STUDY OF M23C6 PRECIPITATION IN A 45Ni-35Cr-Nb ALLOY
2019
Acta Metallurgica Slovaca
<p class="AMSmaintext">The 45Ni-35Cr-Nb alloy, commonly known as ET45 micro, produced in the form of centrifugally cast tubes, was studied by means of optical microscopy after aging treatments at 1073 and 1173 K for different times. A description of M<sub>23</sub>C<sub>6</sub> secondary carbides precipitation phenomenon was made as a function of time. The purpose of carrying out a kinetic study of the precipitation of this phase is to be able to calculate the activation energy required for
