galvanized steel, among others [1, 2]. AISI 4340 is classified as a medium-carbon and multiphase steel. According to the heat treatment to which it is subjected, its microstructure can consist of ...

Here we use multiscale, advanced characterization to better understand the structural and chemical evolution of AISI 4340 steel after quenching and tempering (Q&T), including the role of quench rate ...
