STRUCTURE AND PROPERTIES OF ULTRAHIGH-STRENGTH STEELS on *FREE* shipping on qualifying cturer: ASTM. almost completely prevent the introduction of hydrogen into the HAZ and which produce a Introduction to Today's Ultrahigh-strength Structural Steels. Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also . The ultrahigh-strength steels used in aerospace applications are primarily alloys developed 25 or more years ago, which would seem to illustrate the conservatism of alloy producers. However, the now widespread use of AF, which was developed in the mids, suggests that new alloys will be adopted for aerospace applications if their mechanical Cited by:
Ultrahigh-carbon steels (UHCSs) are low-alloyed plain carbon steels containing 1–% carbon. These steels have remarkable structural properties when processed to achieve fine ferrite grains with fine spheroidized carbides. They can be made superplastic at intermediate temperatures. Further, they can be made hard with compression toughness and strong with Cited by: The ideal structural steel combines high strength with high fracture toughness. This dissertation discusses the toughening mechanism of the Fe/Co/Ni/Cr/Mo/C steel, AerMet , which has the highest toughness/strength combination among all commercial ultrahigh strength steels. The possibility of improving the toughness of this steel was examined by considering Cited by: Introduction.
