Accelerated Threshold Fatigue Crack Growth Effect – Powder Metallurgy Aluminum Alloy
Fatigue crack growth (FCG) research conducted in the near threshold regime has identified a room temperature creep crack growth damage mechanism for a fine grain powder metallurgy (PM) aluminum alloy (8009). At very low ∆K, an abrupt acceleration in room temperature FCG rate occurs at high stress ratio (R = Kmin/Kmax). The near threshold accelerated FCG rates are exacerbated by increased levels...
متن کاملEffects of Friction Stir Process Parameters on Microstructure and Mechanical properties of Aluminum Powder Metallurgy Parts
The effects of friction stir processing (FSP) on the microstructure and mechanical properties of aluminum powder metallurgy (PM) parts was investigated. PM parts were then subjected to FSP at advancing speeds (v) of 40-200 mm/min and tool rotational speeds (ω) of 800-1600 rpm. Microhardness (HV) and tensile tests at room temperature were used to evaluate the mechanical properties of the frictio...
متن کاملFatigue Crack Growth in a Particulate TiB2-Reinforced Powder Metallurgy Iron-Based Composite
Fatigue crack growth behavior has been examined in a particulate titanium diboride (TiB2)–reinforced iron-based composite that had been produced via a mechanical alloying process. Comparison with equivalent unreinforced material indicated that fatigue crack growth resistance in the composite was superior to monolithic matrix material in the near-threshold regime. The composite exhibited relativ...
متن کاملAN INVESTIGATION ON ABRASIVE WEAR BEHAVIOUR OF Fe-C-Mo-FeCr COMPOSITE PRODUCED BY POWDER METALLURGY
In this study, the effect of chromium carbide (Cr7C3) on abrasive wear behavior of Fe-C-Mo-FeCr composite was investigated. Composite, which was produced by a powder metallurgy route was containing 3 wt.% Mo, 1.5 wt. % C and 4,8,12 wt. % FeCr with the different particle sizes. In the experiments, wear resistance of samples were determined using different loads by a pin on disc wear tester. Micr...
متن کاملProduction and microstructural investigation of Al-nano TiB2 composite produced by powder metallurgy technique
Automotive and aerospace industries are required to light materials which have high properties. This causes to reduce production cost and fuel consumption. One of these advanced materials that have been attracted at these decades is particulate metal matrix nanocomposites. These materials have a combination of ductile matrix alloy properties and ceramic reinforcement nanoparticles. Powder metal...
