摘要
采用铸轧法制备了不同厚度的铜-铝-铜复合板,并分别采用拉伸试验、剥离试验、X射线衍射仪、能谱点分析(EDS)、扫描电镜(SEM)和能谱线扫描分析(EPMA)等对复合板力学性能、形貌和组成进行了检测。检测结果表明:界面层的主要组成物为α(Al)、Cu Al2、Cu9Al4。板厚从6 mm增大到14 mm时,界面层厚度和Cu、Al原子扩散程度均逐渐增加。抗拉强度从115 MPa增大到135 MPa,延伸率从25%增加至31%,剥离强度从30 N/mm增大至35 N/mm,剥离强度即为界面层结合强度。
Cu-Al-Cu compound plates of different thicknesses were fabricated by cast-rolled process. The mechanical property,micro-morphology and composition distribution of the casting rod interface were characterized by tensile test,X-ray diffraction( XRD),scanning electron microscope( SEM),energy dispersive spectrometry( EDS) and electron probe X-ray microanalysis( EPMA). The results show that the primary intermetallic compounds in the interface include α( Al),Cu Al2 and Cu9Al4. When the thickness of compound plate from 6 mm increases to 14 mm,the thickness of compound plate and the Cu,Al atom diffusion degree gradually increase. Tensile strength from 115 MPa increases to 135 MPa,elongation from 25% increases to31%,and peel strength from 30 N / mm increases to 35 N / mm. Peel strength is the bonding strength of interfacial layer.
