The fracture mechanism of totally austenite TWIP steel (steel 5#) is: the moving of dislocations is blocked by twin boundary during deformation. Micro-voids nucleate at boundary of deformation twins by the interaction between deformation twins and dislocations. Micro-voids are formation, growth, coalescence and break by the stress concentration during deformation.

全奥氏体的TWIP钢（如5＃钢）的断裂机制为：形变过程中位错的运动受孪晶界的阻碍，形变孪晶与位错的交互作用使微孔形核于孪晶界处，应力集中使微孔长大、聚合直至材料发生断裂。

The fracture mechanism of the whole austenite TWIP steel (steel 5#) was that the moving of dislocations was blocked by twin boundary during deformation, the microvoids nucleated at boundary of deformed twins by the interaction between deformed twins and dislocations, the microvoids grew, got together and broke by the stress concentration during deformation.

全奥氏体的TWIP钢（2＃钢）的断裂机制为：形变过程中位错的运动受孪晶界的阻碍，形变孪晶与位错的交互作用使微孔形核于孪晶界处，应力集中使微孔长大、聚合直至材料发生断裂。

The fracture mechanism of TWIP steel (steel1#) which contained second phase was that the microvoids nucleated due to the decreasing of binding force between austenite and second-phase or the second phase dehiscence caused by strain hardening, then the microvoids grew, got together and broke by the stress concentration during deformation.

含有第二相的TWIP钢（1＃钢）的断裂机制为：第二相和奥氏体相界面聚合力的减弱或第二相本身加工硬化导致的开裂促使微孔形核，形变过程中产生的应力集中使微孔长大、聚合直至发生断裂。

The fracture mechanism of TWIP steel (steel1#) which contains second-phase is: micro-voids nucleate due to binding force weaken between austenite and second-phase or second-phase dehiscence itself caused by strain-hardening. Micro-voids are formation, growth, coalescence and break by the stress concentration during deformation.

含有第二相的TWIP钢（如1＃钢）的断裂机制为：第二相和奥氏体相界面聚合力的减弱或第二相本身加工硬化导致的开裂促使微孔形核，形变过程中产生的应力集中使微孔长大、聚合直至发生断裂。
