almosila Posted December 24, 2005 Share Posted December 24, 2005 I have qustion about that thing...... " A brinell hardness measurment is made on a ductile iron (air quenched) using a 10 mm diameter sphere of tungsten carbide. A load of 3000 kg produces a 3.91 mm diameter impression in the iron surface. Calculate the brinell hardness number of this alloy? Link to comment Share on other sites More sharing options...
DV8 2XL Posted December 27, 2005 Share Posted December 27, 2005 The brinell hardness is calculated by dividing the load by the area of the curved surface of the indention, (the area of a hemispherical surface is arrived at by multiplying the square of the diameter by Pi and then dividing by 2) Link to comment Share on other sites More sharing options...
