Abstract

AE961W martensitic steel material is heavily used for the applications of expendable gas turbine engine development. As a mandatory it is needs to be characterised for its quality for the critical applications. Metrology and NDT methods have been used for its characterisation in the current study. Samples have been prepared with necessary metrological characteristics and are subjected to various heat treatment conditions. The velocity (longitudinal and shear) and magnetism measurements are carried out to assess the effect the heat treatment conditions on the velocity values.
