Ms point is higher at the micro-area of lower carbon density, and the martensite first form in that area during the quenching. Ms point is lower at the micro-area of higher carbon density, and the martensite form subsequently. The martensite transformation is non-isothermal due to the difference of formation temperatures, and therefore martensite lamella can not grow larger by penetrating different area of carbon density. Therefore the martensite is refined . Furthermore, as mentioned above, the strength and hardness of 40Cr steel increases when grains become fine, which is in agreement with the Reference .
Martensite begins to be large above 920℃ quenched and results in decrease of strength and hardness. The strength and hardness of 40Cr steel have the maximum value at 920℃ by zero holding time quenching. Compared with the conventional quenching, the hardness and the tensile strength of samples 860℃×20min quenched are listed in Tab. 2. It can be seen that the mechanical properties of samples “zero time holding” Quenched are better than that of samples 860℃×20min quenched. “Zero time holding” Quenching process for 40Cr steel is feasible.
By comparing the advantages and disadvantages of various cases, this paper will review several major evaluation methods of lapping uniformity to improve the evaluation system. 48 Digital Design and Manufacturing Technology II Lapping trajectory is the relative kinematic trajectory between abrasive particle and the workpiece during the lapping process. Usually, it can be classified into two kinds, one is the kinematic trajectory of a certain point on the workpiece surface relative to the pad, and the other is the kinematic trajectory of abrasive relative to the workpiece.
