The hardness is calculated from the test force and the indentation diagonal. The method is standardised in DIN EN ISO 6507.<\/p>\n<p><strong>Practical relevance:<\/strong> The Vickers method can be used universally &#8211; from soft metals to high-hardness steels &#8211; and is also suitable for thin <a class=\"tc-inlink\" href=\"\/en\/materials-engineering\/coating-technology-processes-and-applications\/\">coatings<\/a> or surface layers. Results are given as HV values together with the test force and dwell time (e.g. HV10). Precise specimen preparation and optical evaluation are decisive for reproducible results.<\/p>\n<p><strong>Decision-making perspectives:<\/strong><\/p>\n<ul>\n<li><strong>Technical decision-makers:<\/strong> Control of heat treatment, surface hardening and <a class=\"tc-inlink\" href=\"\/en\/home\/welding-brazing-soldering\/weld-seam-testing\/\">weld seams<\/a>.<\/li>\n<li><strong>Purchasing\/project management:<\/strong> Specification of permissible hardness ranges in accordance with material standards.<\/li>\n<li><strong>Science:<\/strong> Correlation of hardness with microstructure and tensile strength.<\/li>\n<li><strong>Insurance\/law:<\/strong> Documented verification of mechanical properties in the event of quality deviations.<\/li>\n<\/ul>\n<p><strong>Typical testing or verification methods:<\/strong> Vickers hardness testing (macro and micro hardness), <a class=\"tc-inlink\" href=\"\/en\/calibration-metrology\/\">calibration<\/a> with reference hardness blocks, hardness profile testing.<\/p>\n<p><strong>FAQ:<\/strong><\/p>\n<ul>\n<li>When is Vickers hardness testing preferred?<\/li>\n<li>For thin coatings, small specimens or when a universally comparable hardness value is required.<\/li>\n<\/ul>\n<\/div>\n","protected":false},"author":0,"featured_media":0,"template":"","encyclopedia-tag":[],"class_list":["post-3198","encyclopedia","type-encyclopedia","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/encyclopedia\/3198","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/encyclopedia"}],"about":[{"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/types\/encyclopedia"}],"wp:attachment":[{"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/media?parent=3198"}],"wp:term":[{"taxonomy":"encyclopedia-tag","embeddable":true,"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/encyclopedia-tag?post=3198"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
