during semi-solid isothermal heat treatment were investigated deeply in the present work. Results showed that the lamellar (Mg,Al)3Gd phases transformed into the particle-like Al2Gd phases in AZ31 magnesium alloys with Gd addition during semi-solid isothermal heat treatment, leading to yielding more spherical α-Mg grains. When Gd content is 2.0 wt. %, the size of semi-solid spherical grains......
internal high-pressure forming and aging treatment, was developed. The AA6061 alloy tube via heat treatment satisfied the forming requirement, and the granule medium internal high pressure forming method... which can be strengthened by heat treatment. The mechanical properties can be adjusted by solution treatment and aging treatment with the content of precipitates controlled. XIANG et al [8] studied......
Effect of heat treatment on microstructure and dimensional stability of ZL114A aluminum alloy JIANG Long-tao(姜龙涛), WU Gao-hui(武高辉), YANG Wen-shu(杨文澍), ZHAO Yong-gang(赵永刚), LIU Shan-shan(刘珊珊) School of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China Received 23 October 2009; accepted 16 August 2010 Abstract: The effects of heat treatment process......
for nanocomposites. T6 heat treatment (solid solution at 530 °C for 2 h and aging at 175 °C for 6.5 h in this work) is also considered an effective method to strengthen nanocomposites [15-17]. CASATI et al [16... samples were rolled at 500 °C with a speed of 20 mm/s, from 3 mm to 1.5 mm in three passes. Lastly, a solid solution treatment at 530 °C for 2 h and aging at 175 °C for 6.5 h, named T6 heat treatment, were......
J. Cent. South Univ. (2016) 23: 515-522 DOI: 10.1007/s11771-016-3097-x Effect of optimal aging treatment on magnetic performance and mechanical properties of sintered Nd-Fe-B permanent magnets DING... could be improved through aging treatment, especially the intrinsic coercive force. But it is accompanied by a decrease of strength and fracture toughness. Theoretical calculation confirms......
Effect of aging treatment on irradiation-induced segregation of high Mn-Cr steel D. S. BAE1, S. P. LEE2, Y. R. CHO3, H. TAKAHASHI4 1. Department of Advanced Materials Engineering, Dong-Eui...: To investigate the effect of aging treatment on irradiation-induced segregation of high Mn-Cr steel, specimens for electron-beam irradiation were prepared from the high Mn-Cr austenitic steel which was solution......
behavior and then determine the technology parameter of enhanced solution heat treatment for high strength. The results show that an appropriately enhanced solution treatment can make final solution... the yield strength and the resistance to over aging can be improved considerably without a large deterioration to tensile ductility. 关键词:aluminum alloy; mechanical property; solution treatment; aging......
-independent logarithmic decrement for the specimens annealed at higher temperatures is a little lower than that for as-cast specimen, and it increases with increasing temperature of heat treatment. Microstructure changes due to heat treatment are responsible for changes of the logarithmic decrement. Key words: AZ61 magnesium alloy; heat treatment; damping; dislocation  ......
