Role of deformation-induced martensite in the transformation-induced plasticity (TRIP) metastable austenitic steels was studied by examining effects temperature on tensile properties Fe–18%Cr–6%Ni–0.2%N–0.1%C (6Ni–0.2N–0.1C) steel. The obtained tests at various temperatures between 123 and 373 K were compared with those SUS304 0.2% proof stress, strength, uniform elongation 6Ni–0.2N–0.1C steel ...

Due to the moderate formability of low alloy high strength steels, (TRIP) steels called "transformation induced plasticity" have been developed. They are especially used in production automobile shock absorbers and beam supporting parts. The microstructure these consists distribution ferrite, bainite (5 - 10%) residual austenite phases matrix. generally provided by structure. During shaping, tu...

In this work, dynamic mechanical properties of three high-manganese steels with TRIP/TWIP or fully TWIP characteristics are studied. High strain rate experiments in the range of true strain rates between ~500 and 1800 /s are conducted using a dynamic torsional testing setup. All the three steels show a positive strain rate sensitivity in the intermediate range of strain rates (up to 500 /s). Bu...

Discretization of continuous attributes is a necessary pre-requisite in deriving association rules and discovery of knowledge from databases. The derived rules are simpler and intuitively more meaningful if only a small number of attributes are used, and each attribute is discretized into a few intervals. The present research paper explores the interrelation between discretization and reduction...

In recent years, TRIP/TWIP steels have been the focus of great attention thanks due to their excellent tensile strength-ductility combination. The compression tests were performed at different temperatures from 25 to1000°C to study the mechanical behavior of advanced austenitic steel with 21% manganese plus bearing Ti. The results indicated that the plastic deformation is controlled by deformat...
