MICROHARDNESS OF TOOTH ENAMEL WITH DIFFERENT LEVEL OF RESISTANCE
This study about the microhardness of tooth enamel is evaluated by nanoidentation. The data indicate that the average microhardness of the enamel of the permanent teeth in the region of the equator is 5,75±0,06 Gpa, modulus of elasticity - 97,72±0,74 ...

Ion-beam nitriding of steels [PDF]
The application of the ion beam technique to the nitriding of steels is described. It is indicated that the technique can be successfully applied to nitriding. Some of the structural changes obtained by this technique are similar to those obtained by ion

A computationally designed, cobalt‐free maraging steel tailored for additive manufacturing achieves an ultra‐high tensile strength of 2.3 GPa with 5.7% elongation. This exceptional strength‐ductility synergy stems from high‐density core‐shell Ni3Ti/NiAl nanoprecipitates, a crack‐resistant composition, and a fine equiaxed grain structure enabled by ...

Effect of grinding on the fatigue life of titanium alloy (5 Al-2.5 Sn) under dry and wet conditions [PDF]
The principal factors in the performance of aerospace materials are strength-to-weight ratio, fatigue life, fracture toughness, survivability and, of course, reliability. Machining processes and, in particular, grinding under adverse conditions have been
