Journal ArticleDOI
Hygrothermal effects of epoxy resin. Part I: the nature of water in epoxy
Jiming Zhou,J. P. Lucas +1 more
TL;DR: In this paper, the authors assessed the nature of sorbed water and the related hygrothermal effects in epoxy resins and found that water molecules bind with epoxy resin through hydrogen bonding.
Journal ArticleDOI
Hygrothermal effects of epoxy resin. Part II : Variations of glass transition temperature
Jiming Zhou,J. P. Lucas +1 more
TL;DR: In this article, three epoxy systems (DGEBA+mPDA, TGDDM+DDS, and Fiberite 934TM) were used to investigate glass transition temperature variation of epoxy under hygrothermal environment exposure.
Journal ArticleDOI
Characterization of the growth of intermetallic interfacial layers of Sn-Ag and Sn-Pb eutectic solders and their composite solders on Cu substrate during isothermal long-term aging
TL;DR: In this paper, the growth kinetics of intermetallic interfacial layers formed between solder and the Cu substrate was characterized, and the effect of in-situ Cu6Sn5 intermetall phases on the growth rate was discussed.
Journal ArticleDOI
The effects of a water environment on anomalous absorption behavior in graphite/epoxy composites
Jiming Zhou,J. P. Lucas +1 more
TL;DR: In this article, the effects of a water environment on moisture absorption characteristics of a unidirectional T300/934 graphite/epoxy composite material have been investigated by the measurement and analysis of weight change, hygrothermal induced expansion, surface crack formation, and surface mass loss.
Journal ArticleDOI
Grain-boundary character and grain growth in bulk tin and bulk lead-free solder alloys
Adwait U. Telang,Thomas R. Bieler,J. P. Lucas,K. N. Subramanian,L.P. Lehman,Y. Xing,Eric J. Cotts +6 more
TL;DR: In this article, the effects of alloy composition variations and cooling rates on microstructural stability and deformation processes were investigated in a pure-tin ingot and a reflowed sample.
