Feb 24, 2015 · This study reports a detailed investigation of the microstructure and mechanical properties (wear resistance and tensile strength) of hardened and tempered AISI H13 tool steel substrate following laser cladding with AISI H13 tool steel powder in as-clad and after post-cladding conventional bulk isothermal tempering [at 823 K (550 °C) for 2 hours] heat treatment. Laser cladding Microstructures and mechanical properties of hot indirect Apr 15, 2021 · Phase identification was performed by a D/Max 2500 X-ray diffractometer (XRD, Cu target). The microstructures were examined by ZEISS Axio Imager A1m optical microscope (OM), JEOL JEM-2100 transmission electron microscope (TEM) and FEI Quanta FEG 250 scanning electron microscope (SEM) equipped with EDAX/TSL OIMTM system. Nomex Insulation Paper(Nhn) by Henan Yaan Electrical 5. Form:roll, sheet, strip Nomex insulation paper has good mechanical properties, such as tensile strength and edge tear resistance, as well as good electrical strength. NMN Flexible Laminates has the excellent high temperature resistance of NOMEX. It is mainly used for slot, slot cover and phase insulation in low-voltage motors.
Jul 30, 2019 · The measured dynamic mechanical properties for SMA strip were Storage Modulus, Loss Modulus, tan, and Stiffness, both at heating and cooling. Thus, the characteristic temperatures of the phase transitions (As, Af, Ms, Mf), of SMA strip were identified. Pressure Analysis of Dynamic Injection Molding and mechanical evolution history is changed due to this external vibration. Many studies have introduced the research work of the DIMT effect on the mechanical or electronic properties of plastics from the experimental perspective. For instance, Kikuchi et al.  improved Refinement of second-phase particles and grain structures The evolution of Al2Cu second phase particles and the mechanical properties of the produced workpieces were investigated. Post-peak flow softening is attributed to dynamic recrystallization
Abstract Metal additive manufacturing of dental prostheses consisting of cobaltchromiumtungsten (CoCrW) alloys poses an alternative to investment casting. However, metal additive manufacturing Study on Hydration and Mechanical Property of Portland
- AbstractIntroductionExperimental DetailsResults and DiscussionConclusionsData AvailabilityAcknowledgmentsIn this work, Portland cement- (OPC-) blended recycled plaster materials (R-CP) were prepared to find out their hydration and mechanical properties. It was found that the hydration of R-CP was accelerated by the rapid rehydrated ettringite (AFt), and the strength of R-CP was decreased by the reduced hemihydrate content and low strength of rehydrated AFt and CaCO3. On the contrary, consistent with the previous studies, the strength of OPC-blended plaster of Paris materials (POCP) was improveMicrostructural Characterization and Mechanical Properties Feb 19, 2015 · Mechanical Properties. The low-temperature impact toughness and hardness of the specimens subjected to the post-weld heat treatment were measured. Charpy impact tests were performed at 233 K (40 °C) using the Charpy V-notch (CVN) specimens in accordance with the standard of ASTM E23-02.
Study on Mechanical Properties and Energy Dissipation of Nov 02, 2020 · In order to understand the mechanical properties and energy dissipation law of frozen sandstone under impact loading, the cretaceous water-rich red sandstone was selected as the research object to conduct impact tests at different freezing temperatures (0°C, 10°C, 20°C, and 30°C). The test results suggested the following:(1) the peak stress and peak strain of frozen sandstone are
May 01, 2014 · Precipitates characteristics by TEM and XRD demonstrate that the microstructures of pre-ECAP, during-ECAP (dynamic), and post-ECAP aged specimens at 393 K mainly consist of phase, while remarkable amount of large particles is present in the microstructure of dynamic aged specimen at 423 K. Based on the results obtained, it can be deduced that maximum mechanical properties could be achieved when the microstructure mainly consisted of fine dispersion of phase.
