The results show that upper bainite of 9Cr2Mo Steel and GCr15 steel is feathery and the upper bainite carbide is lamellar or claviform. The upper bainite carbide distributes between the subunits of bainite ferrites by and large parallelly to the axis of bainite ferrites. Lower bainite of 9Cr2Mo Steel and GCr15 steel is in bamboo leaf shape and the lower bainite carbide is in shred or fibre shape. The lower bainite carbide distributes between the bainite ferrites, furthermore, the angles between lower bainite carbonide and the principal axis of the lower bainite ferrites are unequal.

Fine carbides precipitated from ferrite in 16-6 Cr-Mo, 16-2.5-6 Cr-Ni-Mo, and 16-5-6 Cr-Ni-Mo steels in the early stages of ageing are metastable, during prolonged heating they redissolve and are gradually replaced by χ-phase. Some residual carbides serve as the nuclei of the growing χ-phase. The structure of quenched 16-15-6 Cr-Ni-Mo steel is austenitic, during subsequent heating only M_6C and M_(23)C_6 mixed carbides are precipitated.

After the addition of carbon, the microhardness in the grain boundary is about 150 MPa higher than that in the grain. The fracture type of pure Mo is intergranular fracture, the grain boundary strength of Mo-C alloy is strengthened due to the addition of carbon and the fracture type is changed to transgranular fracture, transcrystalline fracture and a large number of cleavage planes and steps are observed on the bending fracture surface. But if the carbon content is too high, the carbide precipitation will be severe at grain boundaries and is deleterioated to the ductility of the alloy.
添加碳后,合金的晶界显微硬度比合金的晶内显微硬度高150MPa左右;纯钼的断裂方式以沿晶断裂为主,添加碳后,由于合金的晶界强度得到提高,合金的断裂方式变成以穿晶断裂为主,断口上有大量的解理面,具有明显的河流状花样和解理台阶,且塑性越好的断口,撕裂岭也越多;当添加的碳含量偏高时,在晶界处产生了大颗粒的碳化物,这种大颗粒的碳化物会降低合金的塑性。
