| Summary: | The hardness and compression stress of AISI 1020 steel surface improved by
various heat treatments such as carburizing and tempering were tested. Samples
prepared from the test materials were treated at gases carburizing medium and then
tempered. The hardness and compression distribution were measured. According to
ASTM E9-89a standard, the specimen was fabricated with length to diameter ratio of
2.0 and the surface must be flattening to proceed the compression test. The hardness
and compression strength of AISI 1020 were determined and compared with other
treated steel samples. Rockwell hardness testing machine was used to obtain the
hardness value based on ASTM E18-03 standard and compression testing was
conducted using Universal Testing Machine (UTM) to measure the compression
strength based on ASTM E9-89a standard. The hardness of carburized steel was not
as expected. Compression strength results are increased after the treatment with very
minimal values. |
