. The plate-shaped β exhibits (0001)α//(111)β, deviates by about 9? from (OR-4, a new OR). Key words: Mg-Sn alloy; crystallography; Mg2Sn precipitate; orientation relationship ... is parallel with <>α According to the morphology, one can see that lath-shaped precipitate D grows perpendicular to B. Its OR is different from OR-1. The diffraction pattern of precipitate D is shown......

; precipitate; recrystallization resistance 1 Introduction A tremendous amount of research has been carried out on Sc-containing Al alloys over the last 20 years, owing to the improved properties... time for precipitation of the Al3Zr precipitate. In order to study the effect of scandium on the Al3(Sc,Zr) precipitates by TEM, all as-cast specimens from six alloys were annealed at 475 ℃ for 12 h......
precipitate can significantly reduce the carrier lifetime of multicrystalline silicon due to their Schottkydiode behavior in the silicon substrate. A 900 °C rap thermal process (RTP) phosphorus gettering anneal cannot be sufficiently effective to remove the Cu precipitates in these two regions. Key words: multicrystalline silicon; Cu precipitate; phosphorus gettering; defects; carrier lifetime 1......
