Thanks to the collaboration between two laboratories, we present different techniques to measure thermal diffusivity. A brief description of any technique both in the experimental layout and in the processing algorithms is given. Results obtained on samples cut from the same block of stainless steel AISI 304, are reported. Uncertainty evaluation of any measurement is reported as well.

Additive technologies provide a means for repair of various failure modes associated with material degradation occurring during use in aggressive environments. Possible strategies AISI 4340 steel using 316L deposited by additive friction stir deposition (AFSD) were evaluated under this research metallography, microhardness, and wear mechanical testing. Two geometries investigated: groove-fillin...

The monotonic and cyclic deformation behavior of ultrafine-grained metastable austenitic steel AISI 304L, produced by severe plastic deformation, was investigated. Under monotonic loading, the martensitic phase transformation in the ultrafine-grained state is strongly favored. Under cyclic loading, the martensitic transformation behavior is similar to the coarse-grained condition, but the cycli...

The aim of this research is to study the machinability aspects hardened AISI 4340 High Strength Low Alloy (HSLA) steel (50 ± 2 HRC (Hardness Rockwell C)). experimental investigation using coated carbide inserts carried out during dry hard milling process in a sustainable environment. input parameters are speed, feed rate and depth cut responses Average surface Roughness (Ra) Material Removal Ra...

silica refractory bricks are used especially in the metallurgical industries, due to desirable properties suchas high melting point, rigidity, and high temperatures strength. in this research, different amount of sicwere added to silica refractory containing different binders such as borax, boric acid, calcium nitride,sodium tri poly phosphate, sodium hexa meta phosphate (shmp) and lime. physic...
