Phase Diagrams and Computational Thermodynamics - Solder Systems predicts melting temperatures and freezing ranges of lead-free solders which are used to remove lead-containing components from commercial products. This database also shows the effects of non-equilibrium solidification. Also included is a collection of calculated binary and ternary systems that are relevant to solders.

Recommended values are provided for chemical thermodynamic properties of inorganic substances and for organic substances usually containing only one or two carbon atoms. Where available, values are given for the enthalpy of formation, Gibbs energy of formation, entropy, and heat capacity at 298.15 K (25 degrees C), the enthalpy difference between 298.15 and 0 K and the enthalpy of formation at 0 K. All values are given in SI units and are for a standard state pressure of 100 000 pascal.

NTRL (National Technical Reports Library) offers a public interface for accessing authenticated government technical reports in the U.S.Department of Commerce NTIS (National Technical Information Service) database.The National Technical Information Service is a large central resource for U.S.government - funded scientific, technical, engineering, and business related information.The database of more than 3 million publications provides links to over 800, 000 full - text technical reports in 350 subject areas.Over 195, 000 brief records have been added for pre-1964 information.(Updated regul
