Tool of Modern Man2000 AD

Made of metal, plastics, electronic materials, etc.Manufactured using tremendous scientific efforts

Tool of Primitive Man200,000 BC

Made of stone (a ceramics !!)Collected directly from nature

Without materials, there is no engineering !!

P f i f i l d ll i l i i l

Profession of mechanical, civil and other engineers involves‘engineering with materials’

i.e., they use materials in their creation

Profession of materials and metallurgical engineers involves‘engineering of materials’

i.e., they engineer materials to satisfy the needs of others
