摘要
对铝镁合金铸件疏松、偏析类缺陷种类、形成机理及其安全使用风险进行了系统的分析,通过X射线、电镜扫描观察铸件不同程度的疏松、偏析组织的微观形貌,并结合力学性能、化学成分检测数据分析评估各类型缺陷对产品使用性能的影响,指出铝镁合金铸件疏松、偏析缺陷安全使用的判定方法,为产品的检测和质量保证提供参考.
Abstract
The types,formation mechanisms and safe use risks of loose and segregation defects in Al-Mg alloy castings were systematically analyzed.The micro-morphology of loose and segregation structures in different degrees of castings were observed by X-ray and electron microscope scanning,and the influence of various types of defects on product performance was evaluated by combining mechanical properties and chemical composition detection data.The determination methods for the safe use of loose and segregation defects in aluminum-magnesium alloy castings are pointed out to provide reference for product testing and quality assurance.
