Figure 2: The stress-strain diagram clearly shows the differing characters of TRIP and TWIP steel. TRIP steel can resist high stresses without deforming. TWIP steel deforms with low stresses, but does not break until strain reaches around 90 percent.

Microtensile stress-strain curves for submicrometer nanocrystalline aluminum thin films showing two distinct behaviors.7 The curve with the highest strength, gradual deviation from plasticity, and limited ductility is representative of a specimen that maintains its nanocrystalline grain size. By contrast, specimens observed to undergo stress-assisted room-temperature grain growth exhibit lower yield strengths and regions of extended plasticity.

Increasing the annealing time decreases the recrystallization temperature for the start of recrystallization.During recrystallization stage, there is a significant drop in tensile strength, hardness and a large increase in the ductility of the material (See Figure 1).

Figure 1. Effect of annealing on tensile strength, hardness, ductility and grain size.
