Deformation of Metals and Its Types Metallurgy

For example cold rolled steel is strengthened by applying the principle of work hardening. Running a bar of steel through rollers compresses it laterally and causes it to elongate. Elongation causes an increase in tensile yield strength, but lateral compression causes a decrease in tensile yield strength across the bar. Elastic Aftereffect:

$\begingroup$ It says right in the article. For hot rolled carbon steels, the number quoted in the designation is the value of yield strength for material up to 16 mm thick. Designers should note that yield strength reduces with increasing plate or section thickness (thinner material is worked more than thick material and working increases the strength).

Metallurgy Matters Making steels stronger

Oct 09, 2003 Metallurgy Matters: Making steels stronger. As we get into modifying a steel's strength and hardness, keep a couple things in mind. First, don't confuse hardness with hardenability. A steel's maximum hardness is a function of its carbon content: more carbon, more hardness. Hardenability, on the other hand, refers to the amount of martensite ...

Separation of valuable elements from steel making slag by

Jul 01, 2020 The yield above 500 C tended to decrease with increasing temperature. The temperature range 400–500 C, in which the largest yield was previously observed in carbo-chlorination, shifted to 300–400 C for chlorination (800 C). These yield-changing behaviors with temperature did not depend on slag type and were almost the same.

Influence of carbon on hardness and strength of steels

Jun 30, 2018 With increasing carbon, the hardness and strength of unalloyed steels increases. Above a content of 0.8% C, the strength decreases.
