Analysis and Calculation of Carbon Content in Austenitizing of Cast Iron
Advanced Materials Research, 2013Co-Authors: Wen Bang Gong, Yun Zhang, Gang Yu XiangAbstract:In this paper, a formula for the calculation of carbon content during austenitizing of cast iron was deduced, considering the effect of silicon content on the Heat Treatment Parameter. According to this formula, the carbon content of the austenite in a certain austenization temperature for a cast iron with given components can be easily calculated, and the austenization temperature for getting the expected carbon content in the austenite can also be determined. Besides, according to the relationship between austenization temperature Tx and the according carbon content Cax, and considering the effect of silicon content, the diagram of Cax, Tx and silicon content during the austenitizing process of cast iron was made.

formula derivation and application for carbon content versus Heating temperature in austenitizing of cast iron
Defect and Diffusion Forum, 2009Co-Authors: Wen Bang Gong, Gang Yu XiangAbstract:In this paper, a formula for the calculation of the carbon content during the austenitizing of cast iron was deduced, considering the effect of silicon content upon the Heat-Treatment Parameter. According to this formula, the carbon content of the austenite at a certain austenization temperature for a cast iron with given components can be easily calculated, and the austenization temperature required to give the expected carbon content in the austenite can also be determined. Moreover, according to the relationship between the austenization temperature Tx and the associated carbon content Cax,, and considering the effect of the silicon content, a diagram showing Cax, Tx and the silicon content during the austenitizing of cast iron was prepared.

Effect of T4 and T6 Heat Treatment Parameter on microstructure and hardness of AZ91+x%La magnesium alloy
Transactions of Materials and Heat Treatment, 2011Co-Authors: Xu Bing-sheAbstract:On the different Heat Treatment Parameter of T4 and T6,the microstructure and hardness of AZ91 + x% La magnesium alloy have been investigated.The results indicate that,after T4(410+16 h) Heat Treatment,hardness are decreased,because of most of the β-phase are dissolved into the matrix.After T6(170 ℃+24 h) Heat Treatment,because lamellar phase β-Mg17Al12 is precipitated on the grain boundary or in the crystal grain,hardness are increased significantly,especially AZ91+0.16% La magnesium alloy,reaching to 138 HV.

Banded structure in Dual Phase steels in relation with the austenite-to-ferrite transformation mechanisms
Journal of Materials Science, 2011Co-Authors: Benoit Krebs, Lionel Germain, Alain Hazotte, Mohamed GounéAbstract:New experimental data are reported relative to the development of banded structures in Mn-segregated Dual Phase steels during the austenite-to-ferrite transformation stage of their final Heat Treatment. Two types of ferrite are detected to grow simultaneously, i.e. allotriomorph and acicular ferrite, with distinct consequences on the topology of the final (ferrite + martensite) microstructure: allotriomorph ferrite sharpens the banded structure of ferrite and martensite between Mn-poor and Mn-enriched regions, respectively, whereas acicular ferrite favours more isotropic microstructures. Owing to an original image Treatment procedure, the sharpness of banded structure is quantitatively analyzed for different Heat Treatment conditions. Results confirm those of previous works, but we propose to rather explain them by considering that a change in a Heat Treatment Parameter results in a variation in the respective amounts of both ferrite types.
