The detailed syllabus for Materials Structure and Properties B.Tech (R13) fourthsem is as follows<\/p>\n
OBJECTIVES:<\/strong><\/p>\n The subject introduces the correlation of properties of materials and their structure. It revises student\u2019s knowledge of crystal structure and phase diagrams of various alloy systems. The course not only covers metals, mainly ferrous and non-ferrous alloys, but also structures and properties of ceramics, polymers, elastomers and composites.<\/p>\n UNIT I : STRUCTURE OF SOLIDS \u00a0<\/strong> \u00a0 \u00a0[10 Hours] UNIT II : PHASE DIAGRAMS<\/strong> \u00a0 \u00a0\u00a0[10 Hours] UNIT III : FERROUS AND NON FERROUS MATERIALS \u00a0<\/strong> \u00a0\u00a0\u00a0[9 Hours]
