At MMTSL, we undertake a comprehensive range of Metallographic Testing, meticulously adhering to stringent ASTM and ISO standards.

Metallography has been the study of the microscopic structure of metals and alloys using optical metallographs, electron microscopes or other surface analysis equipment. As materials have evolved, metallography has expanded to incorporate materials ranging from electronics to medical implants. By analysing a material’s microstructure, its performance and reliability can be better understood. Thus metallography is used in new materials development, incoming inspection, production and manufacturing control, and for failure analysis; in other words, product reliability.

Metallography or microstructural analysis includes, but is not limited to, the following types of analysis:

➢Grain size

➢Porosity and voids

➢Phase analysis

➢Dendritic growth

➢Cracks and other defects

➢Intergranular attack (IGA)

➢Coating thickness

➢Inclusion size, shape and distribution

➢Case Depth

➢Weld and heat-affected zones (HAZ) microstructures

➢Identification of deleterious inter metallic phases such as sigma

➢Graphite nodularity

➢Carburizing and Decarburization thickness

➢Nitriding thickness

➢Sensitization

➢Flow-lines in forgings
