Materials Science and Engineering III

Materials Science and Engineering III
type: Vorlesung (V)
semester: WS 19/20
time:

The lecture is held on Tue 09:45 - 11:15 am in 30.41 Chemie-Hörsaal Nr. 3 (HS3) and Thu 2:00 - 3:30 pm in 10.91 Redtenbacher HS. Further information will be provided in the lecture and via ILIAS.

lecturer: Prof. Dr.-Ing. Martin Heilmaier
Dr. Karl-Heinz Lang
sws: 4
lv-no.: 2173553
Notes

Properties of pure iron; thermodynamic foundations of single-component and of binary systems; nucleation and growth; diffusion processes in crystalline iron; the phase diagram Fe-Fe3C; effects of alloying on Fe-C-alloys; nonequilibrium microstructures; multicomponent iron-based alloys; heat treatment technology; hardenability and hardenability tests.

learning objectives:
The students are familiar with the thermodynamic foundations of phase transformations, the kinetics of phase transformations in the solid states (nucleation and growth phenomena), the mechanisms of microstructure formation and microstructure-property relationships and can apply them to metallic materials. They can assess the effects of heat treatmens and of alloying on the microstructure and the properties of iron-based materials (steels in particular). The can select steels for structural applications in mechanical engineering and subject them to appropriate heat treatmens.


requirements:
Basic knowledge in materials science and engineering (Werkstoffkunde I/II)


workload:

regular attendance: 53 hours
self-study: 187 hours

Prerequisites

Basic knowledge in materials science and engineering (Werkstoffkunde I/II)

Aim

The students are familiar with the thermodynamic foundations of phase transformations, the kinetics of phase transformations in the solid states (nucleation and growth phenomena), the mechanisms of microstructure formation and microstructure-property relationships and can apply them to metallic materials. They can assess the effects of heat treatmens and of alloying on the microstructure and the properties of iron-based materials (steels in particular). The can select steels for structural applications in mechanical engineering and subject them to appropriate heat treatmens.

Exam description

The assessment consists of an oral exam (30-40 min) taking place at the agreed date (according to Section 4(2), 2 of the examination regulation). The re-examination is offered upon agreement.
