the dynamic behavior of three high manganese steels with very different stacking faultenergy (sfe) values (4-30 mj/m2) were studied using high strain rate torsional tests. the hotrolledmicrostructure of the steel with the lowest sfe of 4 mj/m2 consisted of a duplex mixture ofaustenite and ε-martensite, but those of the other two steels were fully austenitic. the deformedmicrostructures were stu...

High-manganese austenitic steel has been developed as a new cryogenic for application in liquified natural gas (LNG) storage and fuel tanks, with improved fracture toughness safety at temperatures. Generally, the decreases lower temperatures; therefore, requires high to prevent unstable fractures. This study conducted ductile tests 30-mm-thick high-manganese evaluated its applicability LNG tank...

advanced high strength steels (ahss) have recently attracted great attention because of their superior mechanical properties. a modern group of these steels, known as twinning induced plasticity (twip) steels, shows a unique combination of strength and ductility even at high rates of strain. in order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...

High manganese austenitic steel has attracted increasing attention for its application in liquefied natural gas storage tank materials due to excellent ductility and low cost. This paper presents an overview of the research progress high recent years. As a structural material used at temperature environment, should not only have certain strength, but also good toughness prevent brittle fracture...
