Case hardening, at its simplest, is the process of toughening the surface of a metal by infusing elements into the outer layer, all while retaining the softer, ductile core. This dual nature ensures wear resistance on the outside .Hardening is a metallurgical metalworking process used to increase the hardness of a metal. The process starts with the heating of metal at a critical transformation temperature and quenches in a molten salt bath/water.
The tempering process consists of three basic steps: Heating: steel is brought to high temperatures to change its internal structure. During this stage, the steel acquires the structure of austenite. Temperature maintenance (Austenization): . The formability is the capability of sheet metal to undergo plastic deformation to a given shape without defects.

Study with Quizlet and memorize flashcards containing terms like What are the differences between bulk deformation processes and sheet metal processes?, Extrusion is a fundamental shaping process. Describe it, Why is the term pressworking often used for sheet metal processes? and more. Four typologies of hardening may arise during sheet forming processes (Fig. 1): (i) isotropic hardening, which refers to the proportional expansion of the initial yield surface; (ii) kinematic hardening, if the deforming material shows a yield surface that does not change in form and size, but translates in the stress space; (iii) rotational . The equivalent hardening responses are expressed by single material hardening curves and their hardening exponents are taken as parameters to approximate sheet metal viscoplasticity. This method therefore makes it possible to develop early-stage design guidelines that consider different materials and stamping processes. Case hardening is a key step in the manufacturing process of a wide variety of products. Sheet metal screws need case hardening to penetrate steel without shattering. Lock components need to be hardened to protect them from damage over time. And jet engine parts often require hardening to ensure they’re reliable under extreme conditions.

1. R. Ganesh Narayanan, IITG Metal forming processes Metal forming: Large set of manufacturing processes in which the material is deformed plastically to take the shape of the die geometry. The tools used for such deformation are called die, punch etc. depending on the type of process. Plastic deformation: Stresses beyond yield strength of the workpiece material . Cold working techniques include processes such as rolling, drawing, and extrusion, which are commonly used in the production of sheet metal, wires, and other products. These processes induce significant plastic deformation in the metal, leading to .

Creating a draw panel or a panel from the first forming station of a progressive die involves straining the sheet metal, leading to work hardening in the formed areas. Moving those work-hardened areas in subsequent operations requires greater force than required to initially form the flat sheet. . Typically, the selection process also . Sheet metal fabrication is a technology in which flat sheet metal is converted into different parts. However, in the case of tube fabrication, metal pipes or tubes are formed by curving the metals at different angles. . Case-hardened condition refers to the state of a metal part after the case-hardening process, in which its outer surfaces .

The process of the loss of stability is analysed for sheet metal subjected to biaxial tension when the ratio of the principal stresses 0.5 ⩽ σ 2 /σ 1 ⩽ 1. The loss of stability manifests itself by a groove running in a direction perpendicular to the larger principal stress. In this groove local strains begin to concentrate gradually. In the late 1960s, pioneer works by Keeler [] and Goodwin [] established the initial procedures for characterizing metal sheet formability based on the use of circle grid analysis (CGA) techniques, allowing for the determination of the in-plane strains on the surface of sheet metal formed parts.Later, in the early 1980s, Embury and Duncan [] introduced what they . The present paper aims at analysing the sheet metal formability through several isotropic and kinematic hardening models.
