Research in absorbable magnesium has become hugely popular, with groups around the world looking at bespoke biomedical alloy compositions and processing routes. However designing alloy chemistry and thermomechanical processing is only half the development process to producing a successful commercial alloy. A manufacturing route which answers the demands of the alloy’s chemistry and processing design as well as economic models and importantly risk must be created to ensure commercial viability and patient safety.
During scale up operations, certain alloys which show outstanding mechanical properties were actually highly unstable during casting because of cracking issues not seen on small diameter billets. Another alloy series had very tight parameters for extrusion in order to achieve the properties including a very low extrusion ratio. This meant the economics and ability to hit dimensional specifications was incredibly difficult. This presentation details the steps taken to bring research ideas to a full industrial process.
