Functionally graded (FG) aluminum foam containing A1050 pure and ADC12 alloy was fabricated. The FG has the potential for its location of deformation to be controlled. Moreover, a with plateau regions stresses corresponding those uniform foams obtained.
Effect of porosities on the fatigue properties high-pressure die cast aluminium alloy is addressed. Three-dimensional shape and location in specimen were inspected by X-ray CT to determine which pore affects crack. The tension-compression test was carried out inspection also conducted for all specimens before after test. By comparing with SEM observation fracture surface, we confirmed that crack initiation restricted shrinkage pores near inner large not source But found a cluster cavities...
Background/purpose Does the morphology of wrinkles alter gradually with aging or suddenly at a certain age? On basis theoretic wrinkle simulation ideal skin, we have suggested that changes from stratum corneum wrinkling to epidermis wrinkling; former induces shallow fine furrows, and latter deep prominent wrinkles. To examine existence drastic change in morphology, developed new measurement system for facial skin test. Methods The mechanical compression test was carried out 102 Japanese...
Aluminum foam was fabricated without the use of a blowing agent by friction stir processing route using ADC12 aluminum alloy die castings, which contain large number gas pores. In this study, foams with porosity 50–77% were successfully fabricated, and pore structures compression properties obtained investigated. The had smaller pores than commercially available foam. Moreover, size almost same regardless porosity. According to results tests, plateau stress energy absorption tend decrease...
Aluminum foam has received considerable attention in various fields and is expected to be used as an engineering material owing its high energy absorption properties light weight. To improve the mechanical of aluminum foam, combining it with dense tubes, such foam-filled was considered necessary. In this study, steel tube, which consisted ADC12 a thin-wall successfully fabricated by friction welding. It shown that diffusion bonding layer thickness approximately 10 μm formed, indicating...
It has been suggested that spiriferide morphologies have evolved to adapt a variety of environmental conditions. Through computational fluid dynamics approach, we examined how the original form was optimized for lotic condition, specifically addressing functionalization Devonian brachiopod Paraspirifer bownockeri generate passive feeding flows. The results using four models, each which differed in development shell depression, i.e. sulcus, showed deeper sulcus functions create strong spiral...
An aluminum foam sandwich was fabricated by FSP route. In this process, both the fabrication of a foamable precursor and metallurgical bonding between dense steel sheet can be simultaneously conducted. Although intermetallic compounds consisting Fe2Al5 FeAl3 were generated, tensile tests revealed that strength interface relatively high compared with porosity approximately 80%.
Al foam has been used in a wide range of applications owing to its light weight, high energy absorption and sound insulation. One the promising processes for fabricating involves use foamable precursor. In this study, ADC12 foams with porosities 67%-78% were fabricated from alloy die castings without using blowing agent by friction stir processing route. The pore structure tensile properties investigated compared those commercially available ALPORAS. From X-ray computed tomography (X-ray CT)...
Aluminum foam is usually used as the core of composite materials by combining it with dense materials, such in Al sandwich panels and Al-foam-filled tubes, owing to its low tensile bending strengths. In this study, all-Al foam-filled tubes consisting ADC12 Al-Si-Cu die-cast aluminum alloy a A1050 commercially pure tube metal bonding were fabricated friction welding. First, was found that precursor firmly bonded throughout inner wall without gap between No deformation or foaming observed...
As a new fabrication method of porous aluminum with the advantages high productivity and low manufacturing cost, authors proposed called "FSP route precursor method". FSP (friction stir processing) is solid-state process involving generation friction heat intense plastic flow simply by inserting rotating tool allowing it to traverse through alloy matrix. In this method, manufactured mixing blowing agent powder stabilization into matrix using stirring action FSP. Then, can be obtained foaming...
Porous Al was fabricated by combining a sintering dissolution process and friction powder compaction process. using Cu die exhibited superior mechanical properties to that an had fine pore structure, which is attributed the high load temperature during when die.
