This webinar will describe the preparation of the sample, microscope examination of the sample, and analysis of the sample using international standards. https://www.leica-microsystems.com/science-lab/inverted-microscopes-for-grain-size-analysis-three-factors-to-consider/ Fri, 24 Jul 2020 13:21:00 +0000 MSc Bob Cowden https://www.leica-microsystems.com/11172 Metallography Quality Assurance Metallography – an Introduction This article gives an overview of metallography and metallic alloy characterization. Different microscopy techniques are used to study the alloy microstructure, i.e., microscale structure of grains, phases, inclusions, etc. Metallography developed from the need to understand the influence of alloy microstructure on macroscopic properties. The knowledge obtained is exploited for the design, development, and manufacture of alloy materials. https://www.leica-microsystems.com/science-lab/metallography-an-introduction/ Wed, 08 Jan 2020 12:43:00 +0000 Dionis Diez, PhD James DeRose https://www.leica-microsystems.com/27289 Metallography Metallographic Solutions from Leica Microsystems Watch this webinar to learn more about obtaining reliable and accurate metallographic results with Leica microscopes in terms of efficient analysis of non-metallic inclusions in steel as well as of alloy grains and phases.

The sample is contaminated after mechanical polishing. There are still some scratches on the surface. Grain structure is almost invisible. https://www.leica-microsystems.com/science-lab/surface-modification-of-znag-sample-sample-preparation-for-sem/ Mon, 17 Oct 2016 08:16:00 +0000 PhD Wolfgang Grünewald https://www.leica-microsystems.com/18215 EM Sample Preparation Cleaning of Smeared Sample Surfaces - Sample Preparation for SEM Application Note for Leica EM RES102 - Mechanical polishing of soft materials or hard / soft material combinations is tricky. The mechanical polishing process leads very often to smearing of the soft material. The smeared material covers the surface and fills small pores or holes. Grain structures, interfaces and other structural details can be masked. An additional ion milling step with milling angles between 10° C and 15° C with respect to the sample surface can remove or reduce the contamination. https://www.leica-microsystems.com/science-lab/cleaning-of-smeared-sample-surfaces-sample-preparation-for-sem/ Fri, 02 Sep 2016 06:49:00 +0000 PhD Wolfgang Grünewald https://www.leica-microsystems.com/18209 EM Sample Preparation Ceramics - Sample Preparation for TEM Application Note for Leica EM RES102 - Ceramic samples are mostly very brittle, and are therefore very difficult to thin mechanically to a low starting thickness for ion beam milling. The ion beam milling of insulators often leads to static charging of the surface of the sample. This, in turn, reduces the sputter rate. When using the Ti standard holder (standard TEM holder), however, sufficient secondary electrons are created by the ion beam also falling on the sample holder to largely compensate for the static charging. https://www.leica-microsystems.com/science-lab/ceramics-sample-preparation-for-tem/ Mon, 15 Aug 2016 18:46:00 +0000 PhD Wolfgang Grünewald https://www.leica-microsystems.com/5122 Metallography Quality Assurance Metallography with Color and Contrast The examination of microstructure morphology plays a decisive role in materials science and failure analysis. There are many possibilities of visualizing the real structures of materials in the light microscope. The image samples shown in this article demonstrate the information potential of some of the techniques used. https://www.leica-microsystems.com/science-lab/metallography-with-color-and-contrast/ Tue, 30 Aug 2011 22:00:00 +0000 Ursula Christian, Prof. Dipl. Wirt. Ing. Norbert Jost https://www.leica-microsystems.com/5116 Metallography Quality Assurance Steel – the All-Rounder That Has to Pass Many Tests Steel is a real all-rounder. However, each application requires a specifi c sort of steel grade. Without steel there would be no Olympic stadiums, wind energy plants, bridges, skyscrapers, trains, planes, cars, razor blades or knives for medical and home use – at least, not of the quality and design we know today. Buderus Edelstahl GmbH in Wetzlar, Germany is one of the world’s top producers of special steel. https://www.leica-microsystems.com/science-lab/steel-the-all-rounder-that-has-to-pass-many-tests/ Wed, 28 Apr 2010 22:00:00 +0000 Dipl. oec.-troph.
