Materials Science and Technology, 2007
A combination of neural networks and genetic algorithms has been used to design a TRIP assisted steel in which the silicon concentration is kept low. In this context, the steel has a novel microstructure consisting of δ ferrite dendrites and a residual phase which at high temperatures is austenite.

Finite Element Modelling of TRIP Steels
steel research international, 2004A constitutive model that describes the mechanical behaviour of steels exhibiting “Transformation Induced Plasticity” (TRIP) during martensitic transformation is presented. Multiphase TRIP steels are considered as composite materials with a ferritic matrix containing bainite and retained austenite, which gradually transforms into martensite.

Microstructural characterization of TRIP-aided steels
Materials Science and Engineering: A, 2008Abstract Cold rolled steel sheets containing 0.4C, 0.5Si, 1.5Mn, 1.0Al, 0.02Nb and 0.1Mo (mass%) were subjected to three heat treatment schedules to produce TRIP-aided steels with annealed martensite (AM), bainitic ferrite (BF) and polygonal ferrite (PF) matrix microstructures.

Twinning and Tripping in 10% Mn steels
Materials Science and Engineering: A, 2014Abstract In the present work, a medium Mn, Fe–Mn–C–Al–Si alloy was subjected to different heat treatment conditions and subsequent deformation to understand the effect of these processes on austenite. It was found that, after intercritical annealing, the microstructure was ferrite plus austenite duplex phase (FADP) regardless of cooling rate to room ...

TRIP steel with reduced silicon content
Steel Research, 1999At present high strength thin sheet steel grades are gaining considerable market shares due to the intensified application in the automotive industry. Although several new high strength steels for cold forming have been developed and continuously improved for some decades there is still a necessity to increase the formability at a given high strength ...

Powder Metallurgy and Metal Ceramics, 2004
The structure and properties of low-alloy austenitic steels prepared by hot compaction are studied. It is shown that concentration inhomogeneity is not always a reason for reduced mechanical properties. A high level of structural strength and dimensional accuracy may be achieved for powder steels with a structure of metastable austenite. An improvement
