C型Laves相合金析出相层错叶恒强选区电子衍射CBED树枝状晶体倾转The dendritical spaped precipitates in GH 302 alloy were identified as C14 type Laves phase by means of CBED, SED and X-ray mitro-analysis.WANG DANENGArNe OLSENYE HENGQIANG王大能...
First of all, it should be noted that the formation of the Laves phase in the alloy is a gradual phase transformation process, the initial Laves phase is oversaturated with Ti and has a chemical composition close to that of Ti(Ti,Al)2, then with increasing isothermal holding time it ...

Phase stabilityElastic propertiesAnisotropyElectronic structuresThe structural and mechanical properties, Debye temperatures and anisotropic sound velocities of the Laves phases AlM (M=Mg, Ca, Sr and Ba) with C14-type structure were investigated using the first-principles corresponding calculations. The ...
We have performed first-principles calculations of hexagonal C14-type Laves phase Ti-Mn metals and their hydrides, namely, Ti1.0Mn2.0H3, Ti1.25Mn1.75H3, and Ti1.5Mn1.5H3, to understand their hydrogen storage properties, particularly focusing on materials trend of the heat of formation. We employ...
