The properties of metals are determined by their metallurgy, and for applications such as medical use, these properties must be optimized. To achieve this, international standards specify the required microstructure. Two key standards for medical titanium materials are ASTM F136 and ISO 5832-3.

ISO 5832-3 defines microstructure classes with specific alpha and beta morphologies and phase distributions, detailed through micrographs. In contrast, ASTM F136 outlines microstructure requirements without specifying exact classes or providing micrographs, thus omitting precise details on alpha and beta phase distributions.

To illustrate this, consider the example of the color blue. ASTM F136 broadly accepts any shade of blue for medical applications. However, ISO 5832-3 specifies exact color codes, categorizing shades from Class Sr. No. A1 to A9, and thus sets rigorous microstructure requirements for medical grades. ASTM F136 lacks this level of detail and does not categorize shades of blue, merely stating that any blue is acceptable for medical use.

Therefore, adhering to the ISO 5832-3 standard is crucial for ensuring the precise microstructure requirements in Titanium materials needed for medical device manufacturing.
