5、 RATIONALE AMS 4965J results from a Five Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers a titanium alloy in the form of bars, wire, forgings, and flash welded rings 4.000 inches (101.60 mm) and under in nominal diameter or least distance between parallel si
6、des and of stock for forging and flash welded rings. 1.2 Application These products have been used typically for parts which are machined after solution heat treatment and aging and are suitable for parts requiring high strength-to-weight ratios up to moderately elevated temperatures, but usage is n
7、ot limited to such applications. 1.2.1 Certain processing procedures and service conditions may cause these products to become subject to stress- corrosion cracking; ARP982 recommends practices to minimize such conditions. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the
8、 date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, t
