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 کاملFracture Mechanism of CoCrMo Porous Nano-composite Prepared by Powder Metallurgy Route
The main aim of this research was to find the mechanism for the failure of the CoCrMo porous nano-composite by characterizing microstructural changes and fractured surface after compression test. For this purpose, porous nano-composites were prepared with the addition of bioactive glass nano-powder to Co-base alloy with 22.5% porosity by the combination of space-holder and powder metallurgy tec...
متن کاملCharacterization of the microstructure, tensile and creep behavior of powder metallurgy processed and rolled Ti-6Al-4V-1B Alloy
This work investigated the microstructure and elevated-temperature (400-475C) tensile and tensile-creep deformation behavior of a powder metallurgy (PM) rolled Ti-6Al-4V-1B(wt.%) alloy. The PM rolled Ti-6Al-4V-1B alloy exhibited a duplex microstructure, and it did not exhibit a strong α-phase texture compared with the PM extruded Ti-6Al-4V-1B alloy. The PM rolled Ti6Al-4V-1B alloy exhibited gre...
متن کاملINFLUENCE OF GRAIN SIZE ON MICROSTRUCTURE AND POROSITY OF BIOCOMPTIBLE TI-35,5Nb-5,7Ta ALLOY PROCESSED VIA POWDER METALLURGY
Beta-titanium alloys containing only fully biocompatible elements are very perspective materials for production of bioimplants. They have good properties for use as biomaterials, including above mentioned biochemical compatibility, low elastic modulus (important for biomechanical compatibility), in comparisson with previously used alloys. Moreover they are suitable for forging. Perspective meth...
متن کاملProduction of silicon carbide Al 2124 alloy functionally graded materials by mechanical powder metallurgy technique
ub lis he d by M an ey P ub lis hi ng ( c) IO M C om m un ic at io ns L td A mechanical powder metallurgy process involving a vibration stage before cold and hot compaction has been developed to manufacture functionally graded materials (FGMs). The microstructure and mechanical properties of p 2124 FGMs produced by this process have been studied. It was found that the vibration stage modified t...
