Ferrous & Non Ferrous Metal Testing हिंदी में पढ़ें

Grain Size:

A material’s grain size is important as it affects its mechanical properties. In most materials, a refined grain structure gives enhanced toughness properties to the metal and alloying elements are deliberately added during the steel-making process to assist in grain refinement.

Effective Case Depth Test:

This test helps in determining the depth to which the micro indentation hardness of the exterior portion of a part has been increased over that of the interior of the part.

Non-metallic Inclusion Content:

Non-metallic inclusions in steel are foreign substances. They disrupt the homogeneity of structure, so their influence on the mechanical and other properties can be considered. During deformation, which occurs from flattening, forging and stamping (metalworking). Stamping and non-metallic inclusions can cause cracks and fatigue failure in steel.

Segregation of carbides:

Carbide segregation to the boundaries of particles used in powder metallurgy to generate an article is eliminated through the use of a nickel-base alloy powder which coordinates carbon with the amount of Mo and W which can form detrimental amounts of undesirable carbides and with Cb, Ta, Hf and Zr which are strong and of desirable MC-type carbide.

Porosity Content Test:

This test is important for materials science, research and development, catalyst evaluation, exploration and production and many other applications.
