Distortion

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.
