The hardness number may then be read directly from the scale.The indenter and the test load used determine the hardness scale that is used (A,B,C,etc).For soft materials such as steel alloys,soft steel,and aluminum alloys a 1/16 diameter steel ball is used with a 100-kilogram load and the hardness is read on the B scale.Nondestructive Evaluation Physics Materialsatoms bond,a metallic bond occurs.When an atom.Atom - The smallest particle of any element that still retains the characteristics of that element.All matter such as solids,liquids,and gases,is composed of atoms.has a nearly full electron shell,it will try to find electrons from another atom.Optical Emission Spectroscopy (OES) - AcurenOptical Emission Spectroscopy.Portable optical emission spectroscopy (OES),also known as Spark Testing,is a method of positive material identification (PMI).History shows numerous industrial incidents have occurred as a result of the inadvertent substitution of materials in piping systems,fittings,flanges,gaskets,bolting materials and other components.
