Improvement of mechanical properties of iron castings via adjusting of solidification rate

Abstract: The work is devoted to improvement of mechanical properties of iron castings via adjusting of the cooling rate without introduction of alloying additives. The new technological solution is suggested; it can be easily adapted to a casting technology. This solution is based on variation of the cooling rate of iron castings within structurally sensitive solidification intervals. For this purpose, the casting mould was initially cooled after pouring, then heated and cooled again. Cooling of the mould during the pe… Show more

“…Testing of the concrete procedures for mould blowing with compressed air as well as choosing of required amount of exothermal carbon-containing additive were conducted during the investigation (Table 2). Fuel oil M-100 was taken as this exothermal carbon-containing additive [21,22]. The specimens for metallographic examination and mechanical testing were cut from the obtained castings.…”
