Figure 3. Typical tensile properties of Ti-64 and ATI Titan 23TM from LPBF material. Due to the heat treatability
of ATI Titan 23TM, tensile properties can be tailored using heat treatment to suit a variety of applications.
both Electron Beam Melting and Direct
Metal Laser Sintering are geared toward
exacting and demanding performance
environments, addressing demanding
applications in aerospace, defense and
medical markets.
After internal production of ATI Titan
23™ powder and LPBF samples, it was
found that the alloy lacks martensitic
structure due to its slow precipitation
kinetics. This leads to parts with lower
residual stresses and distortions that are
three-times less compared to the same
parts printed using Ti-64 (Figure 2). The
reduced part failure due to lower part
distortion allows ATI Titan 23™ to be
used where Ti-64 is not an option. In
addition, due to the heat treatability of
beta-rich alloys, ATI Titan 23™ can be
heat treated in a variety of ways to produce
a full range of mechanical properties
to suit the application.

Depending on the heat treatment
used, ATI Titan 23™ is able to generate
tensile properties 20% higher
than Ti-64 (Figure 3). The combination
of printability and heat treatability
of beta-rich alloys, and in particular
with ATI Titan 23™, make this
alloy selection a potential solution
for challenging titanium parts made
in LPBF systems.
As the acceptance and application of
additive manufacturing technology
continues to evolve and grow, alloy selection
will prove to be an important
part of the development process. Selecting
the right material up front can
increase chances of success and open
the door to new applications and performance
enhancements. This journey
continues for beta titanium alloys with
the next phase of development with
ATI Titan 23™ underway, including
partnering with customers to solve
their challenges and further explore
the possibilities of next-generation additive
parts.
