LY12、LC4、LC9三种管材是用于飞机滑撬前后横梁的重要承力结构,我们利用单轴拉伸试验得到的P-△l曲线,对工程σ-ε曲线及有关性能进行了试验研究,提供了数据,并建立了相应的试验方法及数据处理程序。一材料及试样材料:LY12、LC9、LC4热挤压圆管尺寸:φ100×10 状态:LY12 CZ淬火+自然时效 LC9 CS淬火+人工时效 LC4 CS淬火+人工时效三种材料的动态性能数据见表1。试样及取样部位如图1、2所示。试样按HB5143-80中要求加工。
LY12, LC4, LC9 three kinds of pipe is used for the skid before and after the aircraft an important load-bearing structure, we use the uniaxial tensile test P-Δl curve, the engineering σ-ε curve and related properties were studied , Provided the data, and established the corresponding test methods and data processing procedures. A material and sample materials: LY12, LC9, LC4 hot extrusion tube size: φ100 × 10 state: LY12 CZ quenching + natural aging LC9 CS quenching + artificial aging LC4 CS quenching + artificial aging dynamic properties of three materials, see Table 1. Samples and sampling sites shown in Figure 1,2. Sample processing requirements by HB5143-80.
