试验在高速锻锤上进行。目的是为了在高速条件下检验在技术上和经济上应用的可能性。在此试验中使用了各种不同的铝合金。材料试验表明,毛料予先得到正确处理,可以避免机械时效,从而可以避免产生机械时效后其它的事后处理。Al-Mg-Si0.5合金各种热处理制度的机械性能列于表1。对于Al-Mg-Si0.5和Al-Mg-Si1合金毛料在变形前进行固溶退火,变形后可以得到高的强度值。表2列出了不同予先处理制度的影响。 The test was carried out on a forging hammer at high speed. The purpose is to test the possibility of application technically and economically under high speed conditions. A variety of different aluminum alloys were used in this test. Material tests show that the wool is properly treated first to avoid mechanical aging, thereby avoiding the need for additional post-mechanical aftertreatment. The mechanical properties of various heat treatment regimes for Al-Mg-Si0.5 alloys are listed in Table 1. For Al-Mg-Si0.5 and Al-Mg-Si1 alloy wool before solution deformation annealing, deformation can be obtained after the high intensity value. Table 2 shows the impact of different pre-treatment systems.
