(R) Ultrasonic Inspection Titanium and Titanium Alloy Bar, Billet and Plate
|Publication Date:||1 July 2017|
This specification covers the procedure for ultrasonic inspection of wrought titanium and titanium alloy products 0.25 inch (6.4 mm) and over in cross-section (thickness) or diameter.
When specifically requested by purchaser, this specification may be used for metals other than titanium.
This procedure has been used typically for locating internal defects, such as cracks, voids, spongy areas, inclusions and other structural discontinuities, which may or may not be exposed to the surface, but usage is not limited to such applications.
Testing will normally be accomplished by a procedure utilizing straight beam longitudinal wave inspection with acceptance criteria specified in the Ultrasonic Quality classes as in Table 8 of this specification, but angle beam inspections accomplished by a procedure utilizing either refracted longitudinal or shear wave inspection may be used when agreed upon by purchaser and inspection source.
Round bar and billet may use AMS2628 techniques and equipment for billet over 4.5 inches, using the acceptance criteria of Table 8 of this specification.
