Abstract Distortion can be defined as an irreversible and usually unpredictable dimensional change in a component due to heat treatment processing or temperature variations and loading in service. This chapter describes two types of distortions, namely size and shape distortions. It addresses how distortion can be managed by controlling. The chapter discusses the cause and effect of distortion during nitriding, the processes involved in stock removal prior to nitriding, and the criteria for postmachining operations.

The dimensional change of tooth profile by heat treatment of helical gear was investigated by experimental and numerical approaches. Especially, the three-dimensional elasto-plastic finite element (FE) simulation was adopted to analyze the elastic deformation during load, unloading, ejecting of workpiece. Quenching simulation was also carried out to investigate the change of tooth profile on the forged gear. In experiments, the amount of elastic deformation of the forged gear was quantitatively determined by comparing the tooth profiles on the forged gear and die. The dimensional change of the forged gear tooth after quenching was also evaluated from the comparision of the cold forged and quenched gear teeth. From experimental works, it was found that the amounts of dimensional changes after forging and quenching of helical gear are 10 and 10 μm, respectively.
