dc.description.abstract | Quasicrystals have been used in various applications to improve wear resistance as well as friction. It is known that quasicrystal (i-phase) content and microstructure in alloys have a decisive effect on the mechanical properties and tribological performance. In this research, four (beta + i)-dual-phased quasicrystal alloys with different i-phase content and grain size were developed to alleviate the brittleness of the i-phase with the help of the soft beta-phase. The influences of the i-phase content and grain size were investigated through impact test, wear test, and analysis. Through the annealing process, the amount of the i-phase was increased by about 38% (59.24% -> 81.75%), and, besides, the grain size of the i-phase was simultaneously increased from 3.47 mu m up to 9.98 mu m. As the amount of i-phase increased, it was possible to increase the hardness from 712 HV to 763 HV. Meanwhile, the increased grain size (i-phase) reduced the contact stress of the grain during wear testing: thus, the specific wear rate could be decreased from 2.21 x 10(-4) mm(3)/Nm to 0.5 x 10(-4) mm(3)/Nm. Not only that, but an experimental wear equation was obtained using empirical data to predict the wear behavior of the dual-phased alloys. (C) 2020 Published by Elsevier Ltd. | - |
