The Journal of Hydraulic and Environmental Engineering (JHEE) was granted a license selection 498/GP-BTTTT because of the Ministry of Information and Communications on October seventeen, 2022 (changing the old license amount 158/GP-BVHTT dated May perhaps 8, 2003); ISSN code: 1859-3941.The journal is included in the list of journals for which do the job points are calculated through the Condition Professorship Council. The Council with the Professorship in Hydraulic Engineering awards function factors from 0-1.0; the Council for that Professorship in Mechanics awards do the job points from 0-0.5; the Council for your Professorship in Mechanical Dynamics awards operate details from 0-0.five; the Council with the Professorship in Transportation awards work points from 0-0.5.
On this examine, metal abrasion experiments ended up done on an computerized grinding device for stainless steel 304. Experiments had been carried out at distinct grinding moments for scenarios of warmth-dealt with samples and samples inside their offer condition. The martensite stage transformation through grinding was analyzed by microstructure observation effects and floor hardness, microhardness measurements. The investigation benefits show which the abrasion resistance of SUS304 metal enhances substantially once the sample is quenched in water even though the area hardness won't raise. This phenomenon might be described by the appearance of your martensite period by way of a phase transformation system resulting from plastic deformation of the material's surface layer.
Observation success demonstrate that right after grinding, a substantial amount of martensite period appears over the floor of heat-dealt with samples. The macro surface area hardness of the metal doesn't maximize, but microhardness in several areas demonstrates a clear change, particularly in locations with large concentrations of martensite.
Keywords: Period transformation, warmth treatment method, abrasion resistance, stainless steel 304, abrasion experiments.
