Mechanical Metallurgy Detailed Syllabus for B.Tech second year second sem is covered here. This gives the details about credits, number of hours and other details along with reference books for the course.
The detailed syllabus for Mechanical Metallurgy B.Tech 2016-2017 (R16) second year second sem is as follows.
B.Tech. II Year II Sem. L/T/P/C
Course Code: MM403ES 4/1/0/4
Course Objective: This course is primarily designed to develop the fundamental aspects of mechanics of deformation and fracture of materials by destructive testing.
Course Outcome: At the end of the course, the student will be able to identify and analyze the deformation mechanisms that occur in metals and alloys so that the metal forming operations can be easily understood.
UNIT- I Plastic Deformation in Metals and Alloys: Critical resolved shear stress. Defects in
crystalline materials Point defects and line defects. The concept of dislocation – Edge dislocation and screw dislocation. Interaction between dislocations, sessile dislocation, glissile dislocation, dislocation climb, Jogs, Forces on dislocations Energy of a dislocation. Frank Reed source, slip and twinning.
UNIT II Fracture: Elementary theories of fracture, Griffith’s theory of brittle fracture, Ductile
Fracture, Notch sensitivity. Hardness Test: Methods of hardness testing Brinells, Vickers, Rockwell, Rockwell superficial, Shore and Poldi methods, Microhardness test, relationship between hardness and other mechanical properties.
UNIT III Tension Test: Mechanism of elastic action, linear elastic properties. Engineering stress and
Engineering strain, True stress-strain curve. Tension Test and tensile properties, conditions for necking, effect of temperature and strain rate on tensile properties. Compression Test: Elastic and in elastic action in compression, compression Test. Impact Test: Notched bar impact test and its significance, Charpy and Izod Tests, significance of transition temperature curve, Metallurgical factors affecting the transition temperature, temper embrittlement. DBTT curve and its importance. Fracture toughness
testing – COD and CTOD tests.
