Subsurface damage of ceramic paticulate reinforced Al–Li alloy composite induced by scratching at an elevated temperature
نویسندگان
چکیده
The wear resistance mechanisms of a silicon carbide (SiC) paticulate reinforced Al–Li alloy composite at 250°C by a pyramidal indenter have been studied. It is found that the subsurface damages that control the wear resistance are: generation of dislocations and cracks in the SiC particles, interface debonding between matrix and reinforcements and plastic deformation of the matrix. © 1998 Elsevier Science S.A.

EFFECTS OF ELEVATED TEMPERATURE ON MECHANICAL BEHAVIOR OF AN ALUMINUM METAL MATRIX COMPOSITE
Effects of temperature on properties and behavior of a 20 vol % particulate SiC reinforced 6061 aluminum alloy and 6061 unreinforced Al alloy were investigated. Yield strength and elongation to failure were measured as a function of test temperatures up to 180^oC. In addition, the effects of holding time at 180^ oC on tensile properties and fracture mechanisms of the materials at this temperatu...
متن کاملThe Dry Sliding Wear Properties of Nano-Sized TiCp/Al-Cu Composites at Elevated Temperatures
Nano-sized ceramic particle reinforced aluminum composites exhibit excellent room-temperature mechanical properties. However, there is limited research on the dry sliding wear behavior of those composites at elevated temperatures, which should be one of the major concerns on elevated temperature applications. Here the Al-Cu composites reinforced with nano-sized TiCp were fabricated. The dry sli...

This paper presents positron lifetime studies of the subsurface region of AK12 aluminium alloy and Al2O3-particle-reinforced AK12 aluminium alloy composite after sliding against steel in the pin-on-disc machine. The defect depth profile detected in the AK12 alloy extended up to 300 μm but for the composite AK12 the range of this profile was significantly shortened to less than ∼ 90 μm. The posi...
