corner of Mg-Zn-Ce system at 350 ℃. Key words: Mg-Zn-Ce system; phase equilibrium; two-phase region; three-phase region; T-phase ... microscope(TEM) operated at 200 kV. Table 1 EPMA data of equilibrium phases in alloys (molar fraction, %) 3 Results and discussion 3.1 Equilibrium of T-phase+α(Mg) The microstructures......
, but the result is contrary by hand hammering. So it is obtained that whether the equilibrium phase can be obtain or not by the stress at room temperature mainly depends on the feature of deformation mechanism... for the transformation of metastable phase, so the equilibrium phase of alloy can not be gotten at room temperature. Key words: Al-Zn-Cu alloys; ball milling; hand hammering; stress induce phase transformation......

and XRD analysis together with EDS determination show that L12 type Co3Ti phase and Laves_C36_Co3Ta phase get equilibrium with α-Co phase from 1 000 to 1 200 °C. The Co3Ti phase possesses a solubility... to the result. Key words: L12 type intermetallic compound; phase equilibrium; Co-Ti-Ta; Co-based superalloys 1 Introduction The development of superalloys has been driven by the demand to increase......
of the solid phase; C0 is the nominal concentration of alloy. The KGT model[12] was used to calculate primary tip undercooling. It was founded based on researching of solute equilibrium at the dendrite tip[12... on describing the phase equilibrium at solid/liquid interface rightly. And any incorrect supposition may lead to false simulation results. At present, the best and the most accurate method to treat......
