Titanium Alloy Jet Turbine K7801
As featured at Aerospace Expo '98 (Long Beach Convention Centre, Long Beach,
Titanium was initially stimulated for aerospace applications in 1887 and
since then has advanced in leaps and bounds. Introducing the future of
aerospace design; the Mitsubushi Forged
Titanium Alloy Jet Turbine K7801.
Constructed almost entirely of an extremely strong titanium alloy the new
turbine surpasses any existing turbine in performance, maintenance and
resilience. (according to lab benchmarks)
New titanium forging technology has allowed increasingly complex parts
previously thought impossible to be produced with tolerances exceeding
why Titanium when Steel and Aluminum are so readily available??
Titanium has many desirable characteristics, notably low densities, which
fall between those of aluminum and iron giving titanium very attractive
strength-to-weight ratios. In addition titanium and titanium alloys
readily form stable protective surface layers which give the excellent
corrosion resistance, including oxidizing acids and chlorides, and good
elevated temperature properties up to about 440 degrees (1022 degrees F).
Table 1 compares the physical properties of Steel, Stainless, Aluminum.
Desirable Characteristics of Titanium
Superior erosion resistance.
High heat transfer efficiency.
and Methods of Production
Titanium, is the fourth most abundant metallic element in the earth's crust
and occurs naturally as an oxide ore. It is found in North America, South
America, Europe, Africa, China, Australia, Russia, as well as other countries.
Most commonly found as rutile (titanium dioxide)
and ilmenite (iron-titanium oxide)
with rutile being the most abundant course of titanium.
The commercial extraction process involves treatment of the ore with chlorine
gas to produce titanium tetra-chloride, which is purified and reduced to
sponge by reaction with magnesium or sodium. The sponge, blended with alloying
elements (and re-claimed scrap) as desired, is then vacuum melted.
meltings may be necessary to achieve a titanium homogeneous ingot which
is ready for processing into useful shapes, typically by forging followed
Manufacturing and Production
to it's unique properties Titanium
presents a unique set of machining problems, many of those problems can
be alleviated or eliminated by adhering to the following set of guidelines:
Due to these strict guidelines, manufacturing of Titanium can be
very costly. At Titanium Industries we have the unique ability to
custom make forged products for our customers complying to our strict code
of quality. For many applications the cost of titanium alloys can
be justified on the basis of desirable properties.

adequate general or local exhaust ventilation to keep fume or dust levels
as low as possible.
None required where adequate ventilation
conditions exist. If airborne concentration is high, us appropriate respirator
or dust mask.
FIRE & EXPLOSION HAZARDS: Dust may form
explosive mixture with air
GASES PRODUCED: Oxides
OF OVEREXPOSURE: Dust inhalation may cause
tightness and pain in chest, coughing, and difficulty in breathing.
Contact with skin or eyes may cause irritation.
OF ENTRY: Inhalation, skin contact and eye
& FIRST AID PROCEDURES: Call a physician.
If swallowed, if conscious, immediately induce vomiting. If inhaled,
remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. In case of contact, immediately flush
eyes with plenty of water for at least 15 minutes. Flush skin with water.
TO AVOID: Heat, flame and other sources of
Mineral acids, strong oxidizing agents, halogens and carbon dioxide.
