Affect The Mechanical Properties Of The Steel In The Annealed Condition

Sep 07, 2015

Due to the addition of alloying elements reduces the carbon content of the eutectoid point, the C curve to the right, so that the proportion of the organization pearlite increases, the pearlite lamellar distance decreases, which increases the strength of steel, plastic decline. But in the annealed condition, Alloy no great advantage.

Due to increased stability of supercooled austenite, alloy available at normalizing state plies distance smaller pearlite, or bainite or martensite, thereby greatly increased strength. Greater strengthening effect Mn, Cr, Cu, and Si, Al, V, Mo, etc. In general content (e.g., the actual content of the general structural steel) under the influence is small.
