JBM Metallurgical Microscope is one of the important tools for Metallurgist, it helps revealing the microstructure of the materials in details, which turn will help metallurgist to analyze the properties and behavior of the material under study.
Microscope World’s metallurgical microscopes have high magnification with reflected and transmitted light. Metallograph microscopes allow the user to view opaque items at high magnification. Specialty uses for metallurgical microscopes include use as measuring instruments for measuring thin films, electroplating coatings, grain size, surface inclusions, Decarburization, case depth, structures and defects. Our metallurgical microscopes are available in binocular and trinocular models with both upright, inverted and boom stand microscope systems. Have Infinitive Optical System which provides excellent optical functions. With the stable stand structure, advanced stage design and comfortable operation, it is widely used in institute and laboratory to observe and identify the structure of various metal and alloy.
Advantages of Microscope:
1. An inverted microscope gives you greater freedom than an upright one
2. Microscopes enable you to look at more samples in a shorter period of time
3. With an inverted microscope, you cannot crash an objective into the sample
4. Inverted microscopes save you time and money in sample preparation
5. An inverted microscope works in the same direction the world does.
Various Tests to be performed on Microscope Microstructure by ASM HAND BOOK VOL-9
· Metallurgical phases and microstructures found in steels and their effects on steel strength and hardness.
· How to use the iron-carbon phase diagram to predict the phases present in a steel alloy based on composition and temperature.
· Microstructure changes that occur in steel during heating and cooling and the resulting effects on strength and hardness
· Effects of cooling rate on the microstructure that forms when steel is quenched during through hardening heat treatment.
Grain Size by ASTM E 112-13 Metals, except in a few instances, are crystalline in nature and, except for single crystals; they contain internal boundaries known as grain boundaries. When a new grain is nucleated during processing (as in solidification or annealing after cold working), the atoms within each growing grain are lined up in a specific pattern that depends upon the crystal structure of the metal or alloy. With growth, each grain will eventually impinge on others and form an interface where the atomic orientations are different.
Inclusion Rating by ASTM E 45-13 Inclusions are nonmetallic particles embedded in the steel matrix. Chemical compounds of metals like (Fe, Mn, Al, Si, Ca etc) with non metals (O,S,N,C,H). An Inclusion is a mismatch with the steel matrix. Both may have different properties resulting in underied effect.
De-Carburization by ASTM E 1077-01 The term is typically used in metallurgy, describing the reduction of the content of carbon in metals (usually steel). Decarburization occurs when the metal is heated to temperatures of 700 °C or above when carbon in the metal reacts with gases containing oxygen or hydrogen.
