Abstract
The effect of nickel silicide on the friction properties of Cu-based wet sintered friction materials was investigated. The microstructure and mechanical properties of nickel silicide added Cu-based wet sintered friction materials were examined. Nickel silicide was prepared by mechanically alloying Ni and Si powder. Three types of Cu-based wet sintered..... More

Abstract
Pores and cracks are known as the main defects in metal additive manufacturing (MAM), including directed energy deposition(DED). A gaseous fume is often produced by laser flash (instantaneous high temperature) during laser processing, which may cause various defects such as porosity, lack of fusion, inhomogeneity, low flowability and composition change,.....

Abstract
In this study, a glass fiber is fabricated using a continuous spinning process from alkali resistant (AR) glass with 4 wt% zirconia. In order to confirm the melting properties of the marble glass, the raw material is placed into a Pt crucible and melted at 1650 ℃ for 2 h,..... More

Abstract
Torsion tests were performed on AA6082 samples to investigate their flow softening behavior and to determine optimum process conditions. Based on the experimental data and dynamic materials model, high strain processing maps were established which demonstrate the constitutive relationships among temperature, strain rate, strain and stress. The flow curves exhibited..... More
