一、问题的提出钛合金具有强度高,比重小,耐热性好,耐蚀性好等许多优异性能。在航空工业部门正在推广使用。但由于它的比强度高,冷塑性差,成形回弹大,在常温下难以成形,这就使它的成形成为重要技术关键。我厂新机上有钛合金零件80多项(主要用于发动机延伸筒、起动机排气管和防火隔板等部分。所有零件均用TC1板材,料厚0.6～2.0毫米)。主要零件的形状见表5。在试制过程中,为了解决成形困
First, the problem raised Titanium alloy with high strength, small proportion, good heat resistance, corrosion resistance and many other excellent performance. In the aviation industry is promoting the use of. However, because of its high specific strength, poor cold plasticity, large forming rebound, it is difficult to form at room temperature, which makes its forming an important technical key. Our new machine has more than 80 new titanium parts (mainly used for engine extension tube, starter exhaust pipe and fireproof partition board, etc. All parts are made of TC1 sheet with thickness of 0.6-2.0mm). The main parts of the shape shown in Table 5. In the trial process, in order to solve the forming trap
