Effect of “Incomplete” Austenitization Under Isothermal Quenching on the Structure and Properties of High-Strength Cast Iron Alloyed with Nickel and Copper

详细

The effect of the mode of isothermal quenching on the special features of formation of bainitic structures in high-strength cast irons with globular graphite is studied. The regular features of the influence of isothermal quenching on the mechanical properties of the alloyed irons are determined. It is shown that the process of formation of bainite in the irons is affected considerably by the austenitization temperature. Control of this temperature makes it possible to control the mechanical properties of the metal.
