42CrMo/Q235层合轴的工艺,研究了轧制温度对层合轴界面微观组织,Cr元素的扩散和拉伸断口形貌等的影响,为改善层合轴界面处的结合质量提供了参考依据.层合材料结合界面力学性能是衡量复合材料质量的重要指标,是影响使用性能的一个重要因素.常用剪切强度,拉伸强度,冲击韧性和界面附近硬度等性能指标来衡量.层合材料在界面结合的过程中可能会产生某些缺陷,如局部产生融化,形成脆性相等,这些缺陷会导致层合材料界面硬化程... 050 ℃条件下轧制的试样显微硬度最大,1 100 ℃时次之,1 150 ℃时最小.图8所示为不同轧制温度下界面微观组织.由图8可知:随轧制温度的升高,有利于界面处金属的回复和动态再结晶,促使界面处的晶粒增大,动态再结晶的软化作用使界面处的显微硬度降低.Q235侧界面附近显微硬度大于Q235基体硬度,42CrMo侧界面附近显微硬度明显小于42CrMo基体硬度,这是因为钢中Cr元素是强碳合金元素,主......

steel, most studies on corrosion in water pollution have focused on corrosion impacted by the pollution of water bodies, corrosion laws and mechanism of alloy in polluted seawater, and so on [31-34... shown in Figure 1, Tables 2 and 3. The corrosion rate (CR) can be defined as CR=(Mend-Minitial)/S·t ......
