Powder metallurgy enables the production of dense, fine-grained alloys with high purity and a uniform microstructure with minimal material losses. Pressing and sintering minimizes material loss, which reduces raw material costs and at the same time allows good control over the alloy composition. The targeted selection and mixing of the powders allows precisely defined material properties, even for difficult-to-mix systems such as TZM (molybdenum-titanium-zirconium-carbon). The method is also very well suited to the mass production of small to medium-sized components of the same geometry with narrow dimensional deviations.    <\/span><\/strong><\/p><p class=\"whitespace-normal\"><strong><span style=\"font-family: 'TT Commons Pro',sans-serif;\"><a href=\"https:\/\/www.linseis.com\/en\/wiki\/advancing-additive-manufacturing-with-thermal-analysis\/\">Additive manufacturing<\/a>, on the other hand, enables complex geometries, internal channels and bionic structures that would be impossible or very costly to implement using powder metallurgy. Additive processes such as laser powder bed fusion or binder jetting offer geometric flexibility that brings decisive advantages in the development of innovative component designs. Individual parts and small batches can be produced quickly and without expensive tools, which is ideal for research and prototype development. Complex or functionally integrated components are often significantly cheaper, as machining and assembly are no longer necessary and designs can be optimized without regard to milling or punching capabilities.   <\/span><\/strong><\/p><p class=\"whitespace-normal\"><strong><span style=\"font-family: 'TT Commons Pro',sans-serif;\">However, both processes face significant technical challenges. Defect and process control requires the utmost attention with both technologies, in particular the control of cracking and porosity with tungsten is problematic due to high melting points and brittle solidification. Material losses due to evaporation of low-melting alloy components such as nickel or iron can lead to uncontrollable alloy loss during melting. The need for post-processing, such as de-powdering, smoothing or post-heat treatment, usually remains, and components do not always achieve the density and mechanical quality of classic powder metallurgical components   <\/span><\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8783c45 elementor-widget elementor-widget-spacer\" data-id=\"8783c45\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-628c7d1 elementor-widget elementor-widget-spacer\" data-id=\"628c7d1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-168da18 elementor-widget elementor-widget-heading\" data-id=\"168da18\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Solutions for processing challenges<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8a53923 elementor-widget elementor-widget-spacer\" data-id=\"8a53923\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1657511 elementor-widget elementor-widget-text-editor\" data-id=\"1657511\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Pre-alloying powders in additive manufacturing significantly reduces evaporation and thus the loss of volatile alloying elements such as nickel or iron, as these are already homogeneously integrated and chemically bound within each individual powder particle (6).
