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 non-mandatory lectures and two mandatory laboratory session for each student.  Some of the lectures are pre-recorded and distributed through the online Learning Management System, whil eothers are in-person. Students shall be informed about the type of lecture as fas as possible in advance of the scheduled date and time, although in-person lectures may be changed to digital or pre-recorded lectures at short notice.

Students are expected to perform a home assignment lasting approximately 20 hours at the end of the course.  Information will also be distributed through the online learning platform for students to study in their own time.  There will be a written 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, even though they are not all mandatory.

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

The home assignment 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 home assignment, laboratory report and examination.  This is intended to provide students with sufficient opportunity to demonstrate their knowledge and practice different forms of communication.

The following table is correct at the time of writing.  Students are encouraged to check the KTH Schema system for the latest course schedule.  If there is any disagreement between this information and that presented on KTH Schema, KTH Schema should be taken as correct.  Links to any scheduled Zoom meetings, such as those for digitally streamed lectures, shall be published on the schedule page of the Learning Management System as the course progresses.

Recommended prior knowledge

• Students should be aware of the basic theory of the heat transfer phenomena convection and radiation.
• Students should have understanding of materials science so they can understand a metal solidification process, including the associated thermodynamics.
• Prior knowledge of powder metallurgy is advantageous but not essential.

Equipment

None required.

Course literature

There is no compulsory course literature for this course.

Other sources of informaiton

Extensive use shall be made of the Learning Management System.  Additional content will be published there and it is recommended that you visit the course room on the Learning Management System regularly throughout the course.

None required.

No specialist software will be used in this course, except when you perform experimental work in the lab exercise (in which case the software is available in the lab).

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

Funka - compensatory support for students with disabilities

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 two labroatory exercise sessions and complete written questions.  Answers should be submitted to the exercise leader.  It is the responsibility of the students to arrange the deadline and submission method with the exercise leader during the exercise.  All sources of information 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 under controlled and monitored conditions.  The second part will consist of questions that require longer written answers.

Laboratory Exercise

Both grading criteria must be passed to pass the laboratory execise:

Home Assignment

Written exam

The written exam shall take place on the Learning Management System (Canvas). The exam shall be unsupervised and you may use any resources you choose. The exam shall be graded out of 40 points. Points shall first be awarded based on multiple choice answers give in the first section of the quiz. Once this section concludes, extended answer questions shall be revealed. The total of the points accumulated in these two parts gives the final score out of 40.

Should any student miss any deadline or mandatory exercise, they should discuss the matter with the examiner to agree an alternative examination exercise or task.

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. In such cases, the students should contact the examiner at the earliest opportunity. The examiner alone shall decide if an alternative task should be given to the student to replace the laboratory exercise, or if the student shall not be permitted to pass the labroatory exercise examination. Applications for a replacement exercise made after the session itself shall be considered only in exceptional circumstances and at the sole discretion of the examiner.

Results form all parts of the examinations shall be reported via the Learning Management System in the first instance.  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. One week after the final grades are posted to the Learning Management System, results shall be submitted for entry to Ladok unless disputed by the student.

• 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.

Since only two responses were received for the LEQ in 2021, there was no quantitative data on which to base changes for 2022.  Similarly, since only two students participated at KTH in 2022, no LEQ answers could be received.

Due to the fact that the main teacher shall be on parental leave during the first three weeks of the course, the sessions that take place in that time have been pre-recorded and made available according to the planned timetable on the Learning Managment System.

To mitigate the risk of cheating using artificial intelligence systems, the examination has been planned as a physical exam using a KTH computer room (in previous years, students took the exam at a location of their choosing).
