两种工程材料深冷处理研究
|
摘要
深冷处理技术的应用范围很广,它不仅可以用于黑色金属材料及其合金、有色金属材料及其合金还可用于碳化物、塑料、硅酸盐等非金属材料,主要应用于改善和提高材料的力学性能,延长零件和工具的使用寿命,提高耐磨性,增加材料的稳定性等。在社会的很多领域,如能源新工艺、工业生产、航空航天、军事、医疗卫生中深冷处理都有它非常重要的用途和价值。
本文对Y系列和江铃系列铝合金内燃机轴瓦和CSP连铸连轧SPCC与SPHC两种钢板进行采用多时段的深冷处理,并观察了显微组织和力学性能的变化,探讨了深冷处理工艺对铝合金轴瓦及低碳钢性能的影响。
通过硬度测试和拉伸实验发现力学性能变化与深冷处理工艺之间存在一定的联系。通过显微组织、力学性能、断口形貌的分析比较发现深冷处理促进了组织中第二相析出,通过XRD分析表明,深冷后材料内晶粒发生了转动。
经过深冷处理后,轴瓦和低碳钢板的性能得到明显提高。
Cryogenic treatment has wide application prospects not only in the fields of ferrous metal, nonferrous metal and alloy, but also in the fields of non-metal material, such as carbide, plastic material, metasilicate and so on. As a novel technique, cryogenic treatment has been used to improve the mechanical properties of materials and to prolong the life of tools and parts in the fields of machinery, aerospace, etc.
In this thesis, the mechanical properties and microstructures of the Al-alloy based Engine Bush (Y-serial and Jingling-serial) and CSP steel (SPCC,SPHC) before and after deep cryogenic treatment are studied.
The experimental results show that deep cryogenic treatment can obviously improve the hardness, strength of the bush Al alloys and the steel, which can be attributed to the fine precipitation of second phase particles and the grain preferred orientation. The relative experimental phenomena were explained and the mechanism was explored.
The as-treated Al-alloy based engine bush and CSP steel show excellent performance in this thesis.
