College... the microstructure and electrical properties of Al–Zr–La alloys under different hot compression deformation temperatures. In particular, a Gleeble 3500 thermal simulator was used to carry out multi-pass hot......
mm and a width of 20 mm and a thickness of 3 mm were machined from the strip for uniaxial compression tests. Uniaxial compression tests were performed on a Thermecmastor-Z hot deformation simulator... subsequent hot rolling of as received twin-roll cast strip. The specimens were quenched by nitrogen gas immediately after compression in order to keep the microstructure after deformation. Texture......
