摘要
对轨道车辆用6005和7005(919)铝合金材料的焊接接头微区性能进行了试验研究,对焊接接头微区性能的变化规律进行了讨论。结果表明,微区剪切试验特别适用于焊接接头的微区性能研究,其测量结果精确可靠,可作为材料选择及结构设计与工艺评定的依据。
The properties of welded joints micro-zones in6005and7005aluminium alloy profiles used for train are studied.The properties of welded jonits micro-zones are discussed.The results show that the shearing tests of micro-zones are especially applied to researching properties of welded joints micro-zones.
