SM490A 강의 저온에서의 인장, 충격 및 피로 특성

초록

In this study, tensile, impact and fatigue behaviour of SM490A at low temperatures was studied. Rectangular plate-type specimens according to ASTM Standards were used for tensile and fatigue tests. For impact tests, Charpy V-notch specimens were used. Tests were carried out at 20, -10 and -40 . As temperatures increase, tensile and fatigue strengths increase too, but impact absorption energy decreases.
