Hardness testing is used to investigate the hardness of metallic material. Hardness tests are performed frequently because it is simple, inexpensive, and other mechanical properties can be estimated from hardness such as tensile strength. The basic concep... see more

In this study, Rockwell is used in material hardness examination. It caused by those characteristics. Those are, fast, away from human error, from this examination it can be known and compared the characteristics of nickel porosity before sentrifugal cast... see more

Stress relief annealing (SRA) is a process of releasing residual stresses contained in the material due to the welding process. The need for SRA is due to heterogeneous changes in the microstructure when the material is exposed to the heat of welding so t... see more

Taradejna Renata, Roszkowska Beata, Parzych Magdalena. Sklad kwasów tluszczowych i twardosc czekolad gorzkich o róznej zawartosci miazgi kakaowej = Fatty acid composition and hardness of dark chocolates with different content of cacao mass. Journal of Edu... see more

Current technological developments produce various kinds of innovations and creations in all things, which goal to facilitate all human activities. There are various kinds of tools for testing, ranging from tensile testing, compressive testing and hardnes... see more

This paper presented the investigation of failure mechanism of plastic shredding machine’s flange coupling which is made of cast steel. The machine unexpectedly stalled a few minutes after High-Density Polyethylene (HDPE) plastic bottles were fed into the... see more

AIM: This study aimed to verify the influence of oral environment and denture cleansers on the surface roughness and hardness of two different denture base materials. METHODS: A total of sixteen identical removable disc specimens (RDS) were processed. Eig... see more

There is expanded interest in the long-standing subject of the hardness properties of materials. A major part of such interest is due to the advent of nanoindentation hardness testing systems which have made available orders of magnitude increases in load... see more

The selection of the type of welding is determined based on the type of steel, the tensile strength which is influenced by the carbon content, and the shielding gas used to minimize the occurrence of welding defects. The effect of large/small gas flowrate... see more
