Many industries and government agencies are vigorously developing metal additive manufacturing (AM) practices. The efforts to move toward qualified processes, materials, and parts often still conflict with unexpected observations that impede the rapid insertion of AM into service. These unexpected findings can originate in microstructural details that require advanced microscopy solutions.
This webinar highlights examples of electron microscopy findings for common and often unwanted situations affecting metal powders and additively manufactured samples.
Attendees will learn about how:
• Inclusions in powder particles can re-emerge in additively manufactured samples, though they are often only detectable with electron microscopes
• Titanium-based alloy powders are commonly reused even though oxygen content increases
• Detailed microscopy studies reveal local oxygen enrichment along transformed beta phase in Ti-6Al-4V
• Hot cracking, microstructural transitions from thin to thick sections, and heat-treatments’ benefit from in-depth microscopy work in 17-4PH stainless steel
These examples demonstrate the need for comprehensive microscopy approaches and the overall value for AM advancement.
