The materials plastically deformed by the application of cold work undergoes a change in its shape and geometry in removing the charge that has been applied. This phenomenon is known as springback or elastic recovery.
To Study The Formation Of ￡ And A' Martensite In High Manganese Steels Via Deformation And Transformation Mode And Its Correlation With Mechanical Properties
Authors: Dinesh Kumar
Introduction of phases as z and a' martensite in high manganese steel should significantly posses different mechanical properties in steel. In present work five different compositions of high Manganese steels are selected with various carbon (range from 0.1-0.5) content after homozenisation and forging at 1150°C for 4 hours.

Authors: Chao ZhangH, Jianliang Zhang , Zhengjian Liu, Hui Sun, Feng Liu, Chaoquan Yao, Fei Wang
The injection of pulverized coal together with C02-stripped blast furnace gas (BFG) into the raceway of oxygen blast furnace is capable of significantly reducing energy consumption and CO2 emission.
Experimental Study On Indirect Measuring Technology Of Eaf Steelmaking Decarburization Rate By Off-Gas Analysis Technique
Authors: Kai Dong, Rong Zhu
In this paper, indirect measurement of EAF Steelmaking decarburization rate is studied. Firstly, the EAF off-gas generation process is analyzed, and the off-gas flow rate is calculated on the data of off-gas analysis and the oxygen injection, and the EAF decarburization rate is obtained indirectly.

A numerical model of 3D two-phase flow between oxygen lance jet and converter melting pool was built to simulate the effect of the new and old oxygen lances in one steel plant of China. It was found that the effect of new oxygen was better than that of old oxygen lance by contrastively analyzing thejet properties, impact effect and flow flied of liquid steel.
