The results show that the microstructure of Fe-28Al-5Cr-0.06B alloy refines by using stainless steel mold cooling method, the tensile strength of alloy increases 29 MPa, the hardness increases slightly but the elongation decreases a little at the same condition except, the impact fracture transform intercrystalline fracture into intercrystalline and transcrystalline mixed fracture.

结果表明：采用不锈钢金属型冷却，可以细化合金的铸态组织；在其他工艺相同的条件下，合金的抗拉强度提高了29 MPa，硬度有所增加，伸长率稍有下降；合金的冲击断口由沿晶断裂向沿晶＋穿晶混合型断裂转变。

With the aid of the experiment, crack formation and its expand pattern of ZTA ceramics under ultrasonic vibration were analyzed, its fracture criterion was established and the experiment results showed that intercrystalline fracture is the main fracture pattern of ZTA ceramics under common grinding, and transcrystalline fracture is the main fracture pattern of ZTA ceramics under TDUVAG, and the finding add to evidence showing that TDUVAG has better material removal property.

基于该方法分析具有预制裂纹的ZTA纳米复相陶瓷材料在超声振动条件下裂纹扩展方式，确立其断裂判据，通过该断裂模拟试验得出：沿晶断裂是普通磨削主要的断裂模式，而穿晶断裂是二维磨削主要的断裂模式，进一步证明二维磨削具有较好的材料去除特性。

The tensile tests show that the yielding strength and fracture strength increase with increasing Co content. The fracture mechanism of martensite phase is transcrystalline fracture, and the γ phase is gliding fracture, it proves that the γ phase improves the toughness of experimental alloys

断口观察发现，基体相为解理断裂，小尺寸的γ相被裂纹绕过或被整体拔出，大尺寸的γ相被拉长、撕裂或整体拔出，说明γ相有利于改善合金韧性，但增韧效果受到γ相尺寸的影响

SEM analysis finds that the fractures are intercrystalline plus quasi-cleavage fractures under quasi-motionless state;with the increase of stress intensity factor,fractureschange from transcrystalline quasieleavage fractutes to microvoid-coalescence dimple plus cleavage frac-tures,The increase of fracture toughHess of 8090Al-Li alloy under high stress intensity factor is associ-ated with the deformation mechanism and the change of precipitation Free Zone of grain boundary.

扫描电镜分析发现，准静态下的断裂为沿晶和准解理混合断口；随着应力强度因于的增加，断裂从准解理断裂过渡到准解理和显微空穴聚集的韧窝断裂舶混合断口。高应力强度因于率下断裂韧度的提高与其变形机制和晶界无沉淀区的变化有关。
