Question: a brinell hardness measurement is made on a ductile iron...

Question details

A Brinell hardness measurement is made on a ductile iron (120-90-02, Oil-quenched) usinga 10-mm-diameter sphere of tungsten carbide. A load of 3,000 kg produces a 3.52-mm- diameter impression in the iron surface. Calculate the BHN of this alloy. (The correct units for the Brinell equation are kilograms for load and millimeters for diameters.) a. b. Predict the tensile and yield strengths
