Cement Clinker Preparation and Microscopic Examination

Cement Clinkers are an intermediate product in the production of Portland Cement, one of the key ingredients in the manufacturing of concrete. Microscopic examination and analysis of Clinkers is a Quality Assurance process that assesses the nature and quality of Clinker constituents. This Webinar will discuss the process of sample preparation, microscopic examination, and the assessment of Cement Clinkers.

Basic Metallographic Analysis of Welds

Dave Coulston discusses what benefits can be derived from the different weld examinations and how best to prepare welds for such analyses, as well as typical weld measurements and examples of automated hardness testing of welds.

Analysis of Carburized Steels by Glow Discharge Spectroscopy

Precise measurement of carbon in carburized steel can be challenging due to changing concentrations throughout the hardened case of a sample. Glow discharge spectroscopy (GDS) offers a repeatable ability to measure carbon in a region spatially discrete from organic carbon on the near surface and in the base material. The presentation includes comparisons to other measurements, relationships to microhardness measurements, and characterization of the materials with GDS compositional depth profiles and bulk analyses.

Metallographic Preparation and Analysis of Carburized Steel

Many steel components can benefit from surface hardening, which improves wear resistance while maintaining a part’s toughness. Surface hardening can be accomplished by nitriding, induction hardening, or even shot peening; but carburizing remains the most viable choice for many applications. In this webinar, Dave Coulston explains what carburizing is, how it is accomplished, and then describes the important chemical, metallurgical and mechanical property results of a carburizing treatment. This is followed by metallographic preparation of carburized steel and microscopic evaluation of the carburized layer.
