Fig. 2 Microstructure of as-cast Au22%Al showing the “purple plague,” AuAl2 intermetallic (reddish), surrounded by the Al-AuAl2 eutectic after polishing to a 1 lm finish. Magnification bar is 50 lm long. Fig. 1 Microstructure of a porous high-carbon steel powder metallurgy specimen infiltrated with copper showing the natural color of the copper, which is easier to see when the steel has been ti...
متن کاملMetallography of Aluminium alloys
This lecture aims at providing a survey of the metallographic techniques available for the examination of aluminium and its alloys. The information must be sufficient to be sure that the students and the users are able to choose the most suitable technique to solve their problems in the examination of samples. The lecture should contain a direct understanding of the main problems in the metallo...
متن کاملPolarized light microscopy.
Polarized light is the light in which all the rays vibrate in one plane. A polarizing microscope has two disk accessories. They are made up of polarizing plastic that allows light vibrating in one plane to pass. One of them is called a polarizer (placed below the condenser). Another similar disc is placed in the top part of the microscope and cuts off all the light vibrating in a perpendicular ...
متن کاملPolarized light reflectometer.
The modulated reflected and nonreflected light fluxes, measured as the azimuth of incident linearly polarized light is varied, yield the absolute reflectances R(p), and R(s), of a dielectric or semiconductor surface. Application to a reflective Si detector determines the refractive index and thickness of a SiO(2) film on the detector surface.
متن کاملInteraction Matter-Polarized Light
This chapter presents the process of interaction of light, mainly in the xray range, with matter. The subject is introduced by some experimental evidences of x-ray absorption, emission or scattering by different kinds of material. The ways of describing the electromagnetic wave field are then briefly presented before developing its interaction with an electron in an atom. This process is then a...
