The results show that 20CrMo steel after 880 Carbonitriding of low alloy steels Mechanical and This is of importance to the design of triple-phase steels containing an austenite that has optimum stability,to facilitate stress-induced transformation under dynamic loading.

Characterization of deformation instability in modified

This indicates 20CrMo steel is a positive strain rate sensitive material.This behavior can be explained in terms of rate of dislocation generation and accumulation [14].The stressstrain curve China Double Helical Gear of Gear Pump - China Big Gear China Double Helical Gear of Gear Pump,Find details about China Big Gear,Big Gear Shaft from Double Helical Gear of Gear Pump - LUOYANG EVON ENGINEERING CO.,LTD.China Short Pitch Precision Roller Chains and Bush Chains China Short Pitch Precision Roller Chains and Bush Chains 28A Series Plate Wheel,Find details about China Roller Chain,Sprocket from Short Pitch Precision Roller Chains and Bush Chains 28A Series Plate Wheel

Helical Gear ReducersHot deformation behavior of Mg-8Li-3Al-2Zn-0.2Zr alloy

Apr 01,2019·The hot deformation behavior of as-homogenized Mg-8Li-3Al-2Zn-0.2Zr alloy was investigated by compression test at 473623 K/0.0011 s 1.The relationship of flow stress,temperature,strain rate,and strain is represented by the Zener-Hollomon parameter including Arrhenius term,and the average activation energy of deformation is calculated as 107.55 kJmol 1.Physically based constitutive analysis and microstructural Oct 05,2016·The hot compression tests of AA7050 aluminum alloy were conducted under conditions of 603693 K and 0.00110 s 1,and the related microstructures were observed.Physically based constitutive analysis was conducted to describe the flow behaviors,which can relate the microstructural evolution with flow behaviors for high stacking fault energy (SFE) and/or precipitation-strengthened

Research on Sol-Gel Transition Process of Gelatin

As a kind of functional material,gelatin gel is widely used in controlled drug release,biological tissue engineering,photographic and food industries.Plenty of studies on the gelatin gel have been carried out by researchers,which include gelation mechanisms,gelation kinetics,analysis on the crosslinked structure and macroscopic performance during the gelation process.Science China Technological Sciences Journal Impact IF About.Science China Technological Sciences,an academic journal cosponsored by the Chinese Academy of Sciences and the National Natural Science Foundation of China,and published by Science China Press,is committed to publishing high-quality,original results in both basic and applied research.Science China Technological Sciences is published in both print and electronic forms.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next
