AISI 4140 alloy steel is widely applied in the manufacture of various parts such as gears, rams, and spindles due to its good performance strength, toughness, wear resistance. The former researches most focused on deformation recrystallization behaviors under high temperature. However, evolution laws austenite grain growth were rarely studied. This behavior also plays an important role mechanical properties made this steel. In study, samples are heated a certain temperature 1073 K, 1173 1273...
Cu/Al clad sheets with a 304 stainless steel foil (SUS304) interlayer are successfully fabricated by the powder-in-tube method. The influence of SUS304 thickness on interfacial structure, elemental diffusion, and peeling strength is studied. Experimental results indicate that initial interface partially transformed into Cu/SUS304/Al after introducing interlayer. proportion fragments at bonding shown to increase Differences in deformability between matrix promote occurrence shear deformation...
