Taken as a whole,
the people and equipment capabilities of Pittsburgh Materials Technology
Inc.
(PMTI) are unique. This page details the equipment used for material processing
and characterization and has links to pages with more specific information.

insight on how PMTI may be able to provide solutions to your materials
challenges.
Vacuum Arc
Melting
- Consumable electrode:
ingots to 5" diameter - PMTI's use of AC in the VAR permits the melting
of alloys unable to be melted with DC and promotes alloy homogeneity.
PMTI is working toward
making a 6" diameter mold capability operational.
- Nonconsumable electrode:
button and trough melting.
Primary
Metalworking
- High energy rate
extrusion and forging to 2200° C - The DYNAPAK system is an essential
tool in refractory alloy development and manufacture as well as consolidation
of cryo milled alloy systems.
- We recently used
a high-speed camera to capture the action of an upset forging at 2,000
frames per second. The billet was cryo-milled Aluminum powder. The upset
forging accomplishes both consolidation and disc production. Click here
to see a video.
Secondary
Metalworking
- Swaging to 1600°
C; 1" diameter limit
- Cold and hot rolling
to 1600° C; 7" width limit
- Metal foil rolling
with 7" width limit
Heat
Treating
