Unformatted text preview: hardness of the microstructures while decreasing ductility. Martensite has carbon interstitials in the crystal structure and is the strongest, hardest, and most brittle. Observed trends in mechanical properties data The strength of the specimens (both tensile and yield strength) increases as the isothermal transformation temperature decreases. Hardness increases as the heat treatment temperature decreases. The youngs modulus should be constant because it is an intrinsic property of the metal and not dependent on the heat treatment. Observed trends in mechanical properties data Ductility increases as the treatment temperature increases. This was seen by looking at the percent reduction in area and percent elongation. Impact energy increases as the ductility increases. All our results followed the expected trends....
