MICROSTRUCTURE AND INCLUSION CHARACTERIZATION IN THE SIMULATED COARSE-GRAIN HEAT AFFECTED ZONE WITH LARGE HEAT INPUT OF A Ti-Zr-MICROALLOYED HSLA STEEL X.Chen1,Y.T.Chen1,Q.F.Ding1,J.Zeng1... heat affected zone (CGHAZ) of a Ti-Zr-treated high strength low alloy (HSLA) steel have been investigated. The microstructure of the simulated CGHAZ dominantly consisted of intragranular acicular......
Microstructure and mechanical performances of CGHAZ for oil tank steel during high heat input weldingGuo-Li Liang1,2,3,Shan-Wu Yang1,Hui-Bin Wu2,Xue-Li Liu21. Department of Material Physics... input welding and declined sharply with the heat input increasing, while the effects of heat input on impact toughness are very weak for the low titanium content steel, impact toughness of which......
of friction-stir-welded 6 xxx-series alloys with experimentally measured welding heat input. A calorimetrical method was utilized to experimentally measure the welding heat input in the friction stir welded of aluminum alloy 6063-T5. Good correlations between the input variables, i.e., welding parameters and physical properties of the materials, and the welding heat inputs obtained......
Influence of Heat Input on Martensite Formation and Impact Property of Ferritic-Austenitic Dissimilar Weld MetalsM. Mukherjee,T.K. PalWelding Technology Centre, Metallurgical and Material Engineering Department, Jadavpur University摘 要:The effect of heat input on martensite formation and impact properties of gas metal arc welded modified ferritic......
crystals. Moreover, the interface layer shape also depends on its position in the joint. Under the high heat input, dendritic or granular intermetallic compounds dispersively distribute in brazing seam... and corrosion resistance[4-5]. In laser brazing, the great temperature gradient is obtained due to the rapid heating and low heat input. And the short existing time of melting filler metal......
J. Cent. South Univ. (2018) 25: 1358-1366 DOI: https://doi.org/10.1007/s11771-018-3832-6 Effect of heat input on microstructure and mechanical properties of butt-welded dissimilar magnesium alloys... Abstract: The effects of heat input on the microstructures and mechanical properties of tungsten inert gas (TIG) butt-welded AZ31/MB3 dissimilar Mg alloys joint were investigated by microstructural......
