Mechanical Engineering

1) Identify the type of steel (alloy?) with valuessimilar to the following:
Modulus of Elasticity = 189.75 MPa
Ultimate Tensile Strenght (UTS) = 740.05 MPa
Cup Cone Fracture
Toughness = 4.84 MPa
2) Identify the type of treatedsteel(alloy?) with values similar to the following:
Modulus of Elasticity = 326.07 MPa
Ultimate Tensile Strenght (UTS) = 408.97 MPa
Cup Cone Fracture
Toughness = 140.91 MPa
My guess is that this one is some type of heat treatedsteel, the steel being the same type as 1) but I do not know how toidentify it.
3) Identify the type of brass (alloy?)with values similar to the following:
Modulus of Elasticity = 84.88 MPa
Ultimate Tensile Strenght (UTS) = 480.34 MPa
Diaginal, Rough Fracture
Toughness = 76.47 MPa
All of these values have been calculated from a TensileTest machine and by hand so there is room for error.

1 Since the ultimate tensile strength is very high for this type of steel it must be quneched and tempered hot rolled steel When looked in standard steel charts ASTM A514 Grade See Answer
