In this case, an established link between materials parameters and P-h curves can naturally lead to direct hardness estimation from the materials parameters (such as yield stress and work hardening coefficients).
Materials and Experimental The material used were steel.
Similar agreement has been found in other materials (within 5% error range).

Local surface alloying of metallic materials by laser is an issue of interest in the scientific world and materials engineering.
In case of large differences in the melting temperature of the materials the phenomenon of segregation of the alloying materials may occur in the laser melted pool, for example in case of CoCr alloying.

Generally, most of the 2D monolayer materials have no band gap that limited their applications at electronics.
GeH is a new generation of monolayer stabilized materials.
This article is instructive for a deep study of the properties of GeH materials.
This method has been successfully applied to the strain study of other two dimensional materials [12-13].
