On this examine, metal abrasion experiments ended up done on an computerized grinding device for stainless steel 304. Experiments had been carried out at diverse grinding moments for scenarios of warmth-dealt with samples and samples of their offer condition. The martensite period transformation all through grinding was examined as a result of microstructure observation success and area hardness, microhardness measurements. The investigate success clearly show which the abrasion resistance of SUS304 steel improves considerably when the sample is quenched in h2o Regardless that the floor hardness isn't going to enhance. This phenomenon could 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 soon after grinding, a substantial amount of martensite period appears on the floor of heat-addressed samples. The macro floor hardness from the metal will not increase, but microhardness in several places reveals a clear difference, particularly in regions with significant concentrations of martensite.
Keywords and phrases: Section transformation, heat procedure, abrasion resistance, stainless steel 304, abrasion experiments.
