CHEMICAL PHYSICAL AND DETERIORATION CHARACTERISTICS

Electron Spectroscopy:Some Basic Concepts1.1 Analysis of SurfacesAll solid materials interact with their surroundings through theirsurfaces. The physical and chemical composition of these surfaces determines the nature of the interactions. Their surface chemistry will influence[r]

2.1. IntroductionIn this chapter, the material with which the steel detailer is concerned, i.e.structural steel, will be considered. It is vital that detailers should be familiarwith the characteristics and properties of steel.Steel is a man-made metal derived from iron, which is its m[r]
