LD5 somewhat less. (2) with deformation temperature, the flow stress decreased. Really should be increased. However,moncler günstig, the magnitude of the increase of different,moncler daunenjacke, IYl2 compared with the magnitude of the increase LF3 fire. LD5 a lesser extent increased. (3) the strain rate decreased,ugg milano, in eo <2xl0S below. True stress decreased obviously. The true strain increases rapidly.
