Karl Dahm - Callaghan Innovation (TiTeNZ)

New Opportunities for Titanium parts made in New Zealand

Titanium has long been recognized as having many properties superior to ferrous alloys but has been beleaguered by high cost and difficulties in manufacturing. The MBIE-funded TiTeNZ project is developing powder metallurgical (PM) approaches to promote the wider adoption of titanium parts in NZ. By using these PM methods, the advantages of titanium (high strength/weight, corrosion resistance) can be utilised with a reduced cost penalty compared to commonly used engineering alloys. This presentation will highlight the properties of PM titanium (especially compared to stainless steel) and highlight the possibilities for high performance parts.

Karl Dahm is a Principal Scientist in Callaghan Innovation’s Advanced Materials Group. He leads the Metals & Ceramics Team whose main research focus is helping NZ companies develop innovative metallic and ceramic products using powder-based manufacturing processes. Karl has 20 years research experience in performance and properties of engineering materials.
