Influence of heating parameters on flow stress curves of low-alloy Mn-Ti-B steel [PDF]

, 2018
Influence of the initial grain size on hot deformation behavior of the low-alloy Mn-Ti-B steel was investigated. The uniaxial compression tests were performed in range of the deformation temperatures of 900-1200 degrees C and strain rates of 0.1-10 s(-1).

Tensile Testing with Cyclic Strain Holding to Analyze Dynamic Recrystallization of Pure Lead

Advances in Materials Science and Engineering, 2014
We analyzed the dynamic recrystallization of pure lead by tensile testing with cyclic strain holding at room temperature. The specimens were held at an identical strain and subsequently reloaded, providing the strength before and after the strain holding
