2011 JUL 6 - (VerticalNews.com) -- "The microstructures of U720Li disc superalloyrnhave been investigated by transmission electron microscopy (TEM) before and after creep test atrn725 degrees C/630 MPa. The evolution of the crept microstructures was marked as threerndifferent stages (I, II and III) corresponding to gradually increased strain 0.1%, 5% and 27%,rnrespectively," researchers in Ibaraki, Japan report.
