Stress Corrosion of Titanium Alloys, Effect of Cleaning Agents on Aircraft Engine Materials

CURRENT
ARP1795A
This document establishes a test procedure for determining the propensity of aircraft turbine engine cleaning and maintenance materials for causing stress-corrosion cracking of titanium alloy parts. The evaluation is conducted on representative titanium alloys by determining the effect of contact with cleaning and maintenance materials on tendency of pre-stressed titanium alloys to crack when subsequently heated to elevated temperatures.

AMS1371A
This specification covers a rust removing compound in the form of a solid, generally powdered, to be dissolved in water, and heated. This compound has been used typically for the removal of oxides from ferrous components during manufacture or at overhaul, but usage is not limited to such applications. This compound product may be acidic, but is usually highly alkaline and is not suitable for processing aluminum components. Avoid mixed metals during processing.
