Hard coatings with less adhesion are required in forming field. Interfacial phenomena between tool and material during forming are difficult to be observed. Therefore, an atomistic-calculation analysis of the interaction between heterogeneous atoms, derived from first-principles electronic-state calculations, has proposed. In the case of TiN coated surface, Ti-Al, N-Al potentials were derived. The Al-Al potential for the Al atoms close to the TiN surface was also extracted. Using the derived interatomic potentials, a molecular dynamics calculation simulating a kind of ironing-type forming process was carried out. The change in number and arrangement of the adhered atoms during ironing were compared with each other in the three (TiN, VC, CrN) ceramic coatings.

Micro/Meso-Scale Metal Forming Invited International conference

ICMSE-RAC 2019 (International Conference on Material Science & Engineering Recent Advances and Challenges) CMRDI（Central Metallurgical Research and Development Institute） & E-JUST (Egypt-Japan University of Science and Technology)
Event date： 2019.03
Language：English Presentation type：Oral presentation (keynote)
Venue：Sofitel El Gezira, Cairo, Egypt
Micro/meso-scale metal forming treats the size effects in forming of small-sized metal parts such as the anisotropy in plastic deformation and nonuniform and nonconstant in friction between the material and the tool. The anisotropy in plastic deformation is discussed by comparing the result of an ECAP (equal-channel angular pressing) process with the calculated results of an FEM considering crystal plasticity. The change in friction is measured by using a direct-measurement apparatus during forming.

The change in the friction character during forming strongly depends on adhesion processes. The process is captured by measuring a distribution of the contact potential difference (CPD) of the tool surface after an injection upsetting. The change in CPD of TiN-coated die surface is compared with that of non-coated die surface.

Hard coatings with smaller amount of adhesion during and after forming are required in this field. Interfacial phenomena between tool and material during forming are difficult to be observed by experiments. Therefore, an atomistic-calculation analysis of the interaction between heterogeneous atoms, derived from first-principles electronic-state calculations, has been utilized for the study of adhesion during forming. Before constructing the interaction between 15 ceramic coatings (tool) and aluminum (material), calculated bulk and surface properties of the ceramics are verified by the reported experimental lattice parameter, bulk modulus and work function. Using the derived inter-atomic potentials for the interfaces between the constituent atom in transition metal carbides or nitrides and the Al atom, a molecular dynamics calculation with the geometry of ironing-type forming (the inclined tool moves over the material of which the bottom is fixed) is carried out. The comparison between the speed of a tool and an Al atom identifies whether the Al atom adheres on the tool. The change in number and distribution of the adhered atoms during ironing are compared with all the 15 combinations.
The number of adhered atoms in the first layer on the tools increases and saturates immediately. The behavior is common in all combinations. The change in number of adhered atoms in the second layer onwards shows wide variations.
The distribution of adhered atoms is analyzed by using a radial distribution function. The increase of the number of adhered atoms in the second layer onwards (the growth of adhesion) depends on the structure of the first layer of adhered Al atoms. If the location of the first nearest neighbor atom of Al first layer is equal to the second nearest neighbor atom of the tool surface, then growth of adhesion occurs. -

Information about distribution and change in friction during forming is required to construct a prediction model. The small deflection of a thin part fabricated at the other side of a flat tool surface is detected using laser reflection to decompose the normal and horizontal (frictional) forces. The locus of laser reflection on a detector showed both components. The values estimated from the locus were fairly close to the measured forces.
