Trans. Nonferrous Met. Soc. China 22(2012) 1182-1189 Simulation of temperature field and metal flow during continuous semisolid extending extrusion process of 6201 alloy tube GUAN Ren-guo, ZHAO Zhan... semisolid extending extrusion (CSEP) method was proposed. Temperature field and metal flow during continuous semisolid extending extrusion process of 6201 alloy tube were studied. During the process......
Hydrogen Fixation Effect of Rare Earths in Pure Aluminium and Aluminium Alloys李道韫,徐连棠,张会义摘 要:<正> The areal distribution of some elements in the rare earth bearing spheroidal phases in pure aluminium andAl-Mn alloys was studied by SIMS(secondary ion mass spectrometry).The results show that cerium,iron.silicon and hydrogen are significantly......
Formability evaluation of AZ31B extruded tube for hydroforming processHE Zhubin,LIU Gang,YUAN Shijian,and LIANG Yingchun School of Materials Science & Engineering,Harbin Institute of Technology,Harbin 150001,China摘 要:Hydroforming of magnesium and aluminum alloy tube at elevated temperature is becoming a very promising method to manufacture light......
(Fe,Mn)3Si2, which provided the lower balanced Fe concentration in the melt in comparison with other Fe-rich intermetallics. Key words: aluminium alloy; solidification; intermetallics; iron removal 1 Introduction Aluminium alloys have been extensively used in foundry practice for manufacturing structural components. They are always regarded as being completely recyclable, which represents one......
Formability determination of AZ31B tube for IHPF process at elevated temperature LIN Yan-li1, HE Zhu-bin1, YUAN Shi-jian1, WU Jia2 1. School of Materials Science and Engineering, Harbin... Abstract: Ring hoop tension test and tube bulging test were carried out at elevated temperatures up to 480 °C to evaluate the formability of AZ31B extruded tube for internal high pressure forming (IHPF......
J. Cent. South Univ. (2020) 27: 3721-3732 DOI: https://doi.org/10.1007/s11771-020-4572-y Mechanism of necking defect of 6082 aluminium alloy rolled by cross-wedge rolling method based on material... in aluminium alloy shaft parts. To accurately predict necking defects, new judgement conditions are established based on the thermal performance of 6082 aluminium alloy. The limit-sectional shrinkage without......
