Hc380/590tr Phase Change Induced Plastic Steel information
TRIP steel is a super high strength steel with increased plasticity
caused by the progressive martensitic transformation process in the
steel structure. In 1967, V.F. Ackay et al. designed a low carbon
and high alloy metastable austenitic steel containing a large
amount of chromium, nickel, molybdenum, manganese and silicon. The
martensitic point Ms(upper limit of temperature at which
deformation causes martensitic transformation) of this steel is
lower than room temperature. After low temperature deformation
treatment (76%~80% deformation at 450℃), the Md point becomes
higher than room temperature, but the Ms point is still much lower
than room temperature (less than 196℃). The microstructure of the
steel is characterized by fine dispersed alloy carbide and high
density dislocation in austenite.
The austenitic steel with this structure will change the austenite
into martensite at the crack front when it is subsequently used at
room temperature due to stress concentration at the crack front.
Because the formation of martensite requires a large amount of
energy, which makes the propagation of cracks difficult, it
increases both the strength of steel (martensite strengthening) and
the fracture toughness (KIC) (energy consumption for propagation of
cracks).
The Plasticity resulting from this progressive local martensitic
Transformation is known as Transformation Induced Plasticity
(TRIP). The composition and properties of the phase change induced
plastic steel are shown in the table. This steel is the ultra high
strength and tough steel with the best fracture toughness
available. The KIC can reach 17.7 mn. m at room temperature and 4.6
mn. m at 196℃.
