OVERVIEW

The lectures in this course focus on the application of modern metallurgy in various aspects of everyday life. Emphasis is placed on understanding how metallic materials interact with the surrounding environment, including during manufacturing, operation, and exposure to different environmental conditions.

To enhance student engagement, the classes incorporate case studies and interactive activities designed to foster curiosity and sustain attention.

These classes are specifically designed for students who have successfully completed the credits of Metallurgy 1 or an equivalent course.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to consolidate the knowledge of basis on steels, provide elements on non-ferrous metals copper-based and aluminum-based. They will be introduced notions relating to the evaluation of the castability of copper alloys, welding techniques and the use of steels as interconnectors of high temperature fuel cells. A part of the course will be devoted to the application of the science of metallic materials in the field of cultural heritage

AIMS AND LEARNING OUTCOMES

During the course, the student will:

• Gain knowledge about steel and its various types, including special steels.
• Understand the significance of alloying elements in iron-based alloys and their collective functions.
• Develop an awareness of special metallurgy and the associated methodologies.
• Gain insights into additive manufacturing techniques.
• Acquire the ability to effectively interpret technical sheets related to steels and metallic materials in general.

This field of knowledge is applicable to both profiles offered by the Master's degree program in Materials Science and Technology: Materials Scientists specializing in research and development, as well as those specializing in technologies.

PREREQUISITES

The student shall have followed Metallurgy 1 or equivalent teaching lessons.Prerequisite: The student is required to have completed Metallurgy 1 or an equivalent course.

TEACHING METHODS

The majority of lectures take place in the classroom with the active participation of industry experts. As a culminating experience of the teaching program, one credit is dedicated to practical and experimental activities. Additionally, a visit to a metallurgical company is planned towards the end of the course, providing students with real-world exposure and insights into industrial practices.

SYLLABUS/CONTENT

The course includes a recap of the fundamental knowledge in metallurgy, covering the strengthening methods used in steels such as alloying, cold hardening, ageing, and secondary hardening. It explores the influence of alloying elements on steel properties and characteristics. Detailed descriptions of various classified commercial steels are provided, ranging from micro-alloyed to highly alloyed steels, including HSLA, maraging, duplex, weathering, micro-alloyed, and Austempering. The course also covers stainless steels, powder metallurgy, and additive manufacturing techniques such as 3D printing. Additionally, an introduction to room temperature corrosion, high temperature oxidation, and related electrochemical measurements is provided. The course concludes with an introduction to non-destructive testing methods.

EXAMS

EXAM DESCRIPTION

Oral exam: 3 questions of 10 points each

ASSESSMENT METHODS

The exams is based on the discussions rising from a technical sheet about one of the steel kinds presented during the classes. The metallurgical properties, the effect of alloying elements and the practical applications are the three main topics threated  during the exam.
