  • AWP is hosting during the winter semester 2019-2020 María Guadalupe Gómez, a visiting student of Industrial Engineering at the Universidad Tecnológica Nacional in Santa Fe, Argentina (UTN – FRSF). Guadalupe is currently performing her final undergraduate thesis for the company Metalurgica Galcom, a steelmaker which manufactures truck turntables and other bearing components. The project deals with the evaluation of a reengineering process in the company in terms of energy costs and product quality.
  • Our former DAAD guest student at AWP, Adriana Eres Castellanos, has won the first prize of the 2019 FEMS Master Thesis Award Competition bestowed by the Federation of European Materials Societies, for her work entitled: “Effect of ausforming on the bainitic transformation in medium carbon steels”. Adriana Eres Castellanos was advised by Lucia Morales-Rivas on the crystallographic approach to the mentioned topic during her stay at TU-Kaiserslautern between February and April 2019, holding a research short-stay DAAD grant.
