摘要
针对当前在材料应用方面对高韧性铜镍合金的需求,在以往研究的基础上,对铜镍合金中掺入铁、锰和锌等元素,并对比其与其他铜合金的性能。结果表明,在热挤压阶段,掺入部分微量元素后,在不同应变温度和应变速率下,铜镍合金的应变力随着温度和速率的增加而不断提高。当温度和速率增加到一定值后,应力开始趋于平稳。同时在热锻阶段,在不同温度和处理工艺下,随着温度的升高,其硬度在2h时达到最大,并且时效处理温度为550℃。最后通过在耐磨性方面的对比,验证了本文制备合金的耐磨性能要高于传统的合金,验证本文制备材料的可行性。
In view of the current demand for high toughness Cu-Ni alloys in material applications,iron,manganese and zinc were added into Cu-Ni alloys on the basis of previous studies,and the properties of Cu-Ni alloys were compared with other Cu-Ni alloys.The results show that the strain stress of Cu-Ni alloy increases with the increase of temperature and strain rate at different strain temperature and strain rate after add.ing some trace elements during extrusion stage.When the temperature and strain rate increase to a certain value,the stress starts to stabilize.At the same time,in the hot forging stage,at different temperatures and treatment process,the hardness reaches to the maximum at 2 h,with the temperature increasing,and the aging treatment temperature is 550℃.Finally,by comparing the wear resistance,it is verified that the wear resistance of the alloy prepared in this paper is higher than that of the traditional alloy,and the feasibility of the material prepared in this paper is verified.
