Standard Test Method for Stress-Corrosion of Titanium Alloys by Aircraft Engine Cleaning Materials
|Standards number:||ASTM F0945-12R19|
|Keywords:||controlled temperature conditions; engine cleaners; maximum operating concentration; metallographic inspection; prestressed titanium alloys; stress-corrosion cracking (SCC);|
1.1 This test method 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.
1.2 The evaluation is conducted on representative titanium alloys by determining the effect of contact with cleaning and maintenance materials on tendency of prestressed titanium alloys to crack when subsequently heated to elevated temperatures.
1.3 Test conditions are based upon manufacturer's maximum recommended operating solution concentration.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
