Turnaround times depend on the number and type of tests required, but MIL is structured to support both rapid prototype needs and full production investigations.
Typical timelines:

• Basic mechanical or hardness tests: Fast-turn
  
• Microstructural analysis & photomicrographs: 1–3 days depending on prep
  
• Failure analysis: Spec-driven and can range from several days to multiple weeks based on scope
  
• First-article metallurgical reports: Typically aligned with customer deadlines and coordinated during quoting
  

When timelines are critical—such as grounded production, urgent flight hardware, or medical device validation—MIL can often expedite work depending on lab capacity.

Yes. MIL’s metallurgical testing processes are aligned with Nadcap requirements and are widely accepted by major aerospace primes, including Boeing, Lockheed Martin, Northrop Grumman, Collins, Raytheon, and others.
Our reports follow the documentation format, traceability, and procedural rigor these primes expect, ensuring smooth acceptance and audit compliance.

Yes. Witness testing can be arranged for customers, primes, or third-party auditors when required by specification or customer contract.
MIL supports:

• On-site witness testing
• Virtual witness sessions (when allowable)
• Scheduled audits during specific stages of test execution
  We coordinate timing, safety requirements, and viewing access to ensure compliance with lab protocols.

MIL can work with either:

• Finished production parts
• Representative coupons or witness samples
• Prepared test bars or customer-supplied specimens
  
  

For destructive testing (tensile, impact, bend, microstructure), witness coupons are ideal.
If a specification requires testing on the actual part—or if the failure analysis demands it—MIL can section components with customer approval.
For non-destructive evaluation, original parts can typically be tested without alteration.

MIL performs hydrogen absorption and several related metallurgical evaluations in-house and can support hydrogen embrittlement verification through complementary testing.
For sustained-load cracking or specialized long-duration tests, we can either perform them internally when applicable or coordinate approved outside testing while maintaining full oversight and documentation.

Yes. MIL provides complete, audit-ready metallurgical reports that include:

• Raw test data
• Photomicrographs and macro images
• Microhardness profiles
• Stress/strain curves (for mechanical tests)
• Observations and conclusions
• Specification callouts and compliance statements
• Full traceability to sample, lot, and process details
  
  

Reports are formatted for easy submission to primes and quality organizations.

Yes. MIL’s testing processes and documentation are structured to support DER requirements, delegated inspection programs, and customer approval workflows.
We regularly provide metallurgical evidence, micrographs, mechanical data, and certification packages used in aviation, space, and defense regulatory submissions.
