ductility

[duktil′itē]
the property of a material of having a large elastic range and tending to deform before failing from stress.

ductility (duktil´itē),

n the property of a material that allows permanent deformation under tension without rupture. It is measured as a percentage increase in length on rupture compared with original length and is termed percentage elongation, or elongation.

Scanning electron fractography near the crack origin area showed a cleavage-type brittle fracture with flat grain facets and a river pattern typical of a steel fracture below the ductile-brittle transition temperatures (see Figure 5).
Below this temperature, known as the ductile-brittle transition temperature (DBTT), the material breaks in a brittle (usually low impact energy) manner; above this temperature, the material breaks in a ductile (usually high impact energy) fashion.
With these blends, the impact strength was not markedly affected by the presence of a weld line, above or below the ductile-brittle transition temperature of PP.
