5. HISTORICAL PERSPECTIVE

6. HISTORICAL PERSPECTIVE It Refers To The Evolution Of Materials And Their Usage Throughout Human History The Development Of Materials Has Been A Critical Factor In The Progress Of Civilizations, From The Stone Age To The Present Day Now, let us talk about some of the ages Stone Age Bronze Age Middle Age Industrial Revolution 20 TH Century Iron age

7. Stone Age Bronze Age Middle Age Industrial Revolution 20 TH Century Naturally occuring materials like stone, bone and wood were used. The discovery and use of bronze marked a significant advancement. Use of iron tools, structures and weapons Iron age Glass, Ceramics and textiles Mass production of materials like iron, steel and textiles. Rise of synthetic materials like plastics and polymers.

8. MATERIAL OF IMPORTANCE

9. MATERIAL OF IMPORTANCE DELHI IRON PILLAR THE IRON PILLAR WAS FORGED DURING REIGN OF FAMOUS GUPTA DYNASTY THE PILLAR IS ABOUT 7.4 M HIGH ALSO REFERRED TO AS ASHOKA IRON PILLAR THE ESTIMATED WEIGHT OF THE PILLAR IS 6511 KILOGRAMS THE CONSTRUCTION OF THE MASSIVE PILLAR IS A MARVELOUS ENGINEERING ACHIEVEMENT THE PILLAR IS RESISTANT TO CORROSION DUE TO FORMATION OF THIN PROTECTIVE PASSIVE FILM, AIDED BY RELATIVELY HIGH PHOSPHORUS CONTENT

10. OBJECTIVES

11. OBJECTIVES Analyze the effect of heat treatment on microstructure of steel sample Compare the change in the properties mentioned above and generate a report on it Performing heat treatment processes on steel sample. Analyze the effect of heat treatment on mechanical properties of steel such as yield strength, ultimate tensile strength and hardness etc

12. MATERIAL SELECTION

13. MATERIAL SELECTION DEPENDING UPON PROPERTIES AND COST WE HAVE DISCARDED SOME MATERIALS FROM ABOVE TABLE. SS 202 AND SS 304 HAVE VERY SLIGHT DIFFERENCE IN PROPERTIES BEFORE AND AFTER HEAT TREATMENT , SO THESE OPTIONS WERE REMOVED AISI 4140 AND AISI 1018 HAVE VERY HIGH YEILD STRENGTH , SO THESE MATERIALS ALSO NOT SELECTED FOR HEAT TREATMENT. EN 8 HAS MODERATE HARDNESS , YEILD STRENTH AND ELONGATION . COST OF EN 8 IS ALSO LESS THAN OTHER MATERIALS , SO THIS MATERIAL IS SELECTED FOR HEAT TREATMENT PROCESS

14. HEAT TREATMENT PROCESSES TO BE CONDUCTED Heat treatment processes are vital in enhancing material properties for durability and performance. From various techniques we will perform following process Annealing Quenching Normalizing

15. Annealing Quenching Normalizing Quenching Refers Specifically To Heat Treatments That Rely On Rapid Cooling Of The Metal To Achieve The Desired Physical Or Mechanical Properties Annealing, Treatment Of A Metal Or Alloy By Heating To A Predetermined Temperature, Holding For A Certain Time, And Then Cooling To Room Temperature in furnace Normalizing Is A Heat Treatment Process In Which We Heat The Metal To A Predetermined Temperature, Hold It There For A Certain Duration, And Then Cool It Back To Room Temperature In Air (Or Gas)

16. MECHANICAL PROPERTIES TO BE TESTED Yield strength- the stress limit after which the material starts to deform Plastically is known as the yield strength Ultimate tensile strength- it is the maximum stress that a material can withstand before breaking while it is subjected to tension. Hardness - hardness represents the resistance of material surface to Abrasion, scratching and cutting, hardness after gives clear indication Of strength. Microstructure - The microstructure of steel refers to the arrangement and distribution of the various constituents within the steel at a very small scale, typically at the microscopic level. It is a crucial aspect of steel's properties and performance, as it directly affects its mechanical, physical, and chemical characteristics. ​
