The results show that, most annealing twin microstruc- ture distribute in austenite matrix of annealed sample, and the deformation twin formed during tensile strain make the sample attain high strength and high plasticity.

Microstructure characteristics of adiabatic shear deformation and deformation twins on both sides of QBe2 and T2 were investigated by means of optical microscope and SEM electronic backscatter diffraction techniques.

A new type of intersection mechanism of deformation twins with α2 plates in γ TiAl based alloy deformed at room temperature was 利用透射电镜在室温变形的γ-TiAl基合金中研究了一种新的形变孪晶与α2片的交截机制。

The effect of deformation twins on fatigue property of 50CrV4 spring steel was studied by comparing microstructures with different fatigue life,and the law of fatigue fracture was analyzed.

On the deformation process the annealing twins transform into deformation twins , which is TWIP effect, and so th.
