Aug 11, 2018 · In order to fill the existing gap, A357.0 (also known as A357 or A13570) powders are here processed by L-PBF and, for the first time, the fatigue behavior is investigated in the as-built state to (PDF) Fatigue property of ultra-long life of high strength PDF The ultra-long fatigue properties of four high strength 42CrMo steels, two of commercial and two of zero-inclusion, produced by different heat Find, read and cite all the research you

A simulation on microstructure sensitivity to very-high

fatigue strength of the steel in water was remarkably degrad ed compared with that in ai r and the fatigue strength in 3.5% NaCl solution was even lower than that in water. Therefore, it is necessary to further understand the fatigue behavior of very high streng th steels, which may be used in the SFT supporting system. * Corresponding author. Deformation and fatigue behaviors of case-hardened steels Aug 01, 2009 · This study investigates cyclic deformation and fatigue behavior of case-hardened solid specimens made of 1050 steel in torsion. Specimens were case-hardened to a case depth to diameter ratio of 0.2, which is typical of many applications. von Mises criterion was found to provide good predictions of the shear cyclic deformation based on the uniaxial behaviors of the core and the case Experimental Investigation of the Fatigue Behavior of

  • AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionsConflicts of InterestAcknowledgmentsFatigue behavior is an important factor for mechanical analysis of concrete members reinforced by basalt fiber reinforced polymer (BFRP) grid and polymer cement mortar (PCM) and plays a critical role in ensuring the safety of reinforced concrete bridges and other structures. In this study, on the basis of the static loading test results of concrete specimens reinforced by BFRP grid and PCM, a series of fatigue tests with different loading levels were conducted on interfaces between BFRP grid and concrete to invFatigue deformation of TiAl base alloys SpringerLinkThe fatigue behavior of Ti-36.3 wt pct Al and Ti-36.2 wt pct Al-4.65 wt pct Nb alloys was studied in the temperature range room temperature to 900°C. The microstructures of the alloys tested consisted predominantly of phase (TiAl) with a small volume fraction of phase (Ti3Al) distributed in lamellar form. The alloys were tested to failure in alternate tension-compression fatigue at

    Fatigue behavior of Nextel 312/Blackglas ceramic matrix

    Apr 02, 2012 · This study characterized a woven fabric reinforced ceramic matrix composite, Nextel 312/Blackglas, under monotonic and fatigue loading conditions at room and elevated (760°C) temperatures in order:(1) to investigate monotonic tensile and compressive loading behavior at room and elevated temperatures, (2) to establish the fatigue life diagrams (S - N curves) with tensile and zero Fatigue behavior of an austenitic steel of 300-series Jan 28, 2012 · Strain-controlled fatigue data of an austenitic stainless steel subjected to uniaxial state at different strain ratios with tensile and compressive mean strain are experimentally investigated to understand the fatigue phenomena when non-zero mean straining is involved. The fatigue test result indicates that mean stresses relax to very low level and the material experiences elastic-plastic Stress-life fatigue behaviour of aluminum alloy foams Mar 01, 2000 · All specimens fatigue tested in this study exhibited 3 stage fatigue failure behaviour, regardless of laser parameter, scan strategy or material used during the manufacturing process (Fig. 4).

    The Effects of Carburization on the Fatigue Crack Growth

    Jun 03, 2019 · Fatigue growth behavior analyses on three-dimensional local surface cracks are very important and complex under cyclic tensile, torsional, or multiaxial loading, and the behaviors are dependent on several factors, such as the material properties, surface conditions, load The fatigue damage behavior of a single crystal superalloy The uniaxial fatigue behavior of a single crystal superalloy, PWA 1480, is described. Both monotonic tensile and constant amplitude fatigue tests were conducted at room temperature, in an effort to assess the applicability of polycrystalline-based fatigue life prediction methods to a single crystal superalloy. The observed constant amplitude behavior correlated best using a stress-based life Uniaxial ratcheting and low-cycle fatigue failure Jun 16, 2011 · Uniaxial ratcheting and low-cycle fatigue failure behaviors of hot-rolled AZ91D magnesium alloy were studied by uniaxial cyclic stress-controlling tension deformation experiments. The effects of stress amplitude, mean stress and stress rate on the uniaxial ratcheting response and fatigue life of the hot-rolled AZ91D magnesium alloy were analyzed.

    High Temperature Tensile Properties and Fatigue Behavior

    High temperature fatigue behavior of a woven, SiC/SiC ceramic matrix composite (CMC) was investigated in air at two temperatures. The reinforcement for the CMC consisted of 5HS Sylramic(Trademark) fabric with a [0deg/90deg]4s lay-up. The SiC matrix material was infiltrated into the fiber-preform with a slurry-cast, melt-infiltration process.
