The metal industry has begun to use X-ray Diffraction (XRD)as a reliable analysis of trace elements in the production of new and hybrid metals. It is possible because XRD enables metal manufacturers, to control the composition of alloys and the final product for suitability of its intended purpose. XRD is also used to monitor phases and compounds in the metals or in the intermediate products so that process is better optimised.
Metal Binding Study with XRD
Metals and alloys have high melting temperatures because of the heavy binding between the atoms. There are a variety of applications for metals and alloys.Due to the importance of these materials a study of their binding interactions can be carried out with XRD analysis. XRD can help to develop improved metallic materials so as to give a technological edge. Metals offer various combinations of properties and their versatility gets a boost when properties are varied with just a change in their microstructure. A number of alloys can be blended to form hybrid metals that are stronger, more durable, reliable, more cost-effective and suited for its intended use rather than pure metals. Therefore, X-ray diffraction or XRD has become an important method for designing new materials that can be used in extreme operating conditions.
XRD for Steel
X-ray diffraction can predict process behaviour, energy consumption and the quality of the final steel that is produced. XRD becomes the main tool that can quantify iron phases in ores, sinter, steel, slag and direct reduced iron. XRD analysis is, therefore, preferred over wet chemical techniques that are slow and labour intensive and for characterisation of materials in the production of iron and steel. XRD can help to measure residual stress in metals through its non-destructive method and it offers a most accurate analysis and so helps in preventing structural failure.
XRD for alloy classification
X-ray diffraction is now used routinely in many laboratories to counter-check the results of other methods of examination and analysis. In fact XRD is used extensively to classify alloy types and systems with the help of x-ray crystal analysis. XRD is used to determine the mechanism that forms an alloy as different reflection patterns of alloys can be studied. This analysis method is also used to determine the miscibility of alloys including their limits and also the solid-phase boundaries of several component alloy systems. XRD makes this possible because the X-ray diffraction patterns of ally constituents can be co-related.
Building material testing
XRD can be used to analyse the effects of twisting and bending on building materials like strips and wires. It is also used to check any deformation or distortion caused by rolling and shaping in metal strips. XRD can help to determine if there is any strain in the structure of a weld or in the area around the weld. It is also possible to detect the reasons as to why malleable iron becomes brittle and to understand how the brittleness can be removed so construction material remains durable and strong.
