过渡金属碳化物的杨氏模量已从其评估的热性能计算，以解释为什么钢和白色铸铁的模量只能通过改变成分或热处理轻微改变。结果表明，渗碳体的模量（200 GN m-2）与纯铁素体的计算值（215 GN m-2）几乎相同。预测的系统变化的模量与结构和位置在周期表中合理化以前的孤立的实验观察，并确认第IV族元素的MC碳化物应该有最强大的增强效果在其母体金属的基质。MST/1909
The Young's modulus of transition metal carbides has been calculated from their assessed thermal properties to explain why the modulus of steels and white cast irons can be only marginally altered by changes in composition or heat treatment. It is shown that the modulus of cementite (200 GN m−2) is virtually identical to the value calculated for pure ferrite (215 GN m−2). The predicted systematic variation for the modulus both with structure and position in the periodic table rationalises previous isolated experimental observations and confirms that the MC carbides of the group IV elements should have the most powerful strengthening effect in a matrix of their parent metal.
