Initial permeability and vickers hardness of thermally aged FeCu alloy

“…The increase of permeability can be explained by the magnetic softening due to the decrease of Cu atoms forming precipitates in iron matrix. This phenomenon is similar in effect as seen in thermally aged other steels [3]. The cold-rolled specimens have already included a lot of dislocations before thermal aging.…”

Creep behaviour study of virgin and service exposed 5Cr–0.5Mo steel using magnetic Barkhausen emissions technique

“…Such microstructural change affects the mechanical properties of the material [5]. The estimation of material degradation to get the remaining life of the components is a challenge for modern society [6,7]. If such estimation can be done non-destructively, it will not only prevent the catastrophic failure of components but also save material loss and make the use of the components economical.…”

Ageing behavior study of 5Cr–0.5Mo steel by magnetic Barkhausen emissions and magnetic hysteresis loop techniques

“…Major emphasis on these studies has been concentrated on the evaluation of microstructure and its co-relation with mechanical properties of the materials [9][10][11]. Only a limited number of investigations have been carried out to understand the influence of microstructure on the physical properties of the high temperature Cr-Mo steel materials.…”
