ductiliteetti
Ductiliteetti, or ductility in materials science, is the ability of a solid to undergo significant plastic deformation before fracture under tensile loading. It is commonly quantified by measurements taken in a tensile test, such as elongation at fracture and reduction of area. Materials with high ductility can be drawn into wires or formed into complex shapes without breaking, while brittle materials fracture with little or no plastic deformation.
The underlying mechanism lies in the mobility of dislocations within a material’s crystal lattice. In metals,
Measurement and interpretation: A standard tensile test provides percent elongation and reduction of area to quantify
Applications: Ductility is crucial for forming operations such as drawing, extrusion, and bending. Alloys are designed
