 The study examined the effect of different extrusion parameters on the mechanical and electrical properties of L2.3% Fe alloys. It found that increasing the billet preheat temperature prior to extrusion resulted in lower hardness values due to the formation of larger grains. Additionally, increasing the extrusion temperature led to lower hardness values while increasing the extrusion time had no significant effect. Furthermore, increasing the extrusion temperature also reduced the electrical conductivity of the material, but only when it was held at elevated temperatures for extended periods of time. Finally, the study showed that annealing the extrudate after extrusion improved its electrical conductivity. This article was authored by Ryohei Kobayashi, Tatsuya Funezuka, Tora Mayada, and others.
