The aluminum beverage can is formed from a single sheet of an aluminum alloy. Production operations include? deep drawing forging extrusion die casting Which one of the following statements is NOT correct for the thermal processing of metals? full annealing treatment is followed by fast cooling normalizing can produce fine pearlite process annealing changes the microstructure of the deformed structure spheroidizing treatment increases a ductility of the steel Which one of the following casting process utilizes a permanent mold? sand casting die casting investment casting continuous casting Impact test using Charpy V-notch (CVN) involves except high strain rate triaxial stress notch plastic How many octahedral interstices in an FCC unit cell? 4 6 8 10 Which of the following materials is NOT a ceramic? silica glass SbN_4 Mg_2Pb whiteware By adding Y_2O_3 impurities to ZrO_2, what defects can be created? one Y_2O_3creates one oxygen vacancy one Y_2O_3creates one oxygen interstitial two Y_2O_3create one oxygen vacancy two Y_2O_3create one oxygen interstitial Carbon nanotubes have The following properties except: very high thermal conductivity very high mechanical strength very high oxidation resistance very high elastic modulus Shape memory alloys have the following characteristics except: martensite transformation original shape can be restored w hen heated above A_1 (austenite finish temperature) deformation must occur above M_1 (martensite finish temperature) deformation occurs by migration of twin boundaries
