Teaching Method

Outline:

It is essential for engineers to understand the properties of metal materials related to daily life and industrial activities. Following the interpretation of phase diagrams, the preparation method and heat treatment of metal materials, especially steel, are taught in this course. The purpose of this course is to promote understanding of the characteristics and applications of steel materials.

Style:

Lectures and exercises by an instructor

Notice:

Students are required to submit a brief report at the end of every lecture/exercise. The contents of these reports will be reflected in the subsequent lecture/exercise.
Students who earned less than 60 points may be given a chance to sit for an extra exam upon request if there is a justifiable reason. 60 points will be given to those students who are assumed to be complete the course based on the results of such extra exam.
This is an obligatory course to obtain the license of Third grade maritime officer (Engine) at training schools designated by the Law of Maritime Officers as the subject on Engine Part 3 Material Engineering.
