Y
Yellow Brass
65% copper and 35% zinc. Also known as High
Brass. A copper-zinc alloy, named for its yellow hue. Formerly a very popular
alloy, but now largely replaced by Cartridge Brass.
Yield
The ratio of the quantity of finished shipments to the total raw steel produced,
adjusted for changes in inventory and any slabs that are purchased from outside.
Yield has significantly improved during the past decade, primarily as the
result of the industry's conversion to continually cast steel, whose yield is
superior to that of traditional ingot teeming.
Yield Point
The load per unit of original cross section at which, in soft steel, a marked
increase in deformation occurs without increase in load.
Yield Strength (YS)
The stress at which a material exhibits a
specified limiting deviation from the proportionality of stress to strain. The
deviation is expressed in terms of strain. Also known as proof stress.
Young's Modulus
The coefficient of elasticity of stretching.
For a stretched wire, Young's Modulus is the ratio of the stretching force per
unit cross-sectional area to the elongation per unit length. The values of
Young's Modulus for metals are of the order 10(12) dynes per square cm.
