    Alloying lead - tin solders with bismuth and indium lowers the solder's melting temperature and yield strength .
  • The strain-rate sensitivity of high-strength high-toughness steels.
    This is in distinct contrast to recent results on a very different metallic alloy , eutectic lead - tin solder, where the same range in strain-rates causes a 100% increase in yield - strength .
  • ZASMHBA0001831
    nium alloys, nickel-copper alloys, and aluminum alloys are stressed while in contact with low-melting metals, including lead , tin , cadmium, lithium, indium, gallium, and mercury, they may be embrittled and fracture at a stress below the yield strength of the alloy .

Liquid-metal embrittlement has been observed for plain-carbon and low- alloy steels exposed to liquid cadmium, lithium, brass, aluminium bronze, copper, zinc, lead - tin ' solders, mercury, tin, antimony, tellurium, lead, and indium.
  • Analysis of thermomechanical interactions in a miniature solder system under cyclic fatigue loading
    A recent literature review has been conducted to study the rate dependence of yield strength of eutectic and near-eutectic lead - tin solder alloys16 for deter- miningthetemperature-dependentmaterialconstants of D and p in Eq. 2. The experimental stress-strain data for the eutectic Pb37-Sn63 solder alloy pre- sented in Ref. 1...
  • ZEMEA2008P597
    The reader may want to refer to Section 6.3.2 in Chapter 6, "Phase Diagrams," for a discussion of solders in relation to the lead - tin eutectic phase diagram. Silver can be added to lead-tin solders, yielding solders with good tensile, creep, and shear strengths . Lead is very soft and is often alloyed with antimony, tin, calcium, and arsenic to give it...
