Effect of Sr-modification on the bendability of cast aluminum alloy A356 using digital image correlation method

The effect of cast microstructure on bendability of automotive cast aluminum alloy A356 has been studied by machining sheet specimens and conducting V-bend tests. Specimens in the loaded condition are observed from the through-thickness section using a CCD camera and also using a scanning electron microscope (SEM). The latter allowed recording of high magnification images from the through-thickness region of the bend to determine aspects of …
