Overview

EN 3314:2019 is a CEN aerospace series standard that specifies requirements for titanium alloy TI‑P64001 supplied as bars for machining with diameter D ≤ 75 mm. The standard defines chemical limits, heat treatment (solution treated and aged), mechanical property minima by diameter range, microstructure acceptance and delivery/inspection requirements intended for aerospace applications.

Key technical points from the standard include:

• Product form: Bar for machining, diameter D ≤ 75 mm.
• Delivery condition: Solution treated and aged; delivery condition code U is specified.
• Heat treatment ranges: Solution treatment typically in the range 860 °C ≤ θ ≤ 960 °C with quench in agitated water; aging in the range 460 °C ≤ θ ≤ 600 °C for 2 h ≤ t ≤ 8 h (air cooling after aging). (EN 3314:2019)
• Composition highlights: Aluminium and vanadium are the principal alloying elements (Al ≈ 5.5–6.75 %, V ≈ 3.5–4.5 %). Limits for interstitials and minor elements (oxygen, nitrogen, hydrogen, iron, carbon) are given to control performance and machinability.

Key Topics

• Mechanical properties by diameter range: The standard gives minimum proof stress (Rp0.2), tensile strength (Rm), elongation and reduction of area values for diameter bands (D ≤ 25; 25 < D ≤ 38; 38 < D ≤ 50; 50 < D ≤ 75). Typical minima include high proof and tensile strengths appropriate for structural aerospace use, and minimum elongation ≥ 8 % with reduction of area ≥ 20 %.

• Microstructure and defect acceptance: Microstructure acceptance follows EN 3114‑002 with specific acceptable and non‑acceptable microstructure classes for the different diameter ranges. Internal and external defect criteria reference EN 4800‑002.

• Traceability and inspection: The standard mandates marking, dimensional inspection and designation rules (see EN 2600) to ensure traceability and conformity for aerospace procurement.

Applications

EN 3314:2019 is intended for manufacturers, purchasers and engineers specifying titanium bars for aerospace components where high strength, controlled microstructure and reliable machining characteristics are required. Typical uses include:

• Precision machined structural parts and fittings
• High‑strength, lightweight components in airframe and engine applications
• Situations requiring strict material traceability and documented heat treatment

Benefits include predictable mechanical performance after machining, consistent microstructure for fatigue and fracture performance, and compliance with aerospace procurement practices.

Related Standards

Key normative references and related standards cited by EN 3314:2019 include:

• EN 2500‑004 - instructions for drafting metallic material standards (titanium)
• EN 2600 - designation of metallic semi‑finished products
• EN 3114‑002 - microstructure test method for (α + β) titanium alloy bars
• EN 4258, EN 4267, EN 4500‑004, EN 4800‑002 - organization, dimensions and specific rules for titanium materials

For purchasers and suppliers, aligning specifications with these referenced standards ensures consistent acceptance criteria, sampling and testing for TI‑P64001 bars used in aerospace manufacturing.
