Layered composite elastic plastic damping steel sheet and manufacturing method and application thereof
The invention relates to an elastic plastic damping steel sheet having good corrosion resistance, low strength and good low cycle fatigue performance, and a manufacturing method and application of thelayered composite elastic plastic damping steel sheet. The elastic plastic damping steel sheet has (2n +1) layers of composite structures, wherein n is a positive integer. The elastic plastic dampingsteel sheet is formed by alternatively arranging austenite structure layers and ferritic structure layers, and completely metallurgical bonding is realized at joint interfaces of every two adjacent layers. The upper surface layer and the lower surface layer of the elastic plastic damping steel sheet must be austenite structure layers. The layered composite damping steel sheet with enhanced low cycle fatigue performance is prepared by assembly, hot rolling, and post-rolling annealing production processes or assembly, hot rolling, pickling, cold rolling, and post-cold-rolling annealing production processes. The yield strength of the layered composite damping steel sheet with enhanced low cycle fatigue performance is less than 300 MPa; under the circulating stretching - compressing loading condition, when the strain amplitude, the strain ratio and the loading frequency are 1%, -1.0 and 0.1-0.2Hz, the stress magnitude is smaller than 400 MPa, and the room temperature fatigue life of the steel sheet is larger than 1500 weeks.
本发明涉及一种具有良好耐蚀性能、低强度和良好低周疲劳性能的弹塑性阻尼钢板及其制造方法与应用。其具有(2n+1)层复合结构，其中n为正整数，由奥氏体组织层和铁素体组织层交替排列组成，并且相邻两层的接合界面处实现完全冶金接合；所述弹塑性阻尼钢板的上表层、下表层必须为奥氏体组织层。具有增强低周疲劳性能的层状复合阻尼钢板经组坯、热轧、热轧后退火生产工艺流程或组坯、热轧、酸洗、冷轧、冷轧后退火生产工艺流程制备得到。具有增强低周疲劳性能的层状复合阻尼钢板的屈服强度＜300MPa；在循环拉伸‑压缩加载条件下，当应变振幅、应变比和加载频率分别为1％、‑1.0和0.1～0.2Hz时，应力幅值＜400MPa，并且钢板的室温疲劳寿命＞1500周次。
