、45％、55％时,能够形成周期性的层片组织.随着Al含量的增加,FeAl3与Al-Zn二元共晶并存的周期层状组织的形成也越明显.当Al含量较低时,Mg含量的增加会
本研究采用分子动力学模拟方法研究了Cu50Zr50非晶合金的形成过程及其局域原子结构.模拟得到的玻璃转变温度和径向分布函数与实验结果吻合较好.对非晶形成过程中的结构演化的键对分析表明:随着温度降低,具有五次对称特性的1551、1541键对数量单调增加,而1431键对则是先升高后降低;同时,非晶合金中以与二十面体短程序相关的1551,1541和1431键对为主.配位数(CN)和Voronoi多面体结
通过VASP计算了Cr-Nb和Zr-Cr体系中的Laves端基形成能.通过SQS耦合VASP计算出上述体系中溶体相形成焓,并运用到热力学优化中去.对于存在争议的Cr-Nb体系中高温C14相稳定性问题,本文通过声子计算得到随温度变化的自由能,从而分析其相稳定性.通过合金法测定了Zr-Cr相图部分溶解度范围.通过上述数据,优化出Cr-Nb和Zr-Cr相图,并拓展得到Zr-Nb-Cr三元热力学优化参数.
