ISO 20160:2006 provides a catalogue of metallographic photomicrographs for the designation of microstructures of alpha+beta titanium alloys in the form of bars that are intended for the manufacture of surgical implants. ISO 20160:2006 is applicable to bars of diameter no greater than 100 mm or the equivalent.

Overview

ISO 20160:2006 - Implants for surgery - Metallic materials - Classification of microstructures for alpha+beta titanium alloy bars provides a standardized catalogue of metallographic photomicrographs for identifying microstructures of alpha+beta titanium alloys used to manufacture surgical implants. The standard applies to bars (transverse sections) up to 100 mm diameter (or equivalent) and is intended as a communication aid for typical morphological microstructural types (Annex A, micrographs A1–A24). ISO 20160:2006 reproduces and updates images originally published in the ETTC 2 brochure (Ti-6Al-4V representative) and notes that digital copies can alter image quality - printed ISO copies are recommended for comparison.

Key topics and requirements

Catalogue of reference micrographs: Annex A contains 24 ×200 magnification photomicrographs (A1–A24) showing typical alpha+beta titanium microstructures (transverse bar sections).

Scope: Applicable to alpha+beta titanium alloy bars intended for surgical implants; Ti‑6Al‑4V is used as a representative alloy but images are relevant to other alpha+beta alloys.

Identification procedure:

Prepare transverse metallographic sections of the bar.
Etch using suitable microetching techniques (guidance: apply ASTM E407).
Examine at ×200 magnification under bright-field optical microscopy and compare with Annex A images to designate the closest type (e.g., “Type A3”).

Etching guidance: The standard recommends etchant number 192; within the recommended concentration range, a routine solution found suitable is: 100 ml H2O + 2 ml HF (40% mass fraction) + 8 ml HNO3 (ρ = 1.4).

Classification notes:

The standard is descriptive, not prescriptive - it does not set mandatory microstructural acceptance criteria.
It includes both desirable and undesirable microstructures; selection of acceptable types must be agreed between supplier and user based on implant application and other material standards.
Some micrographs (A20–A24) were noted as unacceptable in earlier ETTC guidance.

Applications and users

ISO 20160:2006 is practical for:

Orthopaedic and medical implant manufacturers assessing incoming bar stock

Materials and metallurgical engineers documenting microstructure after processing (forging, heat treatment)

Quality inspectors and testing laboratories performing metallography for supplier qualification

Regulatory reviewers and R&D teams comparing microstructural morphology for implant safety and performance Use cases include incoming materials inspection, process control, failure analysis, and communication of microstructure in specifications.
