as AXJ810-TH—with creep and
ignition resistance due to calcium
addition. The ongoing quest
to improve fuel economy in the
automotive sector will also continue
to generate renewed interest in
lightweight materials.
In the biomedical field,
thermomechanically processed
Mg is expected to find additional
applications external to the
body. The bioabsorbable BioMg
250 will now enter a sequence
of larger animal tests and
clinical studies leading to FDA
approval. Commercialization
of a bioabsorbable Mg alloy
that features the mechanical
properties of metals as well as
safe, predictable bioabsorption
rates will benefit the orthopedic
medical practice.
