... in the isothermal TTT diagram for 4340 steel ( Fig. 6.13 ). Such bays correlate with the presence of substitutional alloying elements that may partition to or from ferrite and concentrate at austenite-ferrite interfaces, creating a solute drag , or significant restraining force, on the formation of bainitic...

Much like carbon, these substitutional alloying elements prefer to partition into either the ferrite or cementite lamellae of the pearlite. Because the rate of pearlite formation depends heavily on diffusion...

... on the composition of the metal. Small SDASs are associated with higher strengths and improved ductility ( Fig. 7.12 ). Homogenization heat treatments are also dependent on the time, t , required to diffuse a solute over a given average distance, x . If the coefficient of diffusion in the solid is D...

... boxes are filled with specially bonded core sand and compacted much like the mold itself. Cores are placed in the drag, or bottom section, of the mold, and the mold is then closed by placing the cope, or top section, over the drag. Mold closing completes the production of the mold, into which the molten...
