After passing the course, the student should be able to:
The course consists of twelve (12) 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 must have understanding of materials science, at a level that allows them to execute their chosen project. Prior knowledge of powder metallurgy is advantageous but not essential.
None required.
There is no compulsory course literature for this course.

Extensive use shall be made of the Learning Management System. Additional content will be published there and it is recommended that you read the course page on the Learning Management System regularly throughout the course.
None required.
No specialist software will be used in this course, except wen you perform experimental work in the lab exercise (where the software is available).
Students at KTH with a permanent disability can get support during studies from Funka:
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.
The section below is not retrieved from the course syllabus:
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.
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.
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.
Both grading criteria must be passed to pass the laboratory execise:
Criterion | ||
Participation: the students attended and actively took part in the lab session. | ||
Report: the overall quality of the report |
Criterion | |||||
Main topic: this will take approximately 5-6 pages and will include one of the following types of powder technology:
|
30 Pts | 24 Pts | 16 Pts | 8 Pts | 2 Pts |
Secondary topic: this will take approximately 1-2 pages and is another of the three topics listed in the "main topic":
|
10 Pts | 8 Pts | 4 Pts | ||
Sustainable development: 1-2 pages answering the questions set i your assignment that deal with the area of sustainable development, including health and safety. | 10 Pts | 8 Pts | 4 Pts | ||
Citations: inclusion of appropriate citations for any information you include that is not found in the course material. | 4 Pts | 2 Pts | 0 Pts | ||
Language and figures: the quality of language in your report, as well as the clarity and usefulness of any images, graphs, tables, etc. you include.
You should present graphs, tables, images, etc. if they improve the quality of your report, but you do not need to do so to achieve the top grade, as long as you present information in the most appropriate way in your report. In other words, if you choose to not use graphs, tables, images, etc. and it would make your report better if you did include them, you may lose points. If your report would not be improved by including images, graphs, tables, etc. then you will not lose points if you do not include them. |
6 Pts | 4 Pts | 2 Pts | 0 Pts |
The written exam shall take place on Canvas. The exam shallb e 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 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. One week after the final grades are posted to Canvas, results shall be submitted for entry to Ladok.
The question "The assessment on the course was fair and honest" was graded at 4.7/7.0. This was partly due to the changing nature of the assessmetn due to the Covid-19 pandemic. I will include new explanations about the assessments and try to improve the perception of fairness - I can assure students that the assessment is anonymous and fair between students. Opinion was divided regarding the home assignment and whether it was reasonable to expect students to do such an exericse and a written exam. I have decided to retain both this year to collect more opinions about their usefulness and fairness. Some responses were very positive about the assignments, which is why I have not removed them for 2021.
Following an excellent suggestion in the 2020 course evaluation, one of the debates in the second sustainable development lecture shall consider health and safety issues surrounding metal powder.
Students did not feel particularly strongly that they could collaborate with others, but I hope this shall improve naturally as we return to Campus. I shall try to increase the ampunt of group work of the debates and laboratory sessions.
One student requested more laboratory teaching. The original course plan included two labortory sessions per group, but we had to reduce the group sizes due to Covid restrictions, so we were forced to reduce the number of laboratory sessions to one. This year, with the reduction in restrictions, we shall return to larger groups with two sessions.
