RATIONALE, , With the advances made in the field of material science millions of materials are now, available to cater various need of mankind. These needs and service conditions dictate the, properties to be developed in the materials therefore the subject mechanical engineering, materials has attracted lot of attention. Materials like ferrous and non ferrous metals, polymer., ceramics and composites are widely used in verity of engineering applications. This course, deals with these materials along with advance materials. their metallurgical considerations., heat treatment processes. structure property relationship and applications. This course will, enable diploma engineering students to identify variety of material and their selection for, various applications., , 2, COMPETENCY, The aim of this course is to help the student to attain the following industry identified, competency through various teaching learning experiences:, , e Use relevant mechanical engineering materials in different applications., , & COURSE OUTCOMES (COs), The theory, practical experiences and relevant soft skills associated with this course are to be, taught and implemented, so that the student demonstrates the following industry oriented, COs associated with the above mentioned competency:, a. Identify properties of materials., Select relevant ferrous materials for mechanical components., Select relevant cast iron for the engineering application., Use non-ferrous metals for mechanical components., Suggest relevant advanced materials for mechanical components., Select relevant heat treatment process., , meeaog, , 4, TEACHING AND EXAMINATION SCHEME, , ae Examination Scheme, Credit Theory Practical, L |r| p {eet Paper |__ESE PA Total ESE PA Total, Hrs. |Max |Min | Max |Min | Max| Min| Max | Min | Max | Min | Max | Min, 3 | -]2 5 2 |70*#*] 28 | 30* |} 00 | 100 | 40 | 25# 10 25 10 50 20, , , , , , , , , , ():Online Exam; (*): Under the theory PA, Out of 30 marks, 10 marks are for micro-project, assessment to facilitate integration of COs and the remaining 20 marks is the average of 2, tests to be taken during the semester for the assessment of the cognitive domain UOs required, for the attainment of the COs., , Legends: L-Lecture; T — Tutorial/Teacher Guided Theory I ra, ESE - End Semester Examination; PA - Progressive Assess), , Reeitic al; C — Credit,, , , , , , MSBTE - Updated on 11.10.2018 Page 1 of 9

A suggestive list of PrOs is given in the above table. More such PrOs can be added to, attain the COs and competency. A judicial mix of minimum 12 or more practical need to be, performed, out of which, the practicals marked as ‘*’ are compulsory, so that the student, reaches the ‘Precision Level’ of Dave’s ‘Psychomotor Domain Taxonomy’ as generally, required by the industry., , ii.

Follow ethical Practices., , The ADOs are not specific to any one PrO, but are embedded in many PrOs. Hence. the, acquisition of the ADOs takes place gradually in the student when s/he undertakes a series of, practical experiences over a period of time. Moreover, the level of achievement of the ADOs, according to Krathwohl’s “Affective Domain Taxonomy’ should gradually increase as planned, below:, , e ‘Valuing Level’ in 1“ year, , © ‘Organizing Level’ in 2"! year, , © ‘Characterizing Level’ in 3" year,, , a MAJOR EQUIPMENT/ INSTRUMENTS REQUIRED, The major equipment with broad specification mentioned here will usher in uniformity in, conduct of experiments. as well as aid to procure equipment by authorities concerned., , , , , , , , | s. : : ae fu a, No Equipment Name with Broad Specifications |, “1 | Metallurgical Reflected light Microscope Vv, 30W halogen’ |, rg) Pp |, , Light.200x magnification.191x126x100 mm specimen stage ,Size With 100 |, | mm travel |, 2 Slitting Machine- Slitting width- standard 300 mm or extensible.
