It is widely accepted that further development of Pb-free solder alloys for improved processing and in-service properties of next-generation electronics,can be accelerated through a fundamental understanding of phase transformation and micro-structure control in Pb-free solder joints.Advanced characterization techniques including synchrotron radiation provide a comprehensive toolset to measure the composition,crystallography,morphology,and properties of the major components of solder alloys.The research using such techniques is reviewed in detail including the characterization of the effects of micro-alloy additions on the microstructure and properties of Pb-free solder joints,especially those on the intermetallic phases.The discoveries outlined are of scientific and industrial relevance and have implications for new solder alloy composition design and the reliability of lead-free solder joints.

为了优化G115钢大型铸件正火及回火热处理制度,通过有限元方法,分析了正火和回火热处理工艺对铸件温度场分布的影响.结果表明,在正火过程中,铸件下端边缘处温度最高且升温速率最快,距上端约1/4处内表面温度最低,且升温速率最慢.在回火过程中,铸件的温度变化规律与正火过程相似.铸件下端边缘处在目标温度下的保温时间最长,上端约1/4截面厚度中心处的保温时间最短.结合加热速率、温差、加热效率及生产成本,正火优选工艺②,回火优选工艺③.采用优化后的热处理工艺所生产G115钢铸件的显微组织及力学性能均匀且明显高于CB2
利用有限元通用分析软件,模拟了大型焊接结构件焊后热处理前后构件的畸变分布.结果表明,焊态下结构件的最大畸变主要集中在中分面法兰处.通过模拟构件的总体畸变和结构法兰处的畸变分布,分析得出经过650℃保温6 h焊后热处理后,构件的总体畸变较小,且结构法兰处的畸变分布和焊后畸变分布呈较好的镜像对称性,可以有效改善焊后畸变,并有利于构件的尺寸稳定性.

H13钢试样经真空热处理后,分别对其进行渗氮和碳氮硫共渗处理,然后浸入700℃高温熔融铝液中进行腐蚀试验,并对腐蚀前后试样的截面组织形貌、质量损失及相成分进行了详细分析.结果表明:渗氮试样与碳氮硫共渗试样的渗层界面结合方式相似,渗层光滑致密,与基体分界较为平整.碳氮硫共渗试样的表面化合物区存在Fe3 N、Fe2 N、FeS、Fe3 C相,其中FeS相是典型的密排六方晶体结构,且硬度较高;渗氮试样表面化合物区存在Fe3 N、Fe2 N相,渗层的表面硬度高于碳氮硫共渗试样.在相同的腐蚀条件下,真空热处理试样的
研究了不同热处理工艺下汽车发动机气阀用节镍型高温合金的微观组织、硬度及力学性能.试验结果表明,在900～1100℃固溶温度范围内,该材料的晶粒尺寸随温度的升高逐渐增大,硬度逐渐降低,1050℃后晶粒长大明显、急剧粗化,固溶温度宜选择为1000～1050℃,以保证主要强化相必要的析出条件且具有适宜的晶粒度;在700～760℃时效温度范围内,该材料的强度随时效温度的升高而逐渐增强,但韧塑性逐渐降低.当固溶时效工艺为1020℃ ×30 min固溶(水冷)+720℃ ×4 h时效(空冷)时,该节镍型高温合金可获得
