TC11 titanium alloy probes are critical for military
aircraft engine testing, where high G-loads (up to 10G)
demand exceptional tensile strength (σb >1100MPa) to
maintain structural integrity during dynamic maneuvers.

TC11’s strength stems from its alpha-beta titanium
alloy composition, which combines high tensile strength
with good ductility. A tensile test showed TC11 specimens
had a σb of 1150MPa at room temperature, exceeding the
1100MPa threshold required for high G-load applications.
This strength ensures the probe remains intact during
rapid acceleration, unlike 304 stainless steel (σb
500MPa), which would deform under similar loads.
Heat treatment further enhances strength. A solution
treatment at 950°C followed by aging at 500°C increases
σb by 10% and improves fatigue resistance, critical for
withstanding cyclic G-loads during repeated engine tests.
A military lab found treated TC11 probes survived 10,000+
load cycles, compared to 5,000 cycles for untreated
material.
Probe design must distribute stress evenly. A
streamlined stem with a 1:10 taper reduces stress
concentration at the head-stem junction, a common failure
point in high G-load scenarios. In a simulated dogfight
test, tapered probes showed no signs of cracking, while
straight-stemmed probes developed fatigue cracks after
200 maneuvers.
Quality control includes 100% ultrasonic inspection
to detect internal defects, as even small inclusions can
reduce strength by 20%. This rigorous testing ensures
TC11 probes meet the demanding requirements of military
aircraft engine environments.
