In the present work, a non-destructive thermographic method for evaluating the effectiveness of heat treatment in boron steel has been developed.

Abstract
In the present work, a non-destructive thermographic method for evaluating the effectiveness of heat treatment in boron steel has been developed. Considering that the thermal properties of steel are strictly connected with micro-structure, an active thermography technique has been used for measuring the thermal diffusivity, adopting a reflection mode set-up. A numerical approach through the Finite Element Analysis has been adopted to select suitable experimental test parameters. Two boron steel (Usibor® 1500 specimens with different structures (ferritic-paerlitic / 100% martensitic) have been experimentally investigated by two thermographic methods in transmission and reflection mode results have been compared with a semi-destructive hardness test to validate the method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
