- 1. This specification table shall be treated as a general guideline for students and Teachers. The actual distribution of marks in the question paper may slightly vary from above Table.
- 2. Ask the questions from each topic as per marks weightage. Numerical questions are to be asked only if it is specified. Optional questions must be asked from the same topic.
- 10. SUGGESTED STUDENT ACTIVITIES Other than the classroom and laboratory learning, following are the suggested student-related cocurricular activities which can be undertaken to accelerate the attainment of the various outcomes in this course: Students should conduct following activities in group
- 1. Organize field trip to companies or research facilities involved in alloy steel.
- 2. Analyze the microstructure of various alloy steels and stainless steels.
- 3. Compare properties and applications of different alloy steels.
- 4. Assign case studies that explore the application of alloy steels in industry.
- 11. SUGGESTED SPECIAL INSTRUCTIONAL STRATEGIES (if any) These are sample strategies, which the teacher can use to accelerate the attainment of the various outcomes in this course: a) Massive open online courses (MOOCs) may be used to teach various topics/sub topics. b) Guide student(s) in undertaking micro-projects c) ‘L’ in section No. 4 means different types of teaching methods that are to be employed by teachers to develop the outcomes. d) About 20% of the topics/sub-topics which are relatively simpler or descriptive in nature is to be given to the students for self-learning, but to be assessed using different assessment methods. e) With respect to section No.10, teachers need to ensure to create opportunities and provisions for co-curricular activities. f) Guide students on how to address issues on environment and sustainability. g) Encourage students to read codes and standards.

- 12. SUGGESTED MICRO-PROJECTS Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project are group-based. However, in the fifth and sixth semesters, it should be preferably be individually undertaken to build up the skill and confidence in every student to become problem solver so that he/she contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three. The micro-project could be industry application based, internet-based, workshop-based, laboratorybased or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry- oriented COs. A suggestive list of micro-projects is given here. This has to match the competency and the COs. Similar micro-projects could be added by the concerned course teacher:
- 1. List the limitation of plain carbon steel.
- 2. Prepare reports of need of alloy steel for various industrial applications.
- 3. Prepare chart of various alloying elements and effects of their addition on properties of steel.
- 4. Collect samples of tools, check their chemical composition and observe their microstructure.
- 5. Collect samples of stainless steels, check their chemical composition and observe their microstructure.
