Description
Summary:The effect of alloying and cooling conditions on the microstructure and properties of complexly-alloyed iron intended for operation under the action of abrasive conditions is considered. Irons alloyed with Cr, Nb, B, Si, Mn, and Ti are studied. A change in chemical composition and crystallization conditions has a marked effect on experimental alloy microstructure. A change in alloying element content and cooling rate causes a change in carbide phase type and morphology, distance between carbide particles, and the amount and size of austenite dendrites. By regulating the cooling rate and alloying element content within iron it is possible to control its structure, and through this iron properties.
