Preparation of AZ91D magnesium alloy semi-solid billet by new strain induced melt activated method JIANG Ju-fu(姜巨福)1, 2, LUO Shou-jing(罗守靖)1, ZOU Jing-xiang(邹经湘)2 1. School of Materials Science...; accepted 6 April 2006 Abstract:New strain induced melt activated (new SIMA) method for preparing AZ91D magnesium alloy semi-solid billet is introduced by applying equal channel angular extrusion......
the application of high Cu content Ti-Ni-Cu SMAs. In recent years, melt spinning technique has been utilized to fabricate high Cu-content Ti-Ni-Cu alloys in order to avoid the intrinsic restriction. Ti-Ni-Cu alloy ribbon can exhibit amorphous or crystalline structure dependent on melt-spinning parameters[7]. Nevertheless, as-spun amorphous Ti-Ni-Cu ribbon fabricated by using a high cooling rate shows......
