There are so many ways and means to learn the physical properties of the materials. You could do so in the chemical laboratories by allowing them to react with so many different kinds of elements. The properties of those are already known from previous analysis and hence they react with the material under testing to observe and note down the fresh changes that occur. The amount of pressure that a material can withstand without any deformity in its internal composition is one of the key mechanical strength of the material. All these tests could be done without any solution or acid in the lab. Yes, XRD analysis is the physics methods, which are involved for the study. X-rays are the key tool, which are allowed to incident upon the material for testing. Scattering of the waves are noted for identifying the crystal structure inside. Elastic scattering techniques and nonelastic scattering techniques are there when it comes to incident the light upon the crystals for XRD analysis. You could not restrict this technique to physics alone. The study in-depth gets into the metallurgy studies in the mechanical engineering field. Especially production engineers are bound to have a basic understanding of these concepts to effectively govern the production rates and plan accordingly. Finite element analysis a very important and profound field of engineering design includes the study of these techniques as well. They do use the technique to design the components for new models. Prototype modeling techniques are analyzed and could be tested prior to their making by clear analysis of their internal strength through these techniques. Without having to break or shear a material you are given a chance to study and analyze the internal composition of the material especially metals by using this XRD analysis. This is the reason all the Non-destructive metal testing studies will have a subject separately allotted for this studies. You need to poses a lot of knowledge on fundamentals light theory and behavior from physics to understand the processes in detailed fashion. X-ray Wizards is a XRD analysis contract service testing lab specializing in x-ray diffraction (XRD). (http://www.x-raywizards.com)
