Composites of clay minerals mixed with sodium silicate as new inorganic flame retardants for wood have been investigated.
Iron impurity in aluminum alloys forms coarse needle-shaped intermetallic compounds during solidification and hampers the recycling process. To control morphology of material microstructure, an experiment was carried out where ultrasonic vibration applied to melt solidification. Aluminum-Silicon-Iron containing 4 mass% iron were melted solidified. The primary crystals that formed from melts identified as Al3Fe, α-AlSiFe (Al7.4SiFe2) β-AlSiFe (Al9Si2Fe2). refinement these thought occur with...
Previous research has shown that Fe–Mn–Cr–Ni–Si alloys offer excellent low-cycle fatigue resistance via reversible bidirectional transformation between face-centered cubic (FCC) γ-austenite and hexagonal closed-packed (HCP) ε-martensite. The alloy shows superior life is used for seismic damping applications, but there have been concerns over their to highly corrosive environments. In this study, Fe–15Mn–aCr–bNi–4Si were prepared with different Cr Ni concentrations evaluate the effects on...
Fe-15Mn-10Cr-8Ni-4Si is a newly developed alloy for seismic damper applications. The low- and high-cycle fatigue (LCF HCF) properties of this was investigated in study. LCF resistance found to be superior that other materials. inelastic component established the main contributor life Fe-15Mn-10Cr-8Ni-4Si, including at relatively low strain levels. This demonstrated gradual mild cyclic hardening behavior wide range strains. In terms HCF property, limit 262.5 MPa, which 96% 0.2% proof stress...
Considerable R&D efforts in last decade have identified several promising lead-free tin alloys for the replacement of lead-containing solders microelectronic applications. However, it is difficult or uneconomical to produce high-quality solder balls industrially by means conventional atomization methods. To acceptable efficiently and industrially, a novel powder-making process change active voice. Hybrid Atomization that combines free fall gas centrifugal effectively, was invented developed...
Reverse transformation behavior and the microstructures of ε-martensite induced by two different methods cooling deformation in Fe-28Mn-6Si-5Cr shape memory alloy was investigated. In situ heating X-ray diffraction (up to 673 K) applied cooled deformed specimens observe reverse behavior. The were analyzed electron backscattering diffraction. From patterns, start temperature (As) found be lower than that specimen, while finish (Af) higher specimen. back-scattering (EBSD) analysis revealed a...
Control of noise and vibration remains to be solved for the lowering environmental load in all industrial fields. It is necessary take account problem when designing machines or structures. Therefore development damping materials suitable structural parts that are easy process recycle, urgently required. Mn-Cu alloys show most satisfactory mechanical properties capacity among developed alloys. The M2052 alloy, which has a nominal composition Mn-20Cu-5Ni-2Fe (at%), shows both high strength....
The feasibility of intelligent utilization iron-aluminum scraps is explored in this work. Through adding aluminum which contained the to cast iron, changes wear resistance, heat resistance and damping property aluminum-alloyed irons were systematically investigated. Superior properties obviously manifested with certain contents. Iron-aluminum mixed are expected be utilized as a raw material for high quality irons.
An AZ91 alloy pretreated by ultrasonic vibration (UV) was subjected to extrusion refine the microstructure. The results indicated that UV pretreatment had a strong influence on microstructure evolution and mechanical properties of extruded alloy. With pretreatment, fine uniform with an average grain size 13.5 μm obtained, fraction fiber-like, partially-recrystallized, structure markedly reduced. In addition superior such as yield strength 256 MPa, ultimate tensile 320 MPa fracture elongation...
Influences of static strain on the damping capacity in Mn-based M2052 and Fe–6Al alloys were studied with forced flexural oscillation method by using a dynamic mechanical analyzer (DMA). The surface was applied 3-point bending specimens range 1.0×10−5–2.0×10−4. alloy showed continuous increase, but that decrease increasing below 1.0×10−4. variation fitted an exponential function, index turned out to be 0.25 −0.5 for alloys, respectively. Static strains vicinity 1.0×10−4 caused formation...
