Metallurgy

Spheroidizing

Metals; Metallurgy

Any process of prolonged heating and slow cooling of steel which will convey the carbide content into rounded or spheroid form.

Stress relieving

Metals; Metallurgy

Heating to a suitable temperature, holding long enough to reduce residual stresses and then cooling slowly enough to minimise the development of new residual stresses.

Stress-corrosion cracking

Metals; Metallurgy

Failure by cracking under combined action or corrosion and stress, either external (applied) or internal (residual). Cracking may be either inter-granular or trans-granular, depends on metal and ...

Force per unit area. True stress denotes stress determined by measuring force and area at the same time. Conventional stress, as applied to tension and compression tests, is force divided by original ...

Stress relief

Metals; Metallurgy

Low temperature annealing for removing internal stresses, such as those resulting on a metal from work hardening or quenching.

Strain hardening

Metals; Metallurgy

An increase in hardness and strength caused by plastic deformation at temperatures lower than the re-crystallization range.

Strain

Metals; Metallurgy

A measure of the relative change in the size of a body. Linear strain is the change per unit length of a linear dimension. True (or natural) strain is the natural logarithm of the ratio of the length ...
