Recently, the micro-scale abrasive wear test has gained large acceptance in universities and research centers, being widely used in studies on the abrasive wear of materials. Experiments were conducted using a pin-on-disk device to study the abrasive wear of Fe-Mn-Si-Cr-Ni shape memory stainless steel. It was used different chemical composition projects: Fe-10,3Mn-5,3Si-9,9Cr-4,9Ni ; Fe-13,7Mn-5,6Si-8,6Cr-5,1Ni e Fe-14,2Mn-5,3Si-8,8Cr-4,6Ni. Samples were submitted to different austenitizing temperatures (900oC, 950oC, 1,000oC and 1,050oC) to obtain different grain sizes. The specimens were water quenched until room temperature. The samples were analysed on optical microscopy and scanning electron microscopy before starting the test and after concluding the experiments. The abrasive wear behavior of each test condition is presented.
Summary: This work aims to study the abrasive wear of 3 different Fe-Mn-Si-Cr-Ni shape memory stainless steel using a pin-on-disk micro-abrasive wear tests. Samples were submitted to different austenitizing temperatures (from 900oC to 1,050oC) and water quenched until room temperature. The samples were analysed on optical microscopy and scanning electron microscopy before starting the test and after concluding the experiments. The abrasive wear behavior of each test condition was presented.
