Metallurgical Engineering Iron Making In Metallurgy Difficulty: Medium

Metal powders treatment is refer to Electromagnetic stirring of the liquid steel in continuous casting is primarily used to Air hardening steels are basically If the friction is increased by two, then the reduction decreases by From an alloy, two specimens are machined and tested separately under tension and compression. The engineering stress-strain curves as well as the true stress-true strain curves for tension and compression are plotted in the same diagram. Identify the correct statements: P. The engineering stress-strain curves in tension and compression are identical. Q. The true stress-true strain curve in compression is lower than the true stresstrue strain curve in tension due to Bauschinger effect. R. The true stress-true strain curve in tension is above the corresponding engineering stress-strain, curve. S. The true stress-true strain curve in tension and compression are identical.
