适用范围：This International Standard provides a catalogue of metallographic photomicrographs for the designation ofmicrostructures of alpha+beta titanium alloys in the form of bars that are intended for the manufacture ofsurgical implants. This International Standard is applicable to bars of diameter no greater than 100 mm or theequivalent.This catalogue of microstructures is intended to serve as an aid in the communication on general types ofmicrostructures of alpha+beta titanium alloy bars. The designation of the microstructures is based onmorphological appearance. Actual microstructures can also appear as a combination of the type ofmicrographs shown.This International Standard does not contain specific microstructural requirements. The catalogue includesphotomicrographs of desirable and undesirable microstructures that can develop during the processing ofalpha+beta titanium alloys. The selection of acceptable microstructures is subject to agreement under the consideration of implant application and relevant material standards.
