treatment QU Tian-peng(屈天鹏), WANG De-yong(王德永), WANG Hui-hua(王慧华),HOU Dong(侯栋), TIAN Jun(田俊) Shagang School of Iron and Steel, Soochow University, Suzhou 215021, China Central South University Press... oxide MgAl2O4 or MgO always existed in molten steel after magnesium treatment. In consideration of the segregation and enrichment of solute elements at the solidification front, the Ohnaka......
Carbon–Iron Microfibrous Material Produced by Thermal Treatment of Self-rolled Poly(4-vinyl pyridine) Films Loaded by Fe2O3 ParticlesCamelia Matei Ghimbeu,Aleksandr I.Egunov,Andrey S.Ryzhikov,Valeriy A.Luchnikov摘 要:Ensembles of freeze-dried self-rolled polymer micro-scrolls are explored as template media for producing carbon–iron based composites......
Analysis on Phase Transformation (ATP) Using Computational Thermal Principles (CTP) K.Palaniradja1,V.Soundararajan1,N.Alagurmurthi1 (1.Department of Mechanical Engineering, Pondicherry Engineering College, India) 摘要:Computer analysis based on computational thermal principles to predict the transformation kinetics in steels at varying temperatures is of great practical importance in different......
originate from the stress waves and they may have higher hardness. PROSKUROVSKY et al[2] believed that the thermal stress wave induced by HCPEB treatment was the dominant factor for the structure and property varieties beyond the HAZ. They described the thermal stress wave in Fe induced by the HCPEB treatment using numerical simulations. The amplitude of the simulated thermal stress wave is as weak......
states of thermal fatigue specimens are selected:the as-cast,solutionized as well as aged states.The solution treatment is carried out at 1260°C for 24 h,which results in the dissolution of most... M23C6carbides in the matrix.The results indicate that the heat treatment can improve the thermal fatigue properties of the alloy and the effect of the solution treatment is more prominent than......

It was found that after the solution heat treatment, the texture type clearly......
350℃ - Thermal Stability of Austempered Ductile Iron M.Pellizzari1,A.Molinari1,M.Zadra1 (1.Department of Materials Engineering and Industrial Technologies, University of Trento Italy) 摘要:The thermal stability of an ADI has been studied by isothermal aging at 350℃ for 150 hours, measuring the amount of retained austenite and its carbon content by X-ray diffractometry. The influence of different......
