MODIFYING THE MICROSTRUCTURE AND PROPERTY OF 30CrMnSi STEEL BY SUBCRITICAL AUSTENITE REVERSE TRANSFORMATION QUENCHING
Article history: Received: 23.12.2013. Received in revised form: 15.01.2014. Accepted: 15.01.2014. Subcritical austenite reverse transformation quenching was used to improve the mechanical properties of 30CrMnSi steel, and the microstructure and mechanical properties of the samples were analyzed by subcritical austenite reverse transformation quenching. Experimental results show that subcritica...

Certain amount of retained austenite can increase ductility of steels because of the TRIP phenomenon during plastic deformation. One method for achieving this is partitioning of carbon into austenite to stabilize it at room temperature. The quenching and partitioning (Q&P) heat treatment leads to a microstructure consisting of martensite and stabilized retained austenite between martensite plat...
متن کاملmicrostructure and mechanical properties of a low alloy high carbon steel processed by quenching and partitioning process
the quenching and partitioning (q&p;) process is a new heat treatment cycle to produce the third generation of advanced high strength steels based on diffusion of carbon from martensite to retained austenite phase. the application of this process for various steels leads to a remarkable combination of mechanical properties including high strength and good ductility. using this process in automo...
متن کاملRoom temperature texturing of austenite/ferrite steel by electropulsing
The work reports an experimental observation on crystal rotation in a duplex (austenite + ferrite) steel induced by the electropulsing treatment at ambient temperature, while the temperature rising due to ohmic heating in the treatment was negligible. The results demonstrate that electric current pulses are able to dissolve the initial material's texture that has been formed in prior thermomech...
متن کاملThermal Stability of Retained Austenite in Bainitic Steel: an in situ study
The tempering of two–phase mixtures of bainitic ferrite and carbon–enriched retained austenite has been investigated in an effort to separate the reactions that occur at elevated temperatures from any transformation during cooling to ambient conditions. It is demonstrated using synchrotron X–radiation measurements, that the residue of austenite left at the tempering temperature partly decompose...
