]. The inner diameter and height of the heat treated hot work tool steel (H13) die used were about 100 and 90 mm, respectively, and the inner surfaces of the die were coated with a water-based graphite coating prior to each test. First, based on the previous experiences of the authors [21,28-33] and some preliminary trials, Al-4.5wt.%Cu cylindrical inserts (diameter of 100 mm and height of (25±1) mm......

[10]. Alloys containing Al-Ni based IMCs are mainly used for high temperature structural products, friction resistant coating materials and corrosion resistant coatings to protect from aggressive...-EDS (punctual and mapping) at the P5 and P50 positions are presented in Figs. 12 and 13, respectively. The results suggest the formation of Al7Cu4Ni and other Ni-rich based IMCs. CHEN and THOMSON [43......

%Si-20%Cu钎料合金虽然钎焊温度较低,然而合金中存在大量的Al2Cu金属间化合物和Al-Si-Cu共晶组织,导致钎料合金脆性很大,极难加工成薄片;同时,钎焊接头组织中也含有大量的Al2Cu金属间化合物,导致钎焊接头具有较低的抗剪强度. 为了降低Cu含量过高带来的不利影响,研究学者利用Cu降低熔点的同时加入少量Ni,以使钎料保持良好的力学性能和抗腐蚀性能.于文花等[41]采用Al-Si-Cu-Ni钎料钎焊6063铝合金时发现,Cu,Ni,Si对钎焊接头剪切强度的影响由大到小依次为Cu,Si,Ni;随着钎料中Cu,Ni,Si 含量的增加,钎焊接头的剪切强度先增加后减小,分别为10%,2.6%,7.5%附近剪切强度达到最高;当Cu含量超过20%时,钎料合金中会形成连续的Al-Cu金属间化合物,恶化了钎焊接头的力学性能.HUMPSTON等[42]研制的Al-5Si-20Cu-2Ni钎料熔化温度......
