บทคัดย่อ: Main objective of the study was to investigate the prior austenite grain size distribution on microstructures and mechanical properties of welded micro-alloyed ABS EH36 steel. Shielded metal arc welding (SMAW) is processed using AWS A5.1 E7016, Dia. 2.6 mm welding electrode to prepare the weldments. A relationship between diameter and number of austenite and ferrite grains is analyzed to evaluate the mean austenite and ferrite grain size of the steel using Spektor’s model. The large grain size dominates the nucleation of ferrite, where the kinetics information should be related to the large grain and will contribute to meet the increasing low temperature toughness requirement of weld metals for the shipbuilding industry. Effectiveness yield stresses are controlled by applying different mean ferrite grain size according to Hall-Petch model. It is found that all grain size distribution and yield stresses of the three welded zones steel are in good correlation. © 2020, Prince of Songkla University. All rights reserved.
