(a)
Interpretation:
From the following graph of heat treatment, The yield strength and tensile strength needs to be determined. The steel is used of 1050 steel with brinel hardness at least 330 and elongation at least 15%.
Concept Introduction:
Heat treatment takes place under metal operating procedures that sometimes also alter chemical physical characteristics. In the production of many other products, such as glass, heat treatments are also used. Heat treatment includes heating o rcooling to obtain a required outcome such as hardening or softening of a material, usually at extreme temperatures. Techniques for heat treatment include annealing.
(b)
Interpretation:
The tensile strength and yield strength obtained using 1080 steel under heat treatment process needs to be determined.
