我部于1983年12月7日至11日在无锡召开了应力,腐蚀 K_(Iscc)标准试验方法审定会。来自部内、外31个单位的39名代表一致同意下述三个试验方法作为我部标准试验方法报部审批。1.高强合金悬臂弯曲预裂纹试样 K_(Iscc)试验方法;2.楔形加载的 WOL 预裂纹试样 K_(Iscc)、da/dt 试验方法;3.金属材料双悬臂试样平面应变应力腐蚀 K_(Iscc)、da/dt 试验方法。上述试验方法是我部厂、所、院校11个单位组成的课题组经过四年的工作提出的,它将是我国预裂纹试样
Our department held the validation meeting of the K_ (Iscc) Standard Test Method for Stress and Corrosion in Wuxi from December 7 to December 11, 39 delegates from 31 units inside and outside the unit agreed that the following three test methods should be approved by the Ministry of Standard and Test Method. 1. K_ (Iscc) test method for pre-cracked cantilever specimens of high-strength alloy; 2. K_ (Iscc) and da / dt test methods for WOL pre-cracked specimens with wedge loading; 3. Plane strain stress corrosion testing of double- K_ (Iscc), da / dt test method. The above test method is proposed by our group of factories, institutes and institutes with 11 units after four years of work. It will be a sample of China’s pre-cracked specimen
