of more than 200℃. The semi-solid microstructures were considerably refined and globular regardless of the alloy composition, being suitable for semi-solid processing. Furthermore, each fcc phase... to coarsen. In conclusion,this work showed that these alloys can be potential candidates for semi-solid processing.关键词:......
Effect of Semi-Solid Isothermal Heat Treatment on Microstructure of ZL104 Aluminum Alloy () 摘要:The feasibility of fabricating ZL104 aluminum alloy with non-dendritic microstructure by semi-solid isothermal heat treatment process and the effects of holding temperature and time on the semi-solid isothermal heat-treated microstructure of the alloy, are investigated. The research results indicate......
October 2015 Abstract: In order to study the hot fractures in relation to the semi-solid processing, the tensile tests of an extruded 7075 aluminum alloy which is based on Al-Zn-Mg-Cu system were carried... equations which are critical for tensile behavior are proposed. Key words: Al-Zn-Mg-Cu alloy; mechanical behavior; semi-solid processing; fracture 1 Introduction The Al-Zn-Mg-Cu alloys have great age......
excellent properties. Thixoforging is one type of semi-solid metal processing [1-7]. It is no longer a novel, but rather a powerful technology for forming alloys in the semi-solid state to near net...]. Journal of Materials Processing Technology, 2002, 130-131: 587-593.

behavior of the semi-solid A356 aluminum alloy was investigated by simulation methods. The simulation results show that these processing parameters have an important effect on the filling behavior...Numerical simulation on the rheo-diecasting of the semi-solid A356 aluminum alloyYue-long Bai1), Jun Xu1), Zhi-feng Zhang1), Wei-min Mao2), and Hong Xu3) 1) General Research Institute for Non-ferrous......
from wrought alloys is a challenge due to hot tearing[1-3]. Although an opportunity arose with the advent of semi-solid processing, it still remains largely out of reach on a meaningful commercial scale.... The semi-solid temperature of the material in the cup was measured by a thermocouple. Processing stopped after the thermocouple signal reached the preset SSM temperature. At this point, the cup was ejected......
technology, the semi-solid processing(SSP) of metals has received considerable attention and more researches and explorations have been carried out since 1970s, when SPENCER and FLEMINGS[1] conducted... electromagnetic stirring, an advanced semi- solid metal processing technology, namely, the annulus electromagnetic stirring(AEMS) process[12], has been developed and the effects of the process parameters......
