5、NALE AMS 4967J is 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, flash welded rings, and stock for forging, heading, or flash welded rings. 1.2 AppLication These products have been used typically
6、for parts to be rough machined prior to solution and precipitation heat treatment and for parts, such as pressure vessels and other aerospace structures, requiring high strength-to-weight ratios at or near room temperature, but usage is not limited to such applications. 1.2.1 Certain processing proc
7、edures 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 date of the purchase order forms a part of this specification
8、 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, the last published issue of that document shall apply. 2.1 SAE
