La Ciencia de los Materiales es una rama común de conocimiento a todas las ingenierías que no suele tener el peso que merece. No se transmite a los alumnos la importancia que tendrá en el desarrollo de su vida profesional. Todo está hecho de un material que debe cumplir con unas especificaciones y, sin eso, el desarrollo de productos y procesos...
