摘　　要：针对起重机械轻量化材质铝合金的内应力,分别采用X射线衍射法、超声波法无损测试并对比分析铝合金ZL2025在铸态、挤压和轧制态下的内应力。结果表明,超声波法测得的ZL2025铝合金试样的内应力与X射线衍射法测得的结果具有良好的一致性,二者测量偏差不超过6%。For the internal stress of lightweight aluminum alloy of crane,the X-ray diffraction and ultrasonic method was used to test the internal stress of aluminum alloy ZL2025 in the as-cast,extruded and rolled state respectively.The results show that the internal stress of ZL2025 aluminum alloy samples measured by ultrasonic method is consistent with that measured by X-ray diffraction method,the deviation between which is less than 6%.
