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。

In high ─ speed steel, molybdenum can replace parts of tungsten.

钼铁是钼与铁的合金，它的主要用途是在炼钢中作为钼元素的加入剂，钢中加入钼可使钢具有均匀的细晶组织，并提高钢的淬透性，有利于消除回火脆性，在高速钢中，钼可代替一部分钨，钼同其他合金元素配合在一起广泛地应用于生产不锈钢、耐热钢、耐酸钢和工具钢，以及具有特殊物理性能的合金，钼加于铸铁里可增大其强度和耐磨性。
