| Abstract: | Corresponding microstructure is simulated at different peak temperature by means of welding thermal simulated technics.Through analysis of metalloscope,fracture morphology and impact toughness test of the sample,the effect of thermal cycle peak temperature on heat affected zone microstructure and properties of low alloy high strength tensile steel is investigated.Meanwhile the inner fine structure in martensite and bainite is observed by TEM.The microstructure comparison between shielded metal arc welding fusion zone and simulated zone is carried out. |
