Considering heavy forged parts presented that water spray is an appropriate technique as quenching operation. In general, the rapid cooling causes residual stress field due to the dis-homogeneity of the distribution of temperature in the part and the different microstructural phases. In comparison with other conventional quenching methods, spray-quenching method could have a capability to control the temperature distribution through the surface. In order to gain entry the appropriate mechanical properties, the spray control valves need to adjust to the foundation of heavy forgings cross sections. In this situation, the modelling of the spray quenching operation necessarily deserves for more elaboration. The present paper is aimed at developing and simulating a spray quenching process of a heavy forged shaft produced in a hardening and tempering steel.

Abstract
Considering heavy forged parts presented that water spray is an appropriate technique as quenching operation. In general, the rapid cooling causes residual stress field due to the dis-homogeneity of the distribution of temperature in the part and the different microstructural phases. In comparison with other conventional quenching methods, spray-quenching method could have a capability to control the temperature distribution through the surface. In order to gain entry the appropriate mechanical properties, the spray control valves need to adjust to the foundation of heavy forgings cross sections. In this situation, the modelling of the spray quenching operation necessarily deserves for more elaboration. The present paper is aimed at developing and simulating a spray quenching process of a heavy forged shaft produced in a hardening and tempering steel.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
