    en.wikipedia.org/wiki/Tin-silver-copper

    Tin-silver-copper (Sn-Ag-Cu, also known as SAC), is a lead-free alloy commonly used for electronic solder.It is the main choice for lead-free surface-mount technology (SMT) assembly in the industry, [1] as it is near eutectic, with adequate thermal fatigue properties, strength, and wettability. [2]

    Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.

  7. Tensile testing - Wikipedia

    en.wikipedia.org/wiki/Tensile_testing

    Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength , breaking strength , maximum elongation and reduction in area. [ 2 ]

  8. Diametral compression test - Wikipedia

    en.wikipedia.org/wiki/Diametral_compression_test

    A diametral compression test involves applying a stress load or force to the point where a material object is split in half (down the diameter of the object). [1] This test indirectly measures the tensile property of a material object, as the molecules of the material are pushed apart in opposite directions, similar to what happens to molecules in a direct tensile strength test.

  9. Strain hardening exponent - Wikipedia

    en.wikipedia.org/wiki/Strain_hardening_exponent

    In one study, strain hardening exponent values extracted from tensile data from 58 steel pipes from natural gas pipelines were found to range from 0.08 to 0.25, [1] with the lower end of the range dominated by high-strength low alloy steels and the upper end of the range mostly normalized steels.
