Long-range order in Fe-Al alloys—II thermoelectric power

In situ strained Inconel 718 superalloy studied by thermoelectric power technique

“…In cast duplex stainless steel, TEP was a good method to evaluate thermal aging, possibly caused by the concentration of Cr [7,13]. The critical temperature for the Fe 3 Al was marked by a sharp change in the slope of TEP versus temperature plot and the phase boundary was also accordingly determined [14]. Moreover, microstructural changes have been successfully studied by TEP technique in ELC steels [15], 6061 Aluminium [16] and Al-Mg-Si alloy [17].…”

Changes in the thermoelectric power of a Ni base superalloy induced by elastic and plastic strain

“…The temperature of the austenite to martensite phase transition in the ferromagnetic shape memory alloy Ni 50 Mn 34 In 16 has been associated with a sharp change in the TEP and the thermal conductivity curves of the alloy [9]. TEP has proven to be an excellent tool to evaluate the carbon and nitrogen content in iron and steels [10][11][12][13], the critical temperature for the Fe 3 Al was marked by a sharp change in the slope of TEP vs. temperature plot and the phase boundary was also determined [14]. The TEP detected the dissolution of M 23 C 6 carbides in an X45Cr13 stainless steel [12].…”
