1.       Explanation for the use of metal powder

2.       Methods for metal powder production

3.       Powder properties and characterisation methods

4.       Handling of metal powder

5.       Process paths for production of components from metal powder

After passing the course, the student should be able to:

• Give example of and evaluate different process paths for production of metal powder
• Compare relevant methods to measure properties of powder and evaluate these for a given powder material and intended application
• Justify for possible changes in powder properties due to storing and handling and explain how this can be prevented or is mitigated
• Give example of and justify different process paths for production of PM components (components of metal powder)
• Explain which different generic properties a powder may depending on production process and justify for the suitability for a specific component manufacturing method
• Give example of components produced with powder metallurgy and justify why the PM process has been used in these cases

The course consists of sixteen (16) non-mandatory lectures and one mandatory laboratory session for each student (reduced from two laboratory sessions due to limitations on the number of students that can be in the laboratory at any one time due to Covid-19).  Students are expected to perform a project lasting approximately 20 hours during the course.  Information will also be distributed through the online learning platform for students to study in their own time.  There will be an exam after the end of the course.

The non-mandatory lectures provide information and discussion, which is complemented by the information uploaded to the online Learning Management System.  It is highly recommended that students attend all sessions.

The laboratory session provides practical experience and more information about powder characterisation.  Successful participation in the session is required to pass the course.

The project allows students to apply the knowledge they have gained from the course (and any prior training in powder metallurgy) to an industrial scenario and to assess the impact of technical choices on sustainable development.

Assessment of the project is by written project report, laboratory report and examination.  This is intended to allow students the opportunity to demonstrate their knowledge, practice three forms of communication

Students at KTH with a permanent disability can get support during studies from Funka:

Funka - compensatory support for students with disabilities

Please inform the course coordinator if you need compensatory support during the course. Present a certificate from Funka.

A, B, C, D, E, FX, F

• HEM1 - Home assignments, 3.0 credits, Grading scale: A, B, C, D, E, FX, F
• LAB1 - Laboratory work, 1.0 credits, Grading scale: P, F
• TEN1 - Written exam, 2.0 credits, Grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Home assignment (HEM1)

Each student shall be set a unique industrial scenario and required to provide a suitable response.  This response form the written report of the assignment.  This shall be submitted via the Learning Management System.  All sources of inforamtion may be used during the home assignment.

Laboratory work (LAB1)

Students shall attend one labroatory exercise session and complete written questions.  Answers should be submitted to the exercise leader.  It is the responsibility of the students to arrange the deadline and submissio nmethod with the exercise leader during the exercise.  All sources of inforamtion may be used during the home assignment.

Written exam (TEN1)

The written exam will take place in two parts.  The first part is a series of randomly selected multiple choice questions completed on the Learning Management System.  The second part will consist of questions that require longer written answers.  THese asnwers must be submitted via the Learning Managemetn System.  The answers can be handwritten, but the student is responsible for submitting the answers in a suitable format via the Learning Management System.  Submissions by email will only be accepted in exceptional circumtances.

All course notes and other soures of information are permitted during both parts of the written exam.

It is not permitted to raise an approved grade via a renewed examination.

It is possible to arrange a replacement exercise to replace the laboratory exercise if compelling reasons are provided to explain why it is not possible to attend the laboratory exercise on either occasion it is offered.

Results form all parts of the examinations shall be reported vie the Learning Management System.  This will include a breakdown of the individual grading criteria for the home exam and the multiple-choice and written answer parts of the examination.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

This is the first time this course has been offered.
