Viewing Metallurgical Specimen and Inverted Metallurgical Microscopy
The science of metallurgy has been employed since the Paleolithic age where a small number of natural gold had been discovered in Spanish caves. From then on, metallurgy had its fair share in civilization and various cultures. The evolution of tools can be traced back as to how early civilization developed the different metals that they discover and utilize them as useful instruments.
Today the field of metallurgy cannot simply be underrated. Its contribution to mankind has definitely created a world of development taking into consideration the gradual growth of economy and advancement in technology.
In today’s modern world, the contribution of metallurgy has been recognized in various fields such as communications, farming, transportation, construction, food preservation and processing, biomedical applications, electrical power distribution, and aerospace.
However, before somebody can make use of metals, it is important to identify the extent of their usefulness based on their mechanical and chemical properties. Metals differ from each other based on the properties that they possess and each property has its own function and usefulness.
For instance, it is vital to identify the mechanical properties of metals such as resistance, hardness, strength, and ductility to show the capacity of metals to withstand certain factors that may contribute to its corrosion.
On the other hand, viewing metallurgical specimens using an inverted metallurgical microscope would mean identifying the chemical properties of metals to understand how they react with the different elements around them.
For example, metals can counter acid in a “single displacement” to produce aqueous salt solution and hydrogen gas. However, not all metals can be used to produce such result. Hence, it is important to identify the metals with chemical properties that will qualify for such process. This is because metals can undergo chemical reaction based on its composition. So for metallurgical studies, it is important to identify the chemical properties of a certain metal to provide the probability of achieving the desired chemical change.
Using Inverted Metallurgical Microscope
An inverted metallurgical microscope is specially designed to match the conditions of the contemporary metallurgical laboratories. The main feature of an inverted metallurgical microscope is the surface of the stage, which is flat and unobstructed providing no restriction on the height and dimension of the specimen.
The term inverted metallurgical microscope is derived from one of its feature. With metallurgical microscopes, you can view the bottom of the specimen because they are inverted. They also provide minor magnifications to permit sharper, brighter images merged with a “wide field of view.”
Significance
The importance of inverted metallurgical microscopy cannot simply be underrated. Metallurgists know that microscopic observation of the different properties of metals especially their chemical properties is important for them to know why metals and alloy, a combination of two metals or with another element, behave the way they do.
Moreover, metallurgists study the various activities of metals to understand how they will react with the other elements in the environment. For instance, they view metallurgical specimens using inverted metallurgical microscope to identify heat treatment on the component stages of alloys, the consequences or the upshots of temperature, and the crystallography or simply the composition of atoms in solids.
In this way, it will be easier for concerned individuals to identify metals and understand their biochemical and mechanical reactions.
Consider the behavior of the atoms of metals when exposed to oxygen. Why does rust appear? Of course we all know that metals are vulnerable to rust or the so-called oxidation.
Experts say that when chemical change takes place, the composition of the original substance is altered or rearranged. Producing a new element or compounds, the arrangements of the atoms are reshuffle in such a way that the by-product is entirely different with the original item.
Taking this into consideration, it will be easier for you now to understand why magnesium, for example, when exposed to oxygen will produce an exceptionally flame.
On the other hand, viewing specimens using inverted metallurgical microscopes may also refer to measuring electroplating and thin film coatings, grain size, surface defects, and inclusions.
So for general use or for specific applications like analysis of sand castings in iron metal foundries, study of prehistoric Stone Age artifacts and tools, measurement of thin films, identification and analysis of metallic grain microstructure, or simply the study of metallurgy, viewing metallurgical specimens and inverted metallurgical microscopy is essential. With this, the viability of metallurgical microscopes cannot simply be matched. Their contribution to the society is simply amazing.
