CermeTi® Properties and Microstructure
Dynamet's uses acicular TiC and TiB2 as particulate additives for their composites. The TiB2 particles react with the titanium in-situ, transforming the particulate titanium diboride (TiB2) to titanium monoboride (TiB) needles.The CermeTi-C MMC consists of a particulate dispersion of TiC in a matrix of Ti-6Al-4V while CermeTi-B consists of TiB in a matrix of Ti-6Al-4V.
