Fatigue Behaviour of Metal Matrix Composites王中光,孙正明,于维成摘 要:<正> Based mainly on the work done at the authors’laboratory in recent years,this paper examines whatis currently known about the cyclic deformationand fatigue properties of metal matrix composites,with particular emphasis on discontinuous fiber(whisker or particulate)-reinforced Al......
of Si and AlN phases during the infiltration process. Key words: AlN; ceramic-matrix composites; thermal properties; liquid metal infiltration 1 Introduction AlN possesses high thermal conductivity (TC... of a ductile phase such as Al into brittle ceramic. Al and its alloys are very attractive candidates as matrices for the production of ceramic reinforced metal composites due to their high TC of 180-230 W/(m......
Life cycle inventory for base metal ingots production in Japan including mining and mineral processing processes by cost estimating system database

1. Department of Materials... activities to the inventory of upper stream products.
Key words: LCI; LCA; base metal ingots; cost estimating system; mining process
and the formation of "vortex" multilayer structure. The mechanisms for the formation of such structures were discussed. Key words: high-pressure torsion; severe plastic deformation; metal matrix composite; vortex... the action of pressure produced by outer layers of the sample. As a result, despite high degrees of strain, the sample is not broken. In some HPT installations, to decrease the outflow of a metal, the bottom......青铜/铌复合材料的高压扭转变形过程
